Session Schedule

By Pete Behrens

Are you overrunning your architectural runway? Many companies struggle with their ability to retain their architectural integrity when they transition to agile methods. Emergent Architecture (the other EA) can lead to cowboy coding and ad-hoc design decisions that emerge into a poor overall architecture.

Enterprise Architecture (EA) has been a tried and true approach to address these architectural needs throughout the organization, yet this approach often leads to a heavy-handed, document-rich, control-oriented culture lacking ability to keep pace with today's dynamic business environment.

Attempting to integrate an agile process with an Enterprise Architecture approach can be like mixing oil and water - they just don't work together. This session evaluates alternatives in balancing Agility and EA and proposes an architectural approach to build an Agile Enterprise Architecture into your organization.

This session begins with an evaluation of the strengths of Enterprise Architecture and Agility and various approaches in the industry today that are attempting to balance the two. Enterprise Architecture (EA) means more than technology - it includes business architecture, information architecture, operational architecture, organizational architecture, technical architecture and infrastructure architecture. There are many EA models available today including the Zachmann Framework, McGovern/Stevens Model, and the Federal Enterprise Architecture (FEA) framework just to name a few. Each of these frameworks provides a valuable perspective on EA, but all of them depend on your organization to exe

Business leaders and stakeholders require accountability and accuracy in our software release projections and yet, as an industry, we have failed. However, many of these same leaders are not convinced that agile is any more than an excuse to avoid projections at all. While it is true that agility provides the framework to support change, it doesn't mean you can't provide accurate projections. In fact, a well-executed agile process actually provides more accurate results with less time investment than traditional methods. This session will demonstrate these agile project management techniques to manage 6-12 month projects.

This session focuses on the release level, followed by Part II which focuses on the sprint level.

In this session we will demonstrate an engaging agile team estimation technique to drive more accurate projections than traditional estimation techniques provide. Then we will explore multi-level planning and tracking practices to guide your understanding of how to use those estimates to manage your release goals.

By Pete Behrens

"YAGNI (You Ain't Gonna Need It)" and "Doing the simplest thing possible" are mantras of agile development. A white board, sticky notes, and flip chart paper are by far the best tools for individual teams. However, when coordinating work across 10 - 50 teams across 12 time zones, more tooling is required. Learn how agile enterprises are leveraging tooling to manage their portfolios, projects and products.

Teams are often distributed, offshore and dependent on other teams which require assistance to effectively manage. Furthermore, IT governance requires additional oversight in project and portfolio management for tracking investments, return on investments and reporting status to the business and other executive stakeholders. This session walks through various phases of the agile software lifecycle and provides tooling examples used to help facilitate each phase. Examples from two 300+ agile development organizations will be referenced to provide a context for the discussion. Specific agile project management tools discussed include VersionOne, Rally and Microsoft Team System, ScrumWorks, Co

By Pete Behrens

Are you being asked to measure your agility? How productive is your team? What is the quality of your product? How accurate are your estimates? Be careful, you will get what you measure.

This session will evaluate metrics which attempt to measure productivity, quality, esimation accuracy, value, and return on investment within the context of an agile project. What measurements are teams using and why? We will explore various measurements used by session participants and discuss some of their pros and cons.

We will discuss the pros and cons of various metrics and how each has the potential to create dysfunction within the team and how they can be "gamed".

By Scott Davis

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 te

By Scott Davis

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

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? Thes

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.

By Ben Hale

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.

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

Is someone asking you to lead an agile project? There are many how to books for agile methods, but the coverage of skills and techniques for leading are a bit on the light side. Whether you are a manager, tech lead, or a non-stop inspiration for your fellow developers, this session will provide you with new insights into the how and whys associated with coaching / leading an agile project or an agile transition.

This session will focus on the skills and tasks that help agile projects succeed and last. Topics covered will range from coaching to communication to tracking to addressing problems and problem people and more.

By Howard Lewis Ship

Part one (of two) covers the TestNG unit testing framework, and shows how it integrates with Selenium (for integration testing).

In part one of this two part session, we'll discuss the basics of unit testing and show how to use TestNG. We'll discuss how to use the tool, organize tests, and collect results, as well as integrate with IDEs, Ant and Maven. Lastly, we'll see advanced uses of TestNG combined with Selenium to automate integration testing within a test suite.

By Howard Lewis Ship

In part two (of two) we go in depth on EasyMock, the weird and wonderful tool for creating mock objects on the fly. We'll do a good bit of live coding as we examine how to use, tame and extend this powerful tool.

Unit testing with 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 weird 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 be doing some live coding to show you step-by-step how to build up a unit test, interpret EasyMock's baffling error messages, and set yourself up for easy reuse of testing code.

By Howard Lewis Ship

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 U

By Howard Lewis Ship

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

Mustang, the Java6 release, is out, and even if you're not looking to adopt the new platform right away, it's important to know what's there so you can start to plan for it. In this presentation, we'll go over the major new features of the Java6 platform, including the new integrated XML services capabilities (JAX-WS and JAXB), dynamic/scripting language support (javax.script), new JVM "attach" capabilities, new annotations supported by the javac compiler, and more.

For an audience comfortable with some prior Java experience, preferably familiar with Java5.

By Ted Neward

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 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.

By Ted Neward

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.

By Ted Neward

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 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".

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.

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.

By Jared Richardson

A great team builds great software, but how do you build a great team?

Let's move beyond getting lucky and look at some key practices that will help you build your scattered cats into a well-oiled machine.

By Jared Richardson

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

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.

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.

To most software developers, the command line is the pinnacle of interface design however, most users find this approach a little lacking. Despite a lack of training, many software engineers are called upon to create user interfaces that won't cause their users to grab the pitchforks. In ninety minutes, you'll have the tools to build compelling interfaces.

Seemingly overnight, Ajax has gone from an obscure acronym to, well, having conferences devoted to it. People are often surprised when they learn that Ajax isn't really anything new - so if it's yesterday's technology, why all the hype? This talk will examine the course of events that led up to the current love affair with richer client applications. We'll talk examine the technologies that power an Ajax application and discuss how to work with them - and then we'll examine a number of frameworks that will do much of the heavy lifting for us!

Once we understand the techniques of Ajax, we'll touch on where (and where not) it's appropriate for your application finishing off with some common gotchas.

By Nathaniel Schutta

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.

There is a shift going on in the Enterprise. While still used and useful, the promises of the SOAP/WSDL/UDDI Service-Oriented Architecture (SOA) stack have failed to live up to their promise. A new vision of linked information is enveloping online and Enterprise users. The REST architectural style is squarely behind this thinking as a way of achieving low-cost, flexible integration, increased data security, greater scalability and long-term migration strategies.

If you have dismissed REST as a toy or are unfamiliar with it, you owe it to yourself to see what is so interesting about this way of doing things.

There is tremendous interest in REpresentational State Transfer (REST) as an architectural style for building scalable, flexible, information-driven architectures in the Enterprise. The success of the Web has caught our attention in the face of increased complexity and many failures with more traditional Web Services technologies. The problem is that it is difficult to sell a way to do things. Managers do not want to feel like they are innovating in the middleware space. They want to understand why they should deviate from the blue prints laid down by the industry leaders. They want to understand when they should use REST, when they should use SOAP and when they might fallback to regular old

By Brian Sletten

Imagine the simplicity of REST married to the power of Unix pipes with the benefits of a loosely-coupled, logically-layered architecture. If that is hard to imagine, it may because the architectures available to you today are convoluted accretions of mismatched technologies, languages, abstractions and data models.

NetKernel is a disruptive technology that changes the game. It has been quietly gaining mind share in the past several years; people who are exposed to it don't want to go back to the tired and blue conventions of J2EE and .NET. Not only does it make building the kinds of systems you are building today easier, it does it more efficiently, with less code and a far more scalable runway to allow you to take advantage of the emerging multi-core, multi-CPU hardware that is coming our way.

Come see how this open source / commercial product can change the way you think about building software.

NetKernel makes the things you are doing now easier, but also makes new types of systems possible. A wise man once said, "XML is like lye. It is very useful, but humans shouldn't touch it." If you've had to incorporate XML into your project by hand, you have probably been burned by getting too close. NetKernel turns this wisdom on its head and encourages you to use XML like the liquid data stream you want it to be. But, XML is only part of the story. Resource-oriented computing is a generalized and revolutionary approach to modern, flexible systems. There is less code to write, but it is more fun to do. Orchestration of existing services and data sources is faster, easier and more encompas

Ok, I can't promise you profit, but hopefully you'll have fun. Maven 2 introduces a number of new features (including that performance feature) that make it a swell project management tool for development.

Come hear about how we can abuse Maven to manage distributed deployment scenarios before the Modules JSR is done.

This talk will introduce Maven 2 and what it has to offer as a team-oriented development and project management tool. Then we will take a strange turn and discuss how the MavenEmbedder API can be used as a lightweight, low-admin deployment mechanism for self-updating, distributed Java installations. This is a very example-driven talk. We'll look at lots of code but you'll be able to walk away with a fresh take on how to roll out a new versions of entire applications, bug fixes, security patches or new features with very little effort.

By Brian Sletten

Ever since we started doing relational joins, we've looked for ways to tie data together. The web has given us no end of new data sources to integrate but it seems like the best we can come up with is locating Starbucks on Google Maps. The problem with browser-based mashups is that they don't survive the session, we have no way of referring to the results in future queries and ultimately we don't maintain ownership or control of the process.

We want control of our data and our mashup results. We want ever more ways to view, explore and requery them in multi-faceted ways. Do you know what your data integration strategy is for the next few years? Are you sure? You owe it to yourself to come find out.

The good news is that a slew of emerging technologies are starting to make this happen. Come explore integration strategies that allow real mashups to function on both the web and the Enterprise. We can use a variety of languages and tools to link legacy data and modern content sources. We will explore resource-oriented computing as a new way of building systems that manage information spaces, not code. We will discuss the benefits and deficiencies of XML in this space as well as look at things like JSON, RSS and RDF. We will look at research projects like Simile from MIT, metadata storage systems like Mulgara and scalable orchestration environments like NetKernel. What happens when you mix

Most people new to Aspect-Oriented Programming (AOP) are fed up with separation of concerns zealots explaining how great their techniques are at dealing with... logging. Ok, you get it. Logging is a cross-cutting concern that can be appropriately modularized. What else does AOP have to offer? A lot, it turns out. This talk will give an introduction to the motivations of AOP as well as a series of concrete examples drawn from enterprise and client side Java. Come learn how AspectJ-flavored AOP can begin to benefit you immediately either in development or production environments. Learn how to enforce architectural policies, find Swing threading issues, reduce the invasiveness of the Observer design pattern or even improve the reusability of your domain models. Now that Spring 2.0 provides support for AspectJ, the time has never been better to learn about these new (but backwards compatible) ways of thinking about building software.

Attendees will learn about The history and reasons behind AOP Development-oriented aspects that can be useful, but compiled out of production code Production-oriented aspects that can simplify development and ease the burden of future changes Basic AspectJ usage and jargon How to use AspectJ with Spring Rating: Intermediate Category: Architecture/Languages, Client Side Java, Server Side Java Prerequisites: Basic Java. Some level of AOP understanding is helpful, but not required. The pace of the introduction will depend on the average level of exposure the audience has previously had to AOP.

By Brian Sletten

Software engineers are usually familiar with the notion of scheduled tasks and cron jobs at the OS level. Quartz is a relatively new open source Java API for scheduling jobs in your applications or Enterprise.

The Quartz API grew out of the Open Symphony project into a powerful way to schedule jobs in the Enterprise. It can easily be embedded in your client side applications or clustered on the server side for participation in JTA transactions. This talk will be an example-driven walk through beginning with the basic features and ending with large-scale clustered and standalone job engine servers backed by databases. This talk should be accessible to anyone interested in a job scheduling engine.

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.

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.

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.

Object-oriented scripting languages, or agile dynamic languages, as some like to call those, are gaining programmers' attention. Several dynamic languages are on the JVM. Groovy and JRuby are two languages that are drawing developers' interest. Sun has shown support for these two, and especially JRuby by hiring the core developers.

In this session we will learn what JRuby 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 JRuby. In addition to the current features, we will also discuss the state of the language and tools.

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

You have worked on software projects with varying degree of success. What were the reasons for the success of your last project? What were the reasons for those that failed? A number of issues contribute to project success - some non-technical in nature. In this presentation the speaker will share with you practices in a number of areas including coding, developer attitude, debugging, and feedback. The discussions are based on the book with the same title as the talk.

In this session you will learn about practices beyond what well know methodologies prescribe. While we reemphasize some popular practices, we will also discuss other often overlooked, but important practices - practices that contribute to success of projects.

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.

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

Ajax applications have unique design and architectural challenges and opportunities. This presentation will show you how to take advantage of the Ajax's strengths, and work around its quirks.

We'll start with an overview of Ajax, and then dive right into an extended example where we add Ajax to an existing web application. Along the way we'll cover several tools that we use to aid in Ajax development: The JavaScript Shell, Firebug, and the Web Developer's Toolbar. We'll also look at two popular JavaScript Ajax libraries: Prototype and Scriptaculous. With the example application under our belts, we'll move to a discussion of Ajax architectural questions, including: How do I select an Ajax library? What format data should my Ajax calls use: XML, JSON, HTML, or other? How do I handle the back button and deep linking in Ajax? Prior exposure to Ajax and JavaScript is useful but

With the sudden importance of Ajax, it's time to take JavaScript seriously. That means learning it the right way: looking at the fundamentals of the language and surveying its strengths and weaknesses, instead of just copying other people's poorly written examples.

JavaScript got a bum rap. It's almost universally derided among serious programmers for being a toy language, or for its strange characteristics, or bugs, or slowness, or because it's only good for adding useless window dressing to web pages. But JavaScript is actually a very nice little language which is popping up everywhere these days (not just in Ajax apps). Sure, JavaScript is quirky, but its problems are mostly due to history, association, and misunderstanding. Especially misunderstanding. Let's face it: most developers learned JavaScript by looking at examples in web pages they found online, and few of those examples are paragons of JavaScript style. Other developers learned JavaScr

By Glenn Vanderburg

Building on part 1, this talk dives deep into JavaScript's object model. We'll see how it differs from more mainstream object-oriented languages, and why. We'll explore how to hide some of those differences, as well as the reasons you might not want to. Additionally, we'll cover useful tools for JavaScript testing, debugging, and profiling.

Ajax is not the focus of this talk, but a strong foundation in JavaScript is essential for working with Ajax.

The early years of computers -- the '50s and '60s -- were characterized by furious exploration of a huge variety of different ideas. Since then many of the hot topics of those days have moved to the fringe, largely ignored by the mainstream of software development. But some of them are being rediscovered, and a lot of what we think of as "new developments" are really just some old ideas returning to center stage.

This talk will trace the roots of some contemporary software trends back to their origins before most of us were born.

Performance myths about the Java platform abound, from the general "Java is slow", to the more specific "reflection is slow", "allocation is slow", "synchronization is slow", "garbage collection is slow", etc. Many of these myths have their root in fact (in JDK 1.0, everything was slow); today, not only are many of these statements not true, but Java performance has surpassed that of C in many areas, such as memory management.

In this class, we'll look at some common Java performance myths, identify where they came from, and explore the platform changes that have rendered them no longer true. Many common performance hacks don't actually help, and some can seriously hurt performance. The result is that clean code that follows common usage patterns generally shows far better behavior on modern JVMs than code laden with tweaks designed to "help" the JIT or garbage collector. More often than not, this well-intentioned assistance has the unfortunate effect of undermining many common JIT optimizations, resulting in slower -- not faster -- code.
