Spring 2.0 has marked a major advance in the Spring Framework. While still maintaining backwards compatibility, this release adds quite a few new features. What are those features and how do they add value? Come by and see.

In this session we'll provide a practical tour of what's new in Spring 2.0. Spring 1.x users who are looking to upgrade to Spring 2.0 will love this session. If you're not using Spring already, this talk will give a great overview of the things you're missing out by not using Spring 2.0.

The talk will highlight new configuration strategies, Spring AOP, bean scoping, JPA support, JMS improvements, new Spring MVC features, VM languages, and much more.

To today's JEE developer, there are two indispensable tools for creating applications; Spring and Hibernate. Together these two frameworks comprise one of the most powerful and often used stacks in the industry. While it is possible to do amazing things it's not always obvious how best to use them to maximize value. This session aims to correct that.

In this session, we'll start by addressing the basic design of an application using Spring and Hibernate. Once we've established some baseline best practices, we'll focus on how to best use Hibernate (both 2 and 3) in the persistence tier. We'll take a look at the use of Spring's HibernateTemplate and some new strategies in Spring 2.0. To finish with a look to the future, we'll explore use of JPA (Hibernate implementation) with Spring 2.0.

Security is one of the major requirements in modern day enterprise applications and yet it is also one of the weakest parts of most developers toolboxes. The problem is of course that security is HARD! It turns out that rather than reinventing the wheel for each application, developers can turn to a great security framework out there already; Acegi.

In this session we'll discuss a little known but widely used Spring sub-project called Acegi Security. Acegi is a great tool for implementing security at the URL, method, and domain object layers and can greatly simplify security requirement fulfillment for enterprise applications. The first part of the session will focus primarily on some basic security concepts and where Acegi fits into the equation. The second part of the session will focus on basic design and usage principals of Acegi. The final segment will be a live coding example where we actually take an application and add all three levels of Acegi security to it. As a bonus, I'll even tell you the story of how the Acegi name came about :)

You're winding down a project and you get that dreaded email from your project manager, "How hard would it be to add some performance monitoring to the system?" Well, after this session, you'll be able to respond, "No problem at all!" It turns out that with a pinch of AOP and a dash of JMX, you can introduce amazing management and monitoring capabilities without changing your mainline code one bit.

In this session, we explore the technologies of AOP and JMX and how they can be used together to transparently add management and monitoring in a completely non-invasive way. We'll explore some of the various AOP packages including Spring AOP and AspectJ and how they can be used to apply management and monitoring inline to an application. Once we've added this functionality we'll how to expose it using JMX using Spring's JMX support and consume it using JConsole or Spring.

If you're tentative about introducing AOP or JMX into your application, come take a look at some of the cool things you can do with them and how easy it can be.

This talk avoids SOA hype and gets to the meat of the matter: how do you implement a Service-Oriented Architecture, what are the technological pitfalls, how do you test it, and what traps should you avoid. No marketecture: just implementation details.

No subject has been subject to more recent hype than Service-Oriented Architecture (I think it was because of a really good article in an in-flight magazine). For whatever the reason, the CxO has decided that we need one. It's up to you to implement it. This session is all about the technical considerations required to implement a service oriented architecture. It discusses technology choices, what is in (and out) of SOA's scope, how to implement transformations, routing, and other key services, how to version endpoints, and finally testing and debugging SOA. This session is marketecture free: it covers the details you need to implement this style of architecture.

Session Topics:

• What SOA means to those who must implement it
• Technology choices
• Routing
• The WS deathstar
• MOM
• Implementing transformations
• Versioning services
• Testing SOA
• Debugging SOA implementations

No one writes perfect code: even the best developers fall into bad habits and traps. These topics from The Productive Programmer illustrate blind spots and helps you write better code.

It is too easy to get into a coding slump and not realize it. This talk revitalizes your relationship to code, forcing you to rethink some of the thing that you take for granted and showing new approaches to solving hard problems. It covers topics that range from improve the overall structure of your code to the way you write JavaBeans, with lots of examples. Everything in this talk may not be new to you, but I guarantee that you'll see some things that will make you reevaluate the way you think about your code.

This session discusses building Domain Specific Languages and DSL-style code in Java, Groovy, and Ruby. It discusses the different types of DSLs, details on how to implement them in Java, Groovy, and Ruby, and example problem domains where DSLs make sense.

You've heard all the hype for the past couple of years: Domain Specific Languages (DSLs) are going to take over the world. This session demystifies this topic in 2 ways: by providing concrete definitions for styles and applicability of DSLs and showing how to implement these different styles. I build up definitions for the different types of DSLs in static (Java) and dynamic (Groovy and Ruby) languages. Then, I discuss building DSLs as internal (i.e., built on top of an underlying language) and external (built using a preprocessor or grammar), with examples of each. Throughout this session, I discuss the applicability of this style of development and show targeted examples. I discuss fluent interfaces and techniques for building them, including problems. Incidentally, I show some cool language features of both Groovy and Ruby that make building DSLs easier in those languages.

Session Topics:

• Why DSLs
• Abstraction
• Internal vs. External DSLs
• Fluent Interfaces
• Building Blocks
• Internal DSLs
• In Java
• In Groovy
• In Ruby
• The Stopping Problem
• Best Practices and Applications

As out applications have spilled from the server across the wire to the web tier, we increasingly must debug and test in the browser. This session covers debugging and testing tools for clients, JavaScript, and Ajax.

As the browser has become important again, our applications have spilled out of the server side to the web tier, and now we have to debug and test there. This session is all about debugging and testing the web tier. I discuss the tools Firebug, Venkman, the Developer's toolbar, and bookmarklets for debugging JavaScript, Ajax, and general browser behavior. Then, I discuss testing the web tier, first with unit testing via JsUnit, the user acceptance testing with Selenium and Sahi. This session is packed with examples and demonstrations, including real-world scenarios and pitfalls.

Session Topics:

• Debugging
• Firebug
• Venkman
• Developer's Toolbar

This session discusses advanced Selenium techniques for testing web applications. It discusses techniques for both TestRunner and Remote Control Selenium, including data driven tests, creating branch points, testing Ajax applications, creating flexible tests, integration with continuous integration, and tons more.

By now, just about everyone has heard of Selenium, the revolutionary open source testing tool for web applications. This session takes Selenium to the next level, showing how to handle complex, real world scenarios in Selenium. It discusses Selenium setup for both TestRunner and Remote Control. Mostly, though, this session delves into specific techniques for testing real world kinds of behaviors in web applications. I discuss data driven tests, generated tests, decision points in tests, interactive Remote Control, integration with continuous integration, testing Ajax applications (including applications that only Selenium can test), and future directions. This session will turn up the volume on your testing to "11".

Session Topics:

• Generating random values
• Data-driven tests
• Remote control Selenium
• Setup
• Interactive mode
• Writing and running tests
• Decisions, decisions

This session discusses how to use the Productive Programmer principles of acceleration, focus, and indirection to become a more productive programmer. This session describes these principles, but the primary focus of this session is demonstration of these principles with real-world examples.

In The Productive Programmer, David Bock and I identify 5 principles of productivity: this talk goes into great detail on 3 of those principles. The session defines the principles and describes their use, but the primary focus of this talk is on real-world examples of how you can use these principles to make yourself a more productive programmer. Acceleration covers keyboard shortcuts (including ways to make better use of them) in both IntelliJ and Eclipse. Focus describes how you can modify both the operating system and your code base to eliminate noise. Indirection shows how a simple concept can have profound effects, including how to share a common set of plugins across an entire Eclipse project. This talk includes tons of examples, all culled from real-world projects.

Session Topics:

• The Productive Programmer
• Acceleration defined
• Applying Acceleration
• Keyboard shortcuts
• Plug-ins
• Getting around in a hurry
• Launching stuff
• Focus defined
• Applying Focus
• Get out of the trees
• Searching several ways
• Code focus
• Avoiding the trash pile
• Indirection
• Applying Indirection
• links vs. shortcuts
• Sharing stuff
• Canonical plug-ins
• Environment isolation

The session defines the principles and describes their use, but the primary focus of this talk is on real-world examples of how you can use these principles to make yourself a more productive programmer. Canonicality (the DRY principle from The Pragmatic Programmer) discourages repeating artifacts in projects. This talk shows effective ways to avoid this repetition. For example, I show how to reuse documentation via a Subversion hook that posts comments to a Wiki with an RSS feed. Automation refers to making the computer do more work for you. This talk includes tons of examples, all culled from real-world projects.

If you've never used Reflection (java.lang.reflect), you don't know what you're missing. In this presentation, we'll take a code-first, soup-to-nuts look at the Java Reflection APIs, from how to examine the class metadata that Reflection provides, to using annotations to enhance that metadata with your own information, even through the use of Java Dynamic Proxies to create flexible object "interceptors" that can layer services in front of ordinary method calls with nothing more complicated and an interface and a factory.

For beginning to intermediate Java developers who've not used Reflection or Dynamic Proxies before.

By Ted Neward

If you've ever gotten a ClassCastException and just knew the runtime was wrong about it, or found yourself copying .jar files all over your production server just to get your code to run, then you probably find the Java ClassLoader mechanism to be deep, dark, mysterious, and incomprehensible. Take a deep breath, and relax--ClassLoaders aren't as bad as they seem at first, once you understand a few basic rules regarding their operation, and have a bit more tools in your belt to diagnose ClassLoader problems. And once you've got that, and hear about ClassLoaders' ability to run multiple versions of the same code at the same time, and to provide isolation barriers inside your application, or even compile code on the fly from source form, you might just find that you like ClassLoaders after all... maybe.

For a beginning to intermediate Java audience.

Permissions, policy, SecurityExceptions, oh my! The Java platform is a rich and powerful platform, complete with a rich and powerful security mechanism, but sometimes understanding it and how it works can be daunting and intimidating, and leave developers with the basic impression that it's mysterious and dark and incomprehensible. Nothing could be further from the truth, and in this presentation, we'll take a pragmatic, code-first look at the Java security platform, including Permissions, the SecurityManager and its successor, AccessController, the Policy class and policy file syntax, JAAS, and more.

For an intermediate-level audience.

Bugs? We all know your code has no bugs, but someday, you're going to find yourself tracking down a bug in somebody else's code, and that's when it's going to be helpful to have some basic ideas about bug-tracking in your toolbox. Learn to make use of the wealth of tools that the Java Standard Platform makes available to you--tools that your IDE may not know exist, tools that you can make use of even within a production environment.

Learn to use jdb, jconsole, jps, jstat, and other tools to identify and squash software defects that just won't reveal themselves during development. Then, just in case those tools aren't enough for you, we'll look at how to write your own, special-purpose tools using the same technology backplane.

By Ted Neward

If you've been keeping your ear to the ground, you may have heard some talk recently about "rules", "business rules" and "rules engines", but not necessarily any clear discussion on what they are, how to use or design them, or why they might be useful or important.

This presentation puts some concrete definition around what a "rule" is, how a "rule engine" like JESS (Java Expert System Shell) can enable your users to be more agile than they ever thought possible, where JSR-94 fits into both the J2EE and "lightweight" development environments, and how you can (finallY!) get out of the "infinite if-else game".

So you've convinced the boss that your new web application just has to have Ajax...but now what? With dozens of libraries making even the most blinkish of interactions trivial, how do you decided where to sprinkle the magic Ajax dust? This talk will give a plain old boring "web 1.0" an Ajax facelift with a focus on improving the user experience providing you with a game plan for introducing Ajax to your world.

Ajax might not be the most complex thing the average web developer has ever encountered but that doesn't mean building Ajax applications is without some quirks. While you can certainly use the raw technologies beneath Ajax or even roll your own framework, there are a number of well-designed open source libraries that you can take advantage of. After providing a quick survey of the field, this talk will feature live coding examples comparing and contrasting some of the more mature Ajax toolkits including Dojo, Prototype, script.aculo.us and YUI. We'll show you what these various libraries do and do not provide and give you some ideas about which ones make the most sense for your needs.

With all the attention being paid to Ruby and it's hip cousin Rails, many in the Java camp may be feeling like their party invitation is "lost in the mail". Fear not loyal Java lovers, the dynamic language meme is alive and well in your space! Between numerous JSRs and various languages, the JVM is becoming quite the dynamic disco. After an overview of what it means to be dynamic, this talk will look at JRuby, Groovy, and Rhino.

When starting a new project, most developers make sure that testing is a priority. However, only the lucky few live in the idyllic world of greenfield development; the vast majority of us must contend with code written when "test" was a four letter word and testing was the sole responsibility of that "other" organization. We'll examine some techniques for introducing testing - not just to your code but to the rest of your development organization.

Object-oriented scripting languages, or agile dynamic languages, as some like to call those, are gaining programmers' attention. Groovy bring this excitement to the Java platform with its ability to generate byte code. You can use Groovy instead of Java for some parts of your application. By learning it, you can switch between the languages where you consider fit.

In this session we will learn what Groovy is. We will take an example driven approach to look at interesting features. We will see how a piece of code you would write in Java can be written, elegantly, using Groovy. In addition to the current features, we will also discuss the state of the language and tools.

Domain Driven Design (DDD) is an approach that places emphasis on the domain model and carrying it into implementation. DDD is mostly repackaging of fundamental OO Design. It brings new emphasis to what we should be already doing, but often find it hard and confusing given the realities and complexities of our real world. In this presentation we will take a close look at what DDD is and how to use it for agile development. We will discuss several design options, and also look at some examples of good modeling and layering.

Domain Model Model and the implementation Domain objects and life cycle Developing with domain model Design strategies Refactoring

Rule based programming allows us to develop applications using declarative rules. These can simplify development in applications where such rules based knowledge is used for decision making.

In this presentation we will take a look at Drools and its evolution into JBoss Rules and how you can express rules including Groovy and other alternatives. We'll taken an example oriented approach to creating a sample application.

By Venkat Subramaniam

What do you get when you mix an agile, object-oriented, dynamic language with a lightweight, flexible, and extensible framework? You get a Groovier Spring. Spring allows you to develop using Groovy as much as Java. Groovy brings some neat concepts to the Java Platform that is hard to realize directly through the Java language. Using these capabilities can lead to elegant and easier Spring development.

In this presentation we will cover topics including: Strengths of Groovy Using Groovy in Spring Configuration Bean Development Deployment How it fits in

What benefit do new Java 6 features offer you. Are there issues with using these features. The objective of this presentation is not simply to introduce you to the features, but to the effective use of these as well.

We will take a close look at a number of features that you will be expected to know well when you program using Java 6.

By Venkat Subramaniam

Annotation is an interesting feature in Java. However, like any features, there are good uses and bad uses. When should you use Annotation? This presentation will answer that question for you.

In this presentation we will take a closer look at annotation. We will see how to write them, how to use them. Then we will take a look at examples of annotation in various Java applications/frameworks. We will discuss examples of good use and not so good use. We will then lay out some good practices to follow.

Unit testing tells you, the programmer, that your code (and the change) meets your expectations. How do you know if you are meeting your customers' expectations? Agile development is all about feedback and doing what's relevant to the customers, isn't it? Framework for Integration testing or Fit helps you to automate tests for customer expectations.

In this presentation we will learn how to write Fit tests and how to automate their execution. We will also use FitNesse.

Topics: Beyond Unit Testing Integration Testing Customer Expectations Writing Fit Tests Writing Fixtures Automating tests What is FitNesse Using FitNesse

By Venkat Subramaniam

Agile development is all about developing code and seeking feedback from your users to make sure you're developing what's relevant. When they suggest changes, those must be affordable and reliable. Grails, along with its facility to develop test driven, is a killer combination for rapidly developing web applications. In this ZePo (Zero PowerPoint) presentation, we will take a test driven approach to developing a small but fully functional web application in Grails. We will cover the fundamental features of Grails along with utilizing other capabilities like Ajax. At the end of this presentation, you not only be confident, but eager to roll your own web application using Grails.

In this session you will learn * How to create web application using Grails * Take a Test Driven Approach to developing the application * Understand Grails Conventions * Learn how to use the code generators and how to manually create domain models, controllers, and view * AJAX your application * Integrate with database

Internationalization and Localization in Java is easy, right? Everyone knows you just store your strings in some resource bundles, set the locale, wave your hands a little bit, and your application is good-to-go. Right? Maybe not... Java provides some great utilities to get started, but leaves you needing more when it comes to things like screen layout, cultural sensitivities, semantic differences in translation, use of color and iconography, and other issues.

This presenter spent 9 years developing applications for the U.S. State Department that have been deployed in dozens of countries and languages. While some aspects of internationalization and localization are trivial, there are plenty of issues that are not. If you have an application that you expect to localize into other locales, there will be information here that is invaluable to you. This talk is entertaining for the war-stories alone! No other no-fluff presentation will feature pictures of the presenter waiting in line behind a herd of sheep to cross a pontoon bridge into Bosnia.

By David Bock

For several years, I was a member of a team of people caught in the middle of a 200+ person software development company, with senior management wanting "buzzword compliant process improvement" such as CMMI, and engineers wanting more ?agile? solutions (and people on both sides confusing Agile with ad-hoc). We were responsible for sorting it all out. Reconciling this was a herculean effort, and can be a source of lessons learned for your own process improvement efforts. Are you trying to be more agile in your organization? Are you expecting it to be harder than it needs to be because of political and bureaucratic forces beyond your control? Do you have to "educate" your senior management to protect them from buzzwords? Come learn from my successes... and mistakes.

Introducing change into a large organization can be difficult, even when everyone is in agreement. By starting with 'the quick win' and fixing some real pain in your organization, you can begin to get people moving in the right direction. In this talk we will look at the kinds of quick process wins that are possible, and how to introduce new ideas into a large organization.

By David Bock

How many times have you started a new project only to find that several months into it, you have a big ball of code you have to plod through to try to get anything done? How many times have you been the ?new guy? on an established project where it seems like the code grew more like weeds and brambles than a well-tended garden? With a few good structural guidelines and several tools to help analyze the code, we can keep our project from turning into that big ball of mud, and we can salvage a project that is already headed down that path.

This talk will talk about everything from build processes, teamwork, and project structure through versioning, release plans, upgrde strategies, package dependencies, and more. Using real-world scenarios from two projects with 12-15 people working together over a 5-year time span, this presentation will offer advice based on multiple successful deliveries of real software.

Google quietly deprecated their SOAP search API at the end of 2006. While this doesn't mean that you should abandon SOAP, it does reflect a growing trend towards simpler dialects of web services. Google joins a number of popular websites (Yahoo, Flickr, YouTube, del.icio.us) that offer all of the benefits of web services without all of the complexity of SOAP.

REST isn't a specification or a framework -- it's a set of architectural principles. This means that you can begin using it immediately. No framework wars, no version mismatches. This talk demonstrates some of the more popular RESTful web services out there in the wild. It also shows you live examples of how to implement your own.

We'll look at the simplest form of REST -- GETful web services. We'll also look at more sophisticated RESTful interfaces that utilize all of the HTTP verbs (GET, POST, PUT, and DELETE) and MIME types. Finally, we'll look at Atom and the Atom Publishing Protocol -- the RESTful implementation that Google chose to replace its aging SOAP implementation.

By Scott Davis

I'm attracted to Groovy because of its spirit of inclusiveness. Because it extends my platform of choice, not replaces it -- include a single JAR in your classpath and you are Groovy-enabled. Because it offers full bidirectional integration with Java. Because it offers a nearly flat learning curve for experienced Java developers. Come see how you can use Groovy to augment your existing Java codebase.

We'll look at calling Groovy from Java. We'll look at calling Java from Groovy. We'll look at compiling Groovy code, JARring it up, and deploying it alongside Java.

Groovy offers the same level of integration with Ant. We'll look at Ant tasks that allow you to include Groovy in your build process. Or maybe you'd prefer to use the Groovy AntBuilder and completely manage your build in code. The choice is yours. The important thing is Groovy works along side your familiar toolkit instead of forcing you to replace it.

By Scott Davis

In this talk, we'll survey the web services exposed by leading websites (Google, Yahoo, Amazon, eBay) and discuss how they can be easily mocked up for testing purposes and to aid offline development. You'll see working examples of RESTful, SOAP, and JSON web services, as well as strategies for unit and functional testing your asynchronous, service-oriented architecture.

As more software engineers add unit testing to their everyday development regime, the concept of mock objects is becoming increasingly popular. Mock objects proxy more complicated objects, fulfilling their doppelganger's interface and behavior for testing purposes. Coding to interfaces instead of implementations is a best practice that applies equally well to POJOs and Web Services.

Web Services, too, are being added to our toolkit with increasing frequency. Building a true service-oriented architecture brings with it new challenges: how do you code against an external service? If that service is metered, how do you develop iteratively without using up your production budget in tests? These questions and more are answered in this talk.

Yahoo! is a company that eats its own dog food. They open sourced the Ajax code that drives many of their own websites, including their eponymous homepage, Yahoo! Mail, and Yahoo! News. Come see first hand how the various pieces of the library work together as a seamless whole.

We'll look at some of the everyday useful widgets like the onscreen JavaScript logger (which effectively brings Log4J-style logging to JavaScript) and the calendar components. We'll see how event handling is managed in a cross-brower fashion. We'll look at tabbed interfaces, multi-level menus, and panels and dialog boxes that end up making your website look more like a OS-level desktop than a traditional webpage.

The YUI library is included with the Grails web framework. It certainly works in all of the major frameworks as well, but the easy bootstrapping of Grails combined with the power of YUI library makes for the quickest way to get started with a minimum of hassle. No previous Groovy or Grails experience is required, so come to learn a little about all of these. Any experience JEE developer will feel right at home since Grails uses Spring and Hibernate under the covers.

By Scott Davis

Scott Davis is the Editor in Chief of aboutGroovy.com. The website, in addition to being, umm, about Groovy, is implemented in Grails. This talk shows you how to get started with Grails, but also talks about the experience of using it in a live, production web site.

Grails is a fully integrated, modern Java web development stack. In a single zip file, it includes a web server (Jetty), a database (HSQLDB), a build system (GANT, a Groovy/Ant hybrid), a logging framework (Log4J), and a unit testing framework (JUnit). It also includes mainstream libraries like Spring for dependency injection, Hibernate for Object/Relational mapping, Quartz for scheduling, and SiteMesh for page layout. For Ajax, Grails allows you to choose between three major included technology stacks: Prototype/script.aculo.us, the Yahoo UI library, and Dojo. Coupling the power of these mainstream libraries with the ease-of-use that Groovy offers, you have an unprecedented collection of technologies that will have you up and running in record time.

Grails maximizes the strengths of these familiar Java libraries while minimizing the XML jockeying it usually takes to get them all to play nicely with one another. It brings "Convention over Configuration" to Java. It uses Groovy as the language to glue the pieces together, which means that experienced JEE developers can learn Groovy in the context of libraries that they are already familiar with.

It is no exaggeration to say that you will have your first Grails application up and running in minutes. But Grails is more than about a quick start. In this talk, we'll look at ways to move beyond the default configurations. We'll deploy a Grails app to an external Tomcat instance instead of the included Jetty server. We'll move from the default HSQLDB database to MySQL. We'll include external JARs to bring new functionality to the mix.

In April 2005, annual growth rates for jobs in JavaServer Faces, Struts, and Ruby on Rails were all at about 0%. Today, Struts' growth rate still hovers around 0%, but JSF and Rails have taken off. At the end of 2007, both JSF and Rails were growing at a rate of between 400-500% annually (according to indeed.com).

JSF has passed the adoption tipping point, and is now the Java-based framework of choice, as is evidenced by its ecosystem. From vendors such as MyEclipse and RedHat to open source projects such as Seam, Facelets, and Ajax4JSF, JSF is where the action is.

Come see why JSF is so popular. In this code- and demo-intensive session, I'll show you the fundamentals of JSF.

This session is taught by a member of the JSF Expert Group for JSF 1.0 and 2.0., and co-author of the best-selling book on JSF: Core JavaServer Faces. David will take you through a whirlwind introduction to JSF including what JSF is, how it was developed, and how you can best take advantage of the technology. Here is a list of topics:

Components, managed beans, value expressions, and static navigation i18n, CSS, and actions The Faces Context and Faces messages The JSF Event Model Using JavaScript with JSF

This introduction to JSF also contains 5 live-code demos, where David will develop a simple, but robust application during the course of the session.

Prerequisite: Some knowledge of Java-based web applications, such as Struts, is a plus, but is not required. If you have a significant experience with JSF, you probably already know most of what's covered in this session.

An introduction to the popular Prototype JavaScript framework, and two frameworks built on top of Prototype: Scriptaculous and Rico.

Web2.0 is all about rich, interactive user interfaces (UIs), and these three frameworks provide the capabilities that you need to develop those UIs.

Prototype (prototype.conio.net) is a low-level JavaScript framework that adds significant features to JavaScript that make it easier for you to use the language and to incorporate Ajax calls in your applications.

Scriptaculous is a framework (script.aculo.us) built on top of Prototype that adds some pizazz to Prototype with features such as a wide array of special effects, animation, and drag and drop.

Rico is another framework (openrico.org) built on top of Prototype that, among other things, provides something known as behaviours, where you adorn plain-vanilla HTML with seemingly magical behaviours.

Come to this session and learn how to harness the power of these three frameworks.

JavaServer Faces is a perfect platform for implementing Web 2.0 interfaces with Ajax. This session explores how you can use these two potent technologies--JSF and Ajax--together to create applications that look and behave like desktop applications but run in the browser.

JavaServer Faces, with a mature component model and flexible lifecyle, is a perfect platform for implementing Web 2.0 user interfaces with Ajax. This session explores using JSF and Ajax to create applications that act like desktop applications but run in a browser.

We'll start with a quick look at implementing basic Ajax in a JSF application. Then, once your bloodthirst has been slaked, we'll dive deeper into Ajaxian Faces dynamics with a form completion demo that requires its implementor to understand two simple, but vital facts about JSF.

If you're savvy, you probably use client-side validation to augment your server side validation logic, which parenthetically, is no no-brainer in either of the leading web application frameworks, JSF or Rails. But anyway, client-side validation is old school. All the cool developers nowadays use Ajax to implement realtime validation, where you sneak a trip to the server as an unwary user types into your input fields. But to accomplish that, we'll have to dive even deeper into JSF, with concerns such as accessing view state and accounting for client-side state saving.

All of this Ajax development is great fun, but most of it is best relegated to components and frameworks, which are the topics that will wrap up our session. We'll see how to keep your JavaScript separate from your JSF components and how to pass JSP tag attributes all the way through to JavaScript. Finally, we'll take a look at Ajax4jsf, a JSF component library with a tag library that blends Ajax into JSF in a natural, intuitive way without having to write JavaScript.

As web developers, we've been handcuffed long enough by the shackles of Web 1.0 development. Come to this session and see the brave new world of Web 2.0 development with one of the hottest web application frameworks.

By David Geary

In this session, see how you can get Ruby On Rails-like productivity on the Java side of the house with this compelling combination of technologies.

JSF has been out for nearly three years now, and in many respects, the JSF specification has become a bit long in the tooth. Fortunately, the open source community has picked up the ball in a big way. In this 2-session presentation, we will explore three open source projects based on JSF--Seam, Facelets, and Ajax4jsf-- that will propel you into the stratosphere of productivity.

Seam is a framework from JBoss that combines the JSF and EJB3.0/Hibernate 3.0 frameworks into one component model. That means you only have to learn one framework to build compelling web applications.

This is the first of a two-part session, where we'll focus mostly on the Seam framework.

By David Geary

A continuation of a 2-session presentation on Seam, Facelets, and Ajax4jsf.

In the second part of this 2-session presentation, we'll turn our attention to Facelets and how you can use this compelling display technology with Seam.

We will also discuss Ajax4jsf and demonstrate how you can use that framework to create rich, interactive user interfaces for your JSF-based web applications.

By David Geary

Developing highly interactive web applications, for the most part requires knowledge of a wide array of technologies: HTML, CSS, JavaScript, XMLHttpRequest, JSP, JSF, etc.

With the Google Web Toolkit (GWT), Google turns that notion of development on its head. Instead, you implement Ajax applications by writing almost entirely in Java. You use an AWT-like API, which the Google compiler compiles to JavaScript that runs on the client.

In the early days of Java, application development with the AWT was relatively simple. You had to have a decent understanding of Java and AWT fundamentals, but once equipped with such knowledge, you could dive in and develop some impressive applications.

Ten years later, we have, in so many respects, gone significantly backwards. We've shoehorned technologies such as HTML into shoes for which they were never intended, and for our efforts, we have a mismatch of disparate technologies that one needs to knit together for a truly interactive web application.

This is the first session of a two-part presentation on the GWT, where I'll concentrate on GWT basics: implementing Ajax-enabled applications in Java, internationalization, testing, and remote procedure calls.

By David Geary

The second part of a 2-session presentation on the Google Web Toolkit.

In this session, we'll dive deeper into the GWT and explore some of it's more advanced aspects, such as implementing custom widgets, deploying your application in a servlet container, and implementing drag and drop.

By David Hussman

Have you heard about SCRUM or XP but never done it? If you want to give it a try, this session will allow you to participate in planning and executing several agile iterations. A working knowledge of either XP or SCRUM will be helpful but not mandatory.

After a brief introduction, we will assume roles, create a simple backlog, roadmap, and complete several iterations, finishing with a short retrospective.

By David Hussman

Successful project communities balance written requirements with a healthy amount of discussion. This is at the core of requirements that could be deemed "agile". Many agile projects choose to use user stories, but others may be using use cases or other forms of written requirements. This session is for anyone wanting to improve their requirements, including the creation of good requirement and the presentation styles that help people focus on creating great software products, and stop focusing on documents.

The session will focus on finding the people who are best suited to create and communicate agile requirements. We will examine how to ensure agility for user stories, use cases, and several other common forms of requirements. Without regard to the document type, we will show how to smoke out what needs to be captured in written form when, challenging the age old notion that more detail in requirements produces better software.

By David Hussman

Why is so much documentation worthless? Wouldn't is be nice if your documentation actually reflected what your system does? One way to do this is to create what is being called executable documentation or executable specifications. If you are struggling with ambiguous requirements, lack of contact with the business, or a chasm between development and testing, this session is for you.

What is executable documentation? Simply put, instead of adding more details to requirements, capture the desired system behavior in acceptance testing tools which are accessible to the entire project community. The session will focus on FIT, but it may include other tools for creating ED. History has shown me that ED - requirements that have two states (green and red) - helps project communities consistently create better software, faster!

By David Hussman

If your company is using agile or thinking about it, this session will show you how to plan and tracking an agile project. Examples projects will be discussed, including the glory and horrors. Various planning tools that help distributed teams will be presented as well as a collection of lo-fi tools which truly help find and address the issue that plagues so many projects: "when are we going to complete this project".

From using markers and post it notes to go faster tools, this session will examine ways to get agile going in various situations (e.g. small projects, large projects, or distributed projects). A variety of techniques and tools will be shown and discussed along with the pros and cons of each. Most importantly, you will come away with a variety of ways to start planning and tracking agile projects, so you can choose a path which fits best within your company.

By David Hussman

If you are thinking about, just starting, or in the midst of transitioning to agile, this session is overflowing with practices, tip, techniques, and experiences. Stop talking about whether or not you are doing agile and come learn how to setup and maintain agility that extends beyond a single project.

From your first agile steps to keeping the agile groove alive, this session will provide a guide for making agile work for you. Adopting agile without understanding (or showing) how it will help your project is a recipe for failure. From planning to tracking to coaching to coding, this session is filled with pragmatic experiences from a wide variety of projects and industries.

In today?s enterprise many individual applications are sewn together in a federated conglomeration to implement enterprise business processes; processes that are driven by the dynamic nature of sales, manufacturing, shipping, and human workflow intricacies. SOA & EDA are ideally suited to address these dynamic, large, and often times cross application and divisional problem domains.

This talk will explore the processes leading up to the creation of an EDA, the effort involved in designing an EDA in the SOA space, and real world examples illustrating implementation details. Specifically how an EDA is manifested with respect to its messaging infrastructure. We will explore the implementation of messaging patterns and see them in action as they help facilitate the dynamic nature of today?s businesses.

You've heard about unit testing but were daunted when it came time to put the pedal to the metal. That's because JUnit is just one tool and there's others you need to learn about, including the wonderful and wierd EasyMock and the easy and powerful TestNG.

Unit testing with JUnit only gets you so far; even when you've refactored your code and hidden all your implementations behinds interfaces you are still stuck with the problem of testing the individual pieces. If you've hit this point and despaired, know that there are tools to help ... including the wierd and wonderful EasyMock. We'll discuss unit testing in general, and how EasyMock is used to to generate mock objects, allowing you test each class in isolation. We'll also leave JUnit behind and investigate using TestNG, a modern and improved test framework. We'll then learn how to tame EasyMock's awkward API with some modest refactoring and naming conventions.

An introduction to the Apache Tapestry web application framework, which will explain the concepts and features of the framework with some simple applications. We'll discsuss Tapestry forms, request cycle, component object model. The use of several important components, including BeanForm and Table will be highlighted, along with meta-programming using the Trails framework.

Tapestry is a powerful open-source Java web application framework that stands apart from most other technologies used for creating web applications ? it is based on highly reusable components, which are assembled to form complete pages. This session will get you started with Tapestry, showing how to build a simple form-based application. Along the way, we'll see how Tapestry simplifies your job: We'll see how Tapestry HTML templates are easier to create and maintain than JavaServer pages (JSPs). We'll see how Tapestry's built in error reporting lets you find and correct errors with startling speed. We'll see how Tapestry takes over responsibility for building and interpreting application URLs, eliminating large amounts of boring, error-prone, manual coding. Most importantly, we'll see how Tapestry bridges from the stateless world of HTTP and servlets into a more natural, more productive world of actual object oriented engineering ? allowing you to build applications in terms of objects with methods and properties (a true revolution if you are used to traditional servlets).

We'll also take a peek into more advanced aspects of Tapestry, such as its input validation subsystem that provides server- and client-side validation, as well as more advanced Tapestry components such as Table (a powerful data grid), and the Trails meta-framework that creates complete applications without almost no coding. Once you've learned a little bit about Tapestry, you might find it hard to go back to your old approach!

Tapestry 5 is a complete rewrite of Tapestry from the ground up. It takes everything good about Tapestry and cranks the volume up to eleven, while removing the frustrating parts of using Tapestry. This session takes the wraps off this new and innovative technology, showing off important new features such as live class reloading (the ability to change your Java classes and continue using the application without interruption or redeployment), the simplified coding model, and the total lack of XML. This session is of interest to those already using Tapestry 4, and those new to Tapestry and ready to jump on the bandwagon.

Tapestry 5 really does take everything great about Tapestry and crank it up, all with the goal of making your job as a web developer easier. Being able to change your classes at will within a running application is just the tip of the iceberg; Tapestry 5 is designed to break down the barriers to developer productivity by simplifying every aspect of creating a web application.

Tapestry 4's base classes and abstract methods are all gone, replaced with pure POJOs and a handful of annotations. All the XML configuration of Tapestry has been removed as well. Tapestry 5 practices convention over configuration with a vengeance, introducing smart defaults and intelligent logic to let Tapestry do the right thing.

The explosion of popularity for dynamic languages on the JVM has changed the way we look at development. No longer is the Java platform tied to a single language, and no longer do you only have a single tool in your toolbox. Dynamic languages like Groovy, Python, Ruby, and others enable entirely new ways of solving our software problems. This session will explore one of those languages, Ruby, and show how it will make even complicated development tasks manageable and even fun.

JRuby is finally coming of age, presenting a viable new Ruby platform for both old and new Ruby developers. we'll first cover some basics about JRuby:

• History, including past design
• Current and future design plans
• Performance and compatibility metrics
• Where we go from here

JRuby also enables new ways of looking at programming on the Java platform. We'll look at some of the most popular:

• Calling Java APIs from Ruby code and implementing Java interfaces in Ruby
• Creating domain-specific languages to ease API use
• Metaprogramming in Ruby: fun and easy
• Interactive Java with the IRB console

By Charles Nutter

The Ruby programming language has exploded in popularity, spurred in part by the agility of the Rails web framework. Rails has in turn changed the way we look at web development. The two together are forcing developers to rethink how applications should be written. The world is changing. With JRuby you're now able to run Rails apps alongside your existing Java applications, calling the same services and leveraging the same infrastructure. All the scalability, reliability, and performance of Enterprise Java is now available to Rails developers.

JRuby aims to bring Ruby on Rails to Java developers and provide an alternative platform for Ruby developers. In this session we'll explain Ruby and show what makes it great, demonstrate how JRuby brings Ruby to Java and Java to Ruby, explore how JRuby on Rails brings agile web development to Java EE and Java EE's best features to Rails, and discuss the future of Ruby, Rails, and dynamic languages on the JVM.

We'll also talk about the status of JRuby on Rails, the current promise and perils of Rails on the JVM, and demonstrate bringing up a simple Rails app using JDBC for database access and calling into legacy services and APIs.

The Java NIO packages that were added in JDK 1.4 and these packages allow Java applications to perform true non-blocking IO operations. This presentation will cover the basics of the standard IO packages, which date back to the beginning of Java, and some of the shortcomings they have. This will be followed by coverage of the newer NIO packages and how they address these issues.

The NIO packages aren't simple to use and have a few dangerous pitfalls that many encounter when they first start using NIO. These pitfalls will be covered as well as solutions to each.

By Brian Pontarelli

This talk will cover many of the different types of SOA topologies from EJBs and WebServices all the way to message queues and tuple spaces. SOA has many different meanings but it never dictates a single implementation and this talk covers many of the most common implementations of a service oriented architecture.

During the course of this talk we'll cover EJBs, JMS and general message queues, Jini, JavaSpaces, WebServices and ESBs. We'll discuss the pros and cons of each topology and what makes each a better or worse solution for various problems. We'll also cover the fundamentals of network computing and why it is important to understand that SOA is distributed and the impact distribution has on the selection and implementation of the topology of an application.

Attendees should walk away with a more broad understanding of SOA and the numerous ways of implementing this architecture. They should also understand how to go about selecting the correct topology or mix of topologies to meet the needs of their applications.

By Brian Pontarelli

The ACEGI framework is a comprehensive security library built on top of the popular Spring Framework. This talk will cover the basics of using the ACEGI framework within a Java web application.

This talk will cover the details of getting started using ACEGI. We'll cover the ACEGI filter chain and how it works, login, logout, roles, authorization via access control lists, password encryption, and touch on annotation based security.

Attendees should walk away with the ability to start using ACEGI in their web applications and understand how all the ACEGI configuration work together to build custom security models.

By Brian Pontarelli

Writing APIs is fairly easy but writing an API that is usable and lives longer than a few days is hard. This talk discusses methodologies, tips and tricks for writing good APIs.

During the course of this talk we'll cover many of the common forms of APIs including base types, domains, services and toolkits and how to approach writing each type. We'll also cover the different between internal and external APIs and how to protect your code from your clients.

Attendees should take away a base set of tactics that assist in writing solid APIs.

By Brian Pontarelli

Learn how to create software builds that will stand the test of time and make the world a better place - okay perhaps just your development environment a better place. Builds are usually the tedious work that we all leave to the last minute or sometimes throw together as we build an application. But in most applications, builds contain complex logic and many dependencies, just as the application does. This presentation covers how to make a manageable and enjoyable build system using Apache Ant and a new Ant framework that is part of the JCatapult platform called JCatapult-Ant.

Most companies use the Apache Ant build system either for technical or political reasons. Many developers often wish they could use Maven 1 or 2 because of the plugin structure, dependency management and standardization it provides to applications. Ant sometimes gets a bad rap because it isn't the most simple tool to extend and build files often become large and unmanageable. Plus, Ant extensions are not simple to test and Ant lacks any concept of versioning. Even with all these problems, Ant can still be a great build environment and when used correctly can make creating builds a pleasure.

This presentation covers these topics:

• JCatapult's Ant framework
• Setting up a project
• Adding plugins
• Ant plugins - the what, how and why
• Plugin versioning
• Writing a new plugin
• Using Groovy inside plugins

If you are using Ant for your builds, but want a better solution that includes reusable plugins, dependency management and much more, this presentation will show you how to use JCatapult-Ant to accomplish just that. However, if you aren't able to use JCatapult-Ant, but still want to understand how to create better builds using Apache Ant, this presentation will show you the methodology behind JCatapult-Ant's plugins and allow you to create your own custom plugin system.

Attendees must have a good working knowledge of the Ant build system in order to understand the material in this talk. No other knowledge is required.

How do you keep a team scattered across time zones in sync?

It's difficult to keep a local team coordinated. When we add geographical distance to the equation, problems are immediately magnified. We'll talk about techniques that you can use to be sure everyone is sharing information and on the same page whether they're in the same office or in different time zones.

By Jared Richardson

Creating and maintaining a solid automated test suite is critical to an Agile strategy, but often we're just told to "Do it." In this talk we'll look at several pragmatic strategies for creating and building your suite.

We'll examine these strategies and then look at scenarios for using them next week. This presentation will get you started whether you're starting a new project or trying to clean up an existing one.

By Jared Richardson

Throughout our software careers we learn habits from our coworkers, from books we've read, and occasionally, from conferences we attend. Much of our competence comes from the tips and tricks we pick up as we go.

In this session, learn five of the techniques I've borrowed along the way. We'll discuss The List, code reviews, code change notifications, daily meetings, and tech leads. These techniques are often abused, but when used properly they can make a huge difference in how you develop software. Take this opportunity to add these practices to your toolkit.

By Jared Richardson

An overview of the Agile software approach from the book Ship It! A Practical Guide to Successful Software Projects.

This book provides a comprehensive look at the software life cycle and can be used to retool the way you, and your team, builds software. While we can't cover the entire book in nintey minutes, we can look how a holistic view of the software life cycle helps you improve your projects and makes your life easier.

Studies have suggested that somewhere between 30-70 percent of an application?s code and an equal percentage of a developer?s time is spent working with JDBC and SQL elements! It?s no wonder that software development teams looking to boost productivity are looking to persistence frameworks, but which one to choose? Options for a Java persistent framework include Hibernate, iBatis, Castor, JDO, the new Java Persistence API along with some proprietary frameworks. This presentation explains, demonstrates, and compares each of the viable options to one another. Attendees will learn how a graph of related Java objects can be persisted with each framework and they will gain an appreciation for the strengths and weaknesses of each approach. The talk will try to answer questions such as: how easy/difficult is it to setup each framework, which framework takes the most/least amount of time to learn, which framework works best on top of an existing database, which framework is the most flexible, and which framework provides the best performance with minimal tuning?

The talk will also compare the framework solutions to straight JDBC/SQL code to see how much real savings can be accomplished with a persistence framework. Using a medium sized example graph of objects that contains inheritance, various object-to-object associations and attributes of many different data types, attendees will be shown a demonstration of the setup, API and mapping facilities of each framework. Statistics on the footprint, performance and amount of code using each framework will be shared along with guidance on how the statistics might be affected in other graphs and application environments.

Attendees of this presentation should be familiar with Java, JDBC and relational database concepts.
