What does code + methodology have to do with one another? Everything! Agile projects focus on delivering working code, and tools exist to allow you to verify some quality metrics for your code. This session is a survey of tools and metrics that allow you to determine the quality of your code and strategies to "wire it" into your agile project.

Agile projects focus on delivering code. The responsibility for the quality of that code lies with developers. Yet most developers have a poor sense of how to gauge the quality of code, both during development and forensically. This talk lives on the boundary between what is important in agile projects and ways to verify code quality. It is both a survey of tools and metrics and strategies for proactively applying these techniques to ongoing projects. I talk about the Hawthorne effect, analysis tools (both byte and source code), useful metrics, tools for generating metrics, and how to analyze raw data into actionable tasks.

Session Topics:

• The Hawthorne Effect
• How Agility and Metrics Feed Each Other
• Analysis Tools
• FindBugs
• PMD/CPD
• Testing Metrics
• Cyclomatic Complexity
• Chidamber and Kemerer Object-oriented Metrics
• JDepend
• Code Change Risk Analyzer and Predictor for Java
• Panopticode
• Tools

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

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.

Session Outline:

1. TDD
2. Static Analysis
3. Good Citizenship
• getters and setters
• Constructors
• Static State
4. YAGNI
5. Occam and His Razor
6. Question Authority
• DSLs
• JavaBean Specification
7. SLAP
8. New Languages
9. Every Nuance
10. Anti-objects

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

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
• Bookmarklets

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
• Test Reusability

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

This session discusses how to use the Productive Programmer principles of automation and canonicality 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 2 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. 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.

Session Topics:

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.

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.

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.

Grails brings the powerful "coding by convention" paradigm to Groovy and Java. Grails is not just another flavor in the pool of web development frameworks for Java. Grails leverages the powerful dynamic features of Groovy while taking advantage of best of breed technologies like Hibernate, Spring, Sitemesh and Quartz to make web application development both fun and easy.

This session will demonstrate how easy it is to get a simple application up and running with almost no effort and then evolve that application by adding features to really show off the power of the Grails framework. Topics include:

• Grails Quick Start
• The Grails Command Line Tools
• GORM and Hibernate
• Groovy Server Pages (GSP)
• Spring Integration
• Unit Testing
• Functional Testing

By Jeff Scott Brown

Grails represents technology that offers great flexibility and power without the complexity introduced by other Java web application frameworks. Custom tag libraries are a snap. GSP Templates provide a simple mechanism for reusing UI elements. Sitemesh is integrated to help provide a consistent presentation across the entire application. Grails provides simple mechanisms for leveraging the power of Ajax.

This session will cover all of these topics to demonstrate how powerful the Grails framework is and show how little effort it takes to build not just a simple toy application but also to build real enterprise web apps.

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.

By Venkat Subramaniam

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

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

This is the year of the dynamic scripting language. Ruby (and Rails) has won the hearts and minds of many independent software developers. JavaScript is experiencing a renaissance thanks to the wild success of AJAX and websites like Google Maps. And Groovy (JSR-241) brings the same level of excitement and "scripting goodness" to the Java platform.

In this presentation, we take a very pragmatic "prove it in code" approach to learning Groovy. Since the syntax is (almost) identical to Java, we can dive right in from the very beginning, learning the "syntactic sugar" as we solve real world problems.

You'll learn how easy it is to install Groovy and get started working with it. You'll tackle file I/O, reading and creating text files. You'll create and parse XML and HTML. You'll interact with databases. You'll create Groovlets (servlets sprinkled with Groovy-dust). And finally, you'll get a brief introduction to Grails (hint: the 'G' is silent).

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

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.

"Which framework should I use?" is the question most often heard on the No Fluff, Just Stuff tour. It's well worth asking. Unfortunately, there is no simple answer. After years on the tour, most speakers have crafted a response that would make any Washington politician proud -- long on style, but essentially, "Well, it depends..."

In this humorous keynote, Scott Davis turns to unconventional sources for enlightenment. Could best-sellers like Blink, Freakonomics, The Tipping Point, The Paradox of Choice, and The Wisdom of Crowds finally solve the puzzle? In this "Da Vinci Code"-like romp through the conventional wisdom of the day, will the Holy Grail of web frameworks be revealed? Probably not, but possible side effects may include nausea, dry mouth, and insight into the eternal question of our industry.

By Scott Davis

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

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.

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.

By David Geary

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.

By David Geary

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.

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.

By Ben Hale

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.

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.

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 :)

The Java 6 (Mustang) release should make your life easier, for a change. It doesn't alter the core language like Java 5 did. It doesn't pack in so many sub-JSRs that you'll be overwhelmed by the amount you have to learn. Instead Java 6 adds several handy things that honestly should have been added before. Among the improvements we'll cover in this fast-paced class:

• A new Console class
• A real Compiler API
• A GIF writer
• Pluggable Locale data
• Access to disk partition size data
• Array reallocation
• Low-level floating point functions
• Reflective access to parameter names
• Access to network interface details
• Pluggable annotation processing
• Improved class file format
• Streaming XML with StAX
• A new Scripting interface

With Sun developing Java 6 in public, you can not only learn about these changes but provide feedback as well.

The classic searchable email archive system is cluged together -- a frankenstein monster combining a relational database with a search engine, with Java just barely able to keep the two together. In this talk we'll demonstrate how email is more content than data, how it's better encoded in XML rather than relational tables, and how Java can convert emails to XML and drive an XQuery backend to produce a simpler and more scalable email archive system.

Attendees should be familiar with XML and have an interest in text search and back-end architecture design.

If we're moving toward Web 2.0, what does that mean for online publishing? In this talk I'll answer that question. Based on my experience as Principal Technologist at Mark Logic working with dozens of the largest online publishers, I'll present a vision for how the Web 2.0 concepts like personalization, collective intelligence, the long tail, and the importance of "owning the data" can and should reshape the face of online publishing -- and how XML, XQuery, and XML-aware text search act as the key enablers. I'll also introduce new Web Publishing 2.0 concepts like "Sweat the content" and "Give answers not links".

(Not content to be a windbag, I'll use practical examples and demos to help get the points across.)

By Jason Hunter

In this talk I'll explain -- without any needless math or boring proofs -- several fun algorithms of interest to back-end web programmers. Each algorithm was selected because it's really practical, really interesting, or both. The algorithms aren't always the same but can include: public key cryptography, credit card checksum validation, TCP Slow Start, two's complement, priority queues, the XOR swap, and the Google MapReduce function for massively distributed calculation.

Attendees need only come with a curiosity about the algorithms that go into the programs we use every day.

Agile practices are popular because they work, but getting people to take that first step can be tricky.

We'll look at how continuous integration was successfully introduced to a very large, established software shop and used to introduce other Agile practices. Let's see what lessons we can draw from this example that you can take back to your shop.

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.

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

Continuous Integration is increasingly recognized as a vital practice in an Agile software shop. Traditionally it's been difficult to set up and administer. Today, that's no longer the case.

We'll look at Cruise Control, a popular CI package. We'll start with the "quick-start" binary release, then change the set up to point to our own project. When we're done, you'll be able to set up your own Cruise Control install on Monday morning.

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.

Hibernate is an open source Object-Relational Mapping Framework that mostly automates the tedious and time-consuming task of persisting Java objects to a relational database. Hibernate is quickly becoming the preferred way for enterprise developers to overcome the object-relational impedance mismatch and a good alternative to the coarse-grained Entity EJBs, low-level raw JDBC, and by-committee specifications like JDO. Learn what your choices in the ORM arena, what to look for in an ORM tool, and how to get started with Hibernate for your next J2SE or J2EE project.

Drools is an open source pure-Java implementation of a forward chaining rules engine. Drools can be used in a J2SE or J2EE application and allows you to express rules programatically or by building domain specific rule languages. Learn how Business Rules with Drools can make your Java applications more flexible and robust.

Software development is expensive, when business rules are hard-coded in your application's source code, changes and additions to those rules translate to wasted time and money. Good object-oriented, component-based approaches can alleviate the burden of keeping up with changes in the business world but they still require that expert knowledge of the changes be passed from the decision makers to the business analysts and finally to programmers that need to implement these changes. Business Rule Engines and Business Rule Languages are based on the basic premise of separation of concerns by empowering business domain experts to express the rules of business in a way that it is directly usable by applications.

Ant has revolutionized the way we build applications in Java and it has become a de facto standard in the Java world. As applications grow in complexity some developers are finding themselves dealing with ever growing and complex builds. Complex builds have to deal with Multiple Operating System, multiple Application Servers, multiple APIs and multiple stages of development.

This talk would highlight some of the growing pains typically encounter in the evolution of an application build system and possible solutions and best practices that can be applied to several of these scenarios. With the arrival of the Ant version 1.6 many of the lessons learned with large projects have been now incorporated. Ant 1.6 can help you deal with complex builds efficiently.

With the explosion of Ruby on Rails and the Java community interest in features like closures and continuations, the Ruby programming language is an excellent one for all developers to know. As the JRuby virtual machine picks up steam, Ruby becomes a must language to understand. The best way to learn Ruby is to see it in action.

In this session, you'll learn the basics of the Ruby language, from a Java developer's perspective from a CTO who has taught and used both languages for production applications. You'll learn:

• The basics of the Ruby programming language, including the object model, collections, and closures.
• Basic metaprogramming techniques that allow Ruby programs to build domain specific languages
• JRuby characteristics that enable you to access Java classes from a Ruby interpreter

When this session is over, you'll have a stronger understanding of Ruby, and where you might put it into practice in your day to day job.

The productivity of Ruby on Rails cannot be denied, but the explosion of Ruby on Rails left many developers, with hard commitments to Java deployment platforms, out in the cold. The continued evolution of JRuby can change that. JRuby is a Ruby implementation on the Java virtual machine. And yes, it runs Rails. In this session, you will learn Rails as it was meant to be learned, within the context of building a live site, from scratch.

We'll take the first hour or so to learn the basics behind Ruby on Rails. You'll see the basics behind each of the model, view, and controller layers. You'll see testing and debugging techniques, as well as the basic mechanics of building a basic web application. Then, learn how you can deploy those applications on Java environments with JRuby. Finally, you'll see some production code used to build a working web site.

The site is built and maintained under unusual circumstances. The team is distributed, with no more than two developers in any one place. The team uses agile techniques such as automated testing, heavy customer involvement, and a SCRUM-like release plan to deliver the core features.

ChangingThePresent was built with extraordinary speed, with a very effective development process. In this session, learn how to use agile techniques and common sense to build great software under high-pressure conditions. You'll learn how a typical day, or week, flows in a team with several high-powered developers. Learn about our core practices:

• How do we do tests?
• How do we manage requirements?
• How do we maintain tight communications with our customer?
• How do we manage the tension between junior and senior developers?

When the session is done, you'll have a better understanding of real techniques used to build a real-world site, and how you can apply them to many development jobs.
