Mark Twain once said, "Everyone talks about the weather, but nobody does anything about it." Do you feel the same way about Unit Testing? Are you actively testing your code, or are you just thinking about testing your code... some day... once you get some more free time...

Unit testing offers benefits beyond the obvious. A happy side effect of writing unit tests is that your code ends up being better architected. By forcing you to be a consumer of your own code outside of the context of the main application, you end up seeing your code in a different light. Hidden dependencies get flushed out early. Good unit tests force your code to be more loosely coupled and highly cohesive.

This presentation is a survey of the testing ecosystem. A good testing infrastructure should include more than just JUnit. Cobertura, a test coverage tool, shows you how much of your code base is being tested. Writing test cases in Groovy adds a measure of flexibility that makes working with XML (and string data in general) a piece of cake. EasyMock allows you to test interfaces instead of implementations (and also avoid having to hand-code and maintain your own mock objects). We'll also look at functional testing libraries like HttpUnit, DbUnit, and JUnitPerf that allow you to test how your code behaves out in the wild, interacting with real subsystems instead of just mocks.

Most importantly, you'll see these tools live in action -- real code examples instead a simple slideware overview. Rather than looking at each tool in isolation, you'll see how they interact and complement each other. Rather than just talking about testing, we'll (finally) do something about it.

In this talk, we'll survey the web services exposed by leading websites (Google, Yahoo, Amazon, eBay) and discuss how they are driving the AJAX revolution. You'll see examples of RESTful, SOAP, and JSON web services, as well as the strengths and weaknesses of each.

Everyone seems to be talking about AJAX and Web 2.0 these days. While the UIs of AJAX-enabled websites such as Google Maps and Flickr are undeniably cool, they wouldn't exist without a strong SOA/Web Services infrastructure behind the scenes.

"Web Services" is an overloaded term. While SOAP is a mainstay in the web services world, there are other equally valid flavors (REST, JSON) that accomplish the same goal -- decoupling the data from the presentation layer, the platform, and even the programming language used.

Rather than talking about web services in the abstract, this talk shows examples of each flavor of web services as it is used in the wild by leading web companies. They have all taken slightly different approaches to the same problem. We'll compare and contrast their public-facing offerings.

There is no one "right way" to expose your API via web services. After this talk, you should have a better idea of the relative strengths and weaknesses of each variant.

How do you get started with an Agile development methodology? Everyone has been talking about eXtreme Programming for years, but how do you get it introduced to your team? Many times, you're not simply transitioning from from one methodology to another -- you're introducing a methodology for the first time. Adding structure to a previously unstructured endeavor. Adding a touch of discipline where programmers once roamed free.

This presentation talks about how to introduce Agile practices slowly. Think of it as refactoring your team iteratively. If you drop 25 new "best practices" on developers all at once, the chances of getting any of them to stick is slim. If you start with one practice and get buy-in on it, sneaking in the next one (especially if it is complementary) is far easier.

• starting with source control
• easing into iterations with XPlanner
• is your team ready for pair programming?
• writing your first unit tests
• evaluating your code base for unit test coverage

The Spring framework is one of the fastest growing open source frameworks. New job postings are gaining rapidly, and many customers are adopting Spring instead of heavier alternatives. In this session, we’ll introduce Spring. You’ll see how Spring can give you much of the power of EJB, without the complexity or pain.



Spring uses concepts like dependency injection and aspect oriented programming to ease standard enterprise development. Spring developers write plain, ordinary Java objects (POJOs), instead of sophisticated components. In this session, you’ll see a basic Spring application. You’ll also see some details about some of the enterprise integration strategies, including:

• Spring AOP
• Transactions
• Persistence
• Model/view/controller

When the session is over, you won’t be an expert, but you should have a much clearer understanding of what Spring does, what it doesn’t do, and why it’s growing so rapidly.

By Stuart Halloway
Dependency Injection (DI) is the cornerstone of Spring. The core concept is quite simple, but (surprise!) actual practice can become complex. To take full advantage of Spring DI, you need to understand not only the basics on configuration, but also the container lifecycle model and the various hooks provided by the framework.

Topics will include

• The difference between DI and Continuous Integration


• Setter Injection


• Constructor Injection


• Factory Injection


• Bean lifecycle


• Method Injection


• Using the ApplicationContext


• Custom PropertyEditors

By Stuart Halloway
Spring offers developers a simpler, more robust method for configuring applications. These benefits extend to security through the ACEGI framework. ACEGI makes the otherwise daunting task of securing your application logical and straightforward. More importantly, through its support for single sign-on provision through Yale's CAS system and its ability to provide instance-level authorization, Spring extends the common security model of most J2EE apps beyond what they are traditionally capable of.

In this session, we'll explore:

• configuring ACEGI to authorize against an in-memory user list, a database, and a JAAS login module
• page level authorization
• method level authorization
• instance level authorization
• forcing HTTPS connections to secured sites
• impersonation using the RunAsManager

By Stuart Halloway
Ajax applications have unique 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 not required.

By Stuart Halloway
This presentation covers JavaScript from the perspective of a Java programmer. We assume that you may be using an Ajax toolkit, but still need to be able to read, modify, and test the JavaScript code in your application. You will learn the common idioms of JavaScript by looking at working code from Prototype and Scriptaculous.

All Ajax programmers need to know JavaScript. Toolkits will do some of the work for you, but your own JavaScript will differentiate your applications from others. A reading knowledge of JavaScript is also necessary when selecting an Ajax framework, and for testing and debugging applications.

We'll go straight to the interesting parts of JavaScript programming:

• Prototype-based inheritance


• Functional style


• Dynamic evaluation


• In-browser testing

We'll demonstrate these concepts using the popular Ajax frameworks Prototype and script.aculo.us.

By Stuart Halloway
Hibernate is easy to get started with, but can sometimes be hard to make efficient or secure. In fact, the default settings for Hibernate createapplications that will run slowly, cause unwanted round trips to the database, and may be more restrictive and/or permissive from a security standpointthan you would otherwise want.



This session will show advanced techniques for tuning performance, including:
• advanced collection mapping strategies
• lazy loading
• cascading update management
• lifecycle management
• Hibernate's interceptor layer
In addition, we'll examine the security considerations when using Hibernate. Often, single-credential data access isn't enough for sensitive data. We'll
walk through using per-user credentials for data access, logging security information about and through Hibernate, and accessing data sources through secure application servers.

By Stuart Halloway
Learn to use Spring AOP, aspect injection. and AspectJ integration

Spring provides powerful support for Aspect-Oriented Programming (AOP), via

• Spring Advisors


• Dependency Injection for Aspects


• Integration with AspectJ

In this session you will learn to use Spring AOP in real-world settings. We'll start with the basics of programmatic pointcuts, advice, and joint points. Then, we'll integrate these into the application Spring-style, using Dependency Injection.

With the basics out of the way, we'll move to meatier questions, including:

• How (and when) should I step up to AspectJ?


• How are Aspects implemented, and what are the performance implications?


• What are the alternatives to Aspects?

Attendees will get more out of this presentation if they have a basic knowledge of Spring and Dependency Injection.

It has been said that Grails is the addiction and Groovy is the drug. If you want to start building slick web applications rapidly with Grails it helps to start with a solid understanding of the Groovy language itself.

It has been said that Grails is the addiction and Groovy is the drug. If you want to start building slick web applications rapidly with Grails it helps to start with a solid understanding of the Groovy language itself. In this session, we'll go over the basics of the language by focusing on the core of Groovy. We'll look at Groovy collections, Groovy's interaction with Java, creating Classes in Groovy, Groovy's MOP and much much more. By the end, you'll be a Groovy expert ready to embrace all the language has to offer.

By Andrew Glover
What makes Groovy particularly appealing with respect to other
scripting platforms is its seamless integration with the Java platform. Because it's based on the Java language (unlike other alternate languages for the JRE, which tend to be based on earlier predecessors), Groovy presents an incredibly short learning curve for the Java developer. And once that learning curve has straightened out, Groovy can offer an unparalleled rapid development platform.

And once that learning curve has straightened out, Groovy can offer an unparalleled rapid development platform.

The secret to Groovy's success, in this regard, is its syntax, which is Java syntax, but with far fewer rules. For example, Groovy doesn't require semicolons, and it makes variable types and access modifiers optional. Moreover, Groovy makes use of the standard Java libraries you're already familiar with, including Collections and File/IO.
And, finally, you can utilize any Java library from within Groovy, including JUnit.

The fact is, Groovy's relaxed Java-like syntax, its reuse of standard Java libraries, and its rapid build-and-run cycle make it an ideal candidate for rapidly developing unit tests. But don't just take my word for it; let's see it in code!

In the years since JUnit’s introduction, a number of frameworks have been built to enhance its utility for testing and validating XML, controlling the state of a database, testing legacy code, performance testing, and functional web testing.

Developer testing has arguably become an industry expectation due to the immediate positive affects testing code early has on software quality. It’s no surprise that Java’s JUnit framework has become the de facto standard for developer testing. In the years since JUnit’s introduction, a number of frameworks have been built to enhance its utility for testing and validating XML, controlling the state of a database, testing legacy code, performance testing, and functional web testing. In this session we’ll take a look at XMLUnit for testing XML related code, DbUnit for testing code which depends on a database, JUnit-addons for testing private methods, JUnitPerf for load and performance testing, and JWebUnit for functional web and user acceptance testing. We’ll also examine the extensibility of these frameworks in an effort to combine them into handy aggregate frameworks for performance testing of database code, scenario testing of web sites, and any other combinations we can cook up.

By Andrew Glover
No one will argue that JUnit has positively affected the quality of thousands of Java applications around the world. JUnit’s simplicity and ease of use ushered in a whole new era of code quality; however, as many developers have found, its simplicity has also limited its use. TestNG was designed from the ground up to overcome some of JUnit’s limitations; moreover, TestNG’s features make it a great tool to complement your JUnit tests.

In this session we’ll learn about TestNG’s flexible fixture model, its test categorization capability, dependent methods, and TestNG’s powerful parametric testing facility. We’ll also see how both TestNG and JUnit can play together in a build process.

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 encompassing than with more conventional technologies.

This talk will help explain what NetKernel is (app server? pipeline tool? embedded SOA?) and, through a comprehensive set of examples, give you a glimpse at a deeper software reality than you might have thought possible.

Disclaimer: There will be no blue pills given to you to make you forget what you have seen. Come with an open mind.

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

Just about every modern software developer has a copy of the Gang of Four "Design Patterns" book sitting on a shelf; many of them have actually read it. The dark secret of the patterns community is that there is often a large gulf between whiteboard simplicity and real-world complexity. Language choice plays a part in the design (and even importance) of patterns. The situation is made even more confusing by the fact that many of the core patterns have now been "voted off the island" for one reason or another. This talk will give a pragmatic overview of the motivations behind design patterns and will focus on applying a handful of the GOF patterns to example scenarios in Java, Ruby and C#. A quick introduction to the role AOP plays in changing the patterns landscape will also be covered.

Attendees will learn about
The benefits and history of patterns in software
How language choice affects pattern implementations
Applying a handful of GOF patterns in code examples
Why there is no DP4J available

Agile programming is a collection of core principles and techniques that allow software developers to create lighter, more responsive applications, and to have fun doing it. Many established organizations are either openly or sub-conciously hostile to many of the principles of Agile development.

We'll explore the intersection of these new practices and old-world sensibilities, relying on real-world case studies to illustrate some of the compromises that are necessary to bridge the gap. In addition to technical and process aspects, we'll also spend some time talking about the business aspects, such as how Agile development affects contracts.

This session will help a Java developer choose a persistence framework. After the session, you will
• Understand the core strengths and weaknesses of the main persistence frameworks in the Java space
• Understand where marketing influences can impact persistence
• Know what’s going on behind the scenes to impact the persistence pictures
• Answer questions about persistence frameworks that might not be mainstream


This free-form session is intended to help attendees choose or validate a persistence framework. In it, the instructor will take questions from the audience, and tailor the session to the questions asked. Bruce will focus on three persistence frameworks: EJB, JDO and Hibernate. He’ll talk about the evolution of each of the frameworks. He’ll talk about the fundamental design philosophies of each, and what makes each unique and strong.

But understanding technical strengths is not enough in the area of persistence. To make the best possible choice, a developer or architect must also understand the politics of persistence, and the marketing pressures that lead to the success or failure of each framework. The proposed common standard across JDO and EJB will get special consideration.

This format has been very popular among nofluffjuststuff attendees. It’s highly tailored to each audience, but still flows with good structure. When the session is over, you’ll have a better understanding of the major persistence frameworks in the Java space, and what makes each valuable. You’ll also understand how much of a role market share and technology play in the success or failure of a persistence framework.

By Bruce Tate
O/RM (Object/Relational Mapping) seeks to eliminate repetitive or tedious work enabling the CRUD (create, read, update, delete) that underlies most applications. Hibernate is a popular, open-source O/RM tool that uses reflection (instead of code generation, like EJB, or bytecode injection, like JDO) to manage your persistence layer.

This session will introduce you to Hibernate. After an overview of common usage scenarios, including web and enterprise applications, we'll examine the basics of getting Hibernate running. We'll cover the mapping file format and syntax, including common relational mapping structures. Then, we'll examine the Hibernate API for interacting with the framework. Finally, we'll cover the common architectural decisions you'll have to make as you include this (or any other) O/RM framework.

In this session, we'll review the new features of Spring 2.0. If you've been using Spring 1.x, you'll want to hear about the improvements.

This material comes directly from Interface21. The SpringFramework version 2.0 brings tremendous maturity to one of the most successful Java projects of our time. In this session, you'll see

- Radical improvements in the simplicity of context definitions
- Much better AspectJ integration
- Unified user interface strategies, and the continued emergence of WebFlow.

By Bruce Tate
The state of the art is progressing rapidly, and dynamic languages are driving the revolution. Find out about these topics that will be central to programming. We'll discuss continuation servers, metaprogramming frameworks and functional langauges.

Seaside provides a much richer web development experience than you can find in Java today. Learn how continuations can radically improve your web development experience, and learn what Java frameworks are doing about it.

The programming world is abuzz over the Rails framework, but how many of the ideas are exclusive to Rails? We'll look at Active Record, and discover the fundamental innovations that let it happen. What improvements might be made by Java persistence frameworks, and where does Active Record come up short?

Concurrent programming will come to a head with the introduction of multiprocessor systems. We'll discover just how broken conventional langauges are. Also, see how functional languages solve this problem.

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
In 2005, JSF hit its stride, as evidenced from overwhelming support from both vendors and the open-source community. JSF 1.0 had plenty of holes, but open-source projects have arisen to address those needs. This session takes a look at three of those projects: Tomahawk (MyFaces component library) FaceletsSeam

MyFaces is an open-source implementation of the JSF spec. In addition, MyFaces developers got a little carried away and also developed a useful set of custom components that you can use in your own applications, regardless of whether you use MyFaces as your JSF implementation. Those components are now packaged separately from MyFaces under the name Tomahawk.

Facelets is an open-source project from java.net that lets you implement views with Tapestry-like HTML pages. That technique is a powerful feature that lets graphic designers and software developers work separately in parallel.

Seam is a framework from JBoss that provides a component model that unifies the EJB and JSF component models. Seam makes great use of annotations to meld EJBs and JSF components in a seamless fashion (thus the name).

Lots is happening in the JSF space. Come to this talk and learn about these three exciting open-source projects.

By David Geary
JavaServer Faces is a well designed user interface framework, but it lacks a number of features you might otherwise expect out of the box; for example, JSF does not explicitly provide support for client-side validation.

So, from the folks that brought you Struts, comes Shale, a collection of useful enhancements to JSF. A top-level Apache Software Foundation project, Shale adds some really cool features to vanilla JSF, including:

Web flow: script dialog flow
Remote Method Calls: easily call JavaBean methods from JavaScript
Tapestry-like views: code views in pure HTML
Use Apache Commons Validator validators on the client or server, or both
JSF testing framework: mocks for easy JSF testing

There's a lot of cool stuff in Shale that makes JSF a much more compelling proposition. Come see what it's all about.

This is a code-intensive, fast-paced look at Apache Shale. Forty-plus slides and five demos makes for an action packed session that illustrates the cool features that Shale provides.

By David Geary
User interfaces are usually the most turbulent aspect of an application during development. Constant tinkering with the UI means constant changes to your code, so as a UI developer, you want to minimize the scope and effects of those code changes.

Open-source Java provides two powerful software packages that help you manage UI complexity: Tiles and Sitemesh. Tiles composes webpages from discrete regions of your user interface known as tiles. A tile contains a JSP page for layout and one or more JSP pages for content. Sitemesh decorates webpages with decorators that can be associated with URL patterns. Once you set up your decorators, you can decorate pages that match a decorator's URL pattern.

Come see how to use Tiles and Sitemesh with a guided tour from the inventor of Tiles, who has recently become a Sitemesh believer.

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

Come to this exciting preview of one of the leading web application framework contenders with the potential to be the Next Big Thing: Ruby on Rails. An innovative framework with an eye-popping array of ultra-cool features such as active record and native support for Ajax, Rails greatly simplifies web application development and puts the joy back in software development. Rails is easy, fun, and very productive; in fact, in the throes of Rails-mania, some converts have claimed that developing with Rails is at least 10 times as fast as your favorite Java framework. Could that be? Come see for yourself.

At about the same time Java was brewing, another language from the far east entered the landscape with hardly any notice. Carefully crafted by Japanese devotees, Ruby, a potent mix of SmallTalk, Python, and Perl, toiled in relative obscurity as the marketplace moved in droves to Java.

Today we have J2EE, the 800-pound gorilla of enterprise development. That 800 pounds cuts both ways: J2EE is powerful, but it's a complicated beast with a long and steep learning curve that sports a dissying array of peripheral open-source software. And J2EE has many design compromises and idiosyncrasies that reflect it's growth and evolution. Some J2EE developers have begun to wonder if there's a better way...

Is Service Oriented Architecture the next wave of distributed computing or just the same old crap in a shiny new package? This session provides an overview of what most people agree is the definition of SOA. I talk about SOA, ESB, CORBA, your MOM, and a bunch of other acronyms.

This session is a pragmatic look at SOA from a developer perspective, including such (never talked about) topics like tranports, granularity, versioning services, transformations, and whether you should be doing this or not. I show lots of slides with diagrams and talk about how to evolve towards an SOA. SOA can work if you ignore the hype and focus on the real meat: building loosely coupled message-based applications. This session discusses just that.

This session discusses techniques and tools for debugging enterprise applications (without using System.out.println()!)

It's an interesting dilemma – we have the best tools for software development ever, yet developers are still debugging enterprise applications using ystem.out.println()! This session discusses techniques and tools for debugging enterprise applications. It shows how to perform remote debugging through all the major IDEs, either on the same machine or across a network. It also shows how to debug using the command-line jdb debugger (the only one guaranteed to always be available).This session shows how to debug web, EJB, and lightweight enterprise applications. It discusses class loaders, interactive enterprise debugging with Groovy, and how to automate repetitive tasks using JWebUnit and Selenium, making the computer do work for you instead of vice versa (how many times do you have to walk multiple pages through a web application to get to the point where you can debug it?). This session shows you how to automate these and other common debugging tasks. The goal is to make hunting and eliminating bugs in complex applications much easier.

Key Session Points:
• Setting up remote debugging in IDE's
   o Eclipse
   o IntelliJ
• Effective remote debugging
• When it's all you've got: jdb and enterprise applications
• Forensic debugging using loggers
• Debugging web applications
   o Inspector
   o Bookmarklets
• Debugging EJB
• Debugging in lightweight frameworks
• Interactive Debugging with Groovy
• Automating debugging tasks
   o JWebUnit
   o Selenium

This session shows how to use Java as the building block for domain-specific languages. It discusses the next revolution in programming: language-oriented programming and the nascent tools that support it.

If you look at the way advanced programmers in highly dynamic languages (like Lisp, Smalltalk, Ruby, etc.) work, they tend to build domain specific languages on top of their low-level language. The language syntax itself becomes building blocks for languages that are highly specific to their problem domain. It’s not as easy to apply this technique to a static language (like Java), but it is possible. This session shows how to use Java as the building block for domain-specific languages. It discusses internal and external DSLs, with pros and cons for each. This session progresses from creating an internal DSL using Java syntactic elements as keywords through using compiler-building tools to create your own external DSL arriving ultimately at the new tools that allow you to build, edit, and deploy external DSL (language workbenches). This session covers the theory and practice of building DSL's and why this is an important step in the evolution of programming paradigm.

Too often, Swing applications are slow, ugly, and hard-to-maintain. It turns out that it doesn't have to be this way. Swing can be used to create highly-responsive, beautiful applications that are very maintainable. If this isn't consistent with your own experience, don't feel bad; its not very obvious how to make Swing sing.



In this session, I explore three topics that lead to much better Swing applications:

- Proper Swing threading
- High-quality third-party Swing look-and-feels
- Good practices for coding Swing applications

In the threading portion of the session, I explain Swing's event handling architecture and its implications for Swing applications. Understanding this topic is crucial to creating highly-responsive Swing apps. I demonstrate how to use this knowledge in the form of many live-coded examples, and I show how frameworks like SwingWorker and FoxTrot can make this easier. Java's default look-and-feel, Metal, is awful (and in my opinion, the "Ocean" theme in JDK 5.0 doesn't do enough to improve it); you should stop using it immediately. But creating good-looking applications is sadly more than slapping in a look-and-feel; you must also take care to understand the principles behind attractive layouts. I spend the second part of this session exploring how to make your Swing applications look great through a combination of third-party look-and-feels and layout techniques.

Rich client application development using Java can be intimidating giving the vast flexibility in application design and structure. It also can be frustrating to create the large number of support services (persistence, menus, event and job frameworks) that a large scale rich client applications needs. The Eclipse Rich Client Platform is one project attempting to solve these issues by providing a core infrastructure that not only provides the day to day services a rich client application developer needs, but also providing a suggested path to guide you down the road of designing your application. This presentation introduces both the Eclipse RCP and the tools provided by the Eclipse IDE that assist developers in writing RCP apps.

Today's users are beginning to demand richer and richer application experiences. Plain html pages simply don't cut it anymore. Applications like Google Maps (Ajax) and Yahoo Maps (Flash) show how the UI experience can be pushed to the next level. As an IT manager, how do you decide which route to take however? Should you use Ajax because it is the new "it" technology. Is Flash a viable option with its 95%+ browser availability? Perhaps Java deployed through web start is really the best choice in contrast to what the buzz would lead you to believe. This presentation takes a look at these three core rich client technologies from both deployment/user experience and ease of development perspectives.

Have you wasted time writing lots of security-based code and ever wondered if there's a
better way to add security to your application? Are you confused by declarative security?
Have you read about JAAS (Java Authentication and Authorization Service) but wondered where
it fits? Have you ever said, "Can I just see a working example"? If so, then this talk is for you.

If you're looking to restrict access to resources based on user roles, then J2EE declarative
security is for you. You'll learn how to protect web pages and business logic without adding
a single line of Java code to your business logic.

This presentation covers:


* J2EE Security Overview
* Web-based Security
* Protecting Access to Web-based Resources
* JAAS Overview
* Integrating JAAS with J2EE Security
* Configuring JAAS with JBoss and Tomcat
* Using Programmatic Security
* Integrating web-based security with business logic



We use Ant and XDoclet to deploy a simple J2EE-based web site using JSPs, Servlets, and EJBs.
We will secure the application in an iterative style. We use JBoss as the reference implementation,
but the core techniques shown here are applicable to any J2EE 1.4 application server.


Intended audience: Experienced Java/J2EE developers

You've used EJB in the past and been disappointed - it was too heavy and difficult to use. Like Bruce Tate, maybe you've gone from "Bitter" to "Better, Faster, Lighter". With EJB 3 shipping in early 2006, maybe it's time to take another look. We'll compare EJB 3 with alternative
frameworks - Spring and Hibernate - to see if EJB 3 has closed the gap.

Spring and Hibernate seem to fill the void left by previous J2EE specifications - the need for simple development, deployment, and testing. The EJB spec committee listened to the Spring and Hibernate
communities, and the result is EJB 3. But does it deliver? With the widespread use of Spring and Hibernate, does EJB 3 matter anymore?


If you're curious about these issues, this talk is for you.
This presentation covers:

* Architecture Overview
* Architectural Issues (Transactions, Connection Pooling, Configuration)
* The Problems with EJB 2.1 (and earlier)
* Improvements in EJB 3
* EJB 3 limitations
* Spring - Everything You Always Wanted
* Session Beans versus Spring Beans
* Hibernate
* CMP Entity Beans versus Hibernate
* What Spring and Hibernate don't have
* Testability Issues - In-Container & Out-of-Container


We'll walk through each issue and debate the pros and cons. Just like an eye doctor appointment, we'll try to answer - "Which is better: technology 1 or 2?"


Intended audience: Experienced Java/J2EE/Spring/Hibernate developers and architects

Have you tried to deploy J2EE Web Services and thrown up your hands in frustration at the lack of tool support? Do you want to know how to develop and deploy Java EE-compliant Web Services so that they work every time? Would you like to see how to develop/deploy Web Services in Spring with XFire? Are you wondering if SOA is just hype and fluff? Do you think SOA is just marketing's re-packaging of Web Services? Would you like to know how Web Services and SOA (Service-Oriented Architecture) fit together? If so, then this talk is for you.

The new Java EE 5 Web Services standard and Spring/XFire were both designed for interoperability and simplicity. We'll show how to develop a POJO (Plain Old Java Object) as a Web Service using each technology stack. We'll also show how to design Web Services and how this fits with SOA.
This presentation covers:

* Web Services Overview
* Business Reasons for Using Web Services
* Java EE 5 and Web Services (including Java EE 5 annotations)
* Implementing/Deploying a Java EE 5 Web Service
* Implementing/Deploying a Spring/XFire Web Service
* Developing a Web Service Client
* Web Services Architecture and SOA


Intended audience: Experienced Java/EE architects & developers

A number of new features have been introduced in Java.
What benefit do these features offer you. Are there
issues with using these features. For instance, when should you use annotation? 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 5.

Portals and Portlets allow you to personalize your web application. However, developing and deploying portlets across different portals can be a challenge. What is WSRP and JSR-168. How are these related and how are these different? Are these competing technologies or do they
work with each other?

In this presentation we will introduce you to these standards and related technologies. We will take an example based approach. We will take closer look at tools and techniques for portlet development.

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 p
