Session Descriptions

Scott Davis - Author of "Groovy Recipes"

Easing into Agile

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.

Guerrilla Web Techniques

Frameworks? We don't need no stinkin' web frameworks. OK, so maybe that's overstating the case. Web frameworks do plenty of good things, but sometimes they can also be golden handcuffs. Too many web developers fall into the trap of thinking, "If it can't be done by my web framework, then it simply can't be done."

Holistic Testing

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...

Real World Web Services

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.



Scott Delap - Author of Desktop Java Live

Ajax, Flash, and Java - Choosing The Right Rich Client Technology for Your Next Project

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.

Creating Polished Swing Applications

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.

Introducing the Eclipse Rich Client Platform

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.



Neal Ford - Application Architect at ThoughtWorks, Inc.

Advanced Enterprise Debugging Techniques

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

Language-oriented Programming and Language Workbenches: Building Domain Languages atop Java

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.

Real-world Agile Development

Lots of developers want to use Agile development technique but don't know where to start. This session discusses how to get started with Agility, the key benefits you can expect, and the pitfalls to avoid.

Regular Expressions in Java

Regular expressions should be an integral part of every developer?s toolbox, but most don?t realize what an important topic it is. Regular expressions have existed for decades, but many developers don't understand how to take full advantage of this powerful mechanism, either through command line tools and editors or in their development.

SOA: Next Wave of Enterprise Development or Return of the Son of CORBA?

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.

Testing with Selenium

This session describes the use and workings of Selenium, the open source web user interface testing tool.



Justin Gehtland - Founder of Relevance, co-author of Better, Faster, Lighter Java

Advanced Hibernate

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.

Ajax Architecture

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.

Java Platform Security and JAAS

The Java platform is built from the ground up with security in mind. This talk will introduce the security features of the J2SE, building quickly from the basic classes to realistic examples. You will learn the core APIs: SecurityManager, AccessController, Permissions and Policy JAAS Subjects, Principals, and LoginModules

JavaScript for Ajax Programmers

This presentation covers JavaScript from the perspective of an Ajax 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 the Ajax toolkits themselves.

Spring Dependency Injection

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.

Spring Intro

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.

Spring Security with ACEGI

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.



Andrew Glover - Founder of easyb

Groovy 101: core Groovy

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.

Taking Quality to the Next Level through Code Coverage Analytics

Understanding what code coverage represents, how to effectively apply it, and how to avoid its pitfalls will give you an unprecedented understanding of how unit tests may or may not be covering you from sneaky defects.

Unit Testing Best Practices

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.

Unit Testing Java Objects with Groovy

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.



Jason Harwig - Senior Software Engineer at Near Infinity

Unobtrusive JavaScript

With the recent popularity of AJAX, JavaScript has entered a renaissance in the last year, bringing with it both cool new features and the potential for a mess. An increased number of scripts executing in web pages can lead to embedded behaviors fighting with each other and crowding "onEvent" attributes. Most developers know that embedding script in html is not a best practice, but creating reusable and gracefully degrading libraries in JavaScript is not a widely known skill.



David Hussman - Agility Coach/Instructor/Practioner

Automating Business Value with FIT and FitNesse

The presentation will briefly discuss stories, the origin and authoring of story tests, and a demonstration of how FIT and FitNesse (FIT living within a Wiki) can be used to automate acceptance tests.

Creating, Telling, and Tracking User Stories

The participants of this session will become agile customers and product owners, using personas to create stories for a sample product development.

Losing Battles and Winning Wars: Adopting Agile

Adopting agile is different for each company, but most companies will go through some amount of change during the adoption of agile.

Ready, Set, Agile?

As with many methodologies, moving agile into an organizations poses larger challenges. Before jumping in, it helps to ask a few questions before "racing toward agility". This session will provide 3 tactical steps that can help your adoption of agile.

“Show Me the Numbers” - Agile Planning Tools and Techniques

This session will focus on tools and techniques for tracking an agile project plan from creation to project completion.



Ramnivas Laddad - Author of AspectJ in Action, Principal at SpringSource

Enterprise AOP with AspectJ

Enterprise application development is a gold mine for applications of AOP. There are many crosscutting concerns found in a typical enterprise application, ranging from well-known security and transaction management to application- and technology-specific concerns. Using AOP leads to implementations that are easy to understand and easy to change.

Performance Monitoring in J2EE Applications

J2EE has become the main new platform for enterprise application deployment. Good performance is an important business requirement. Supporting this requirement needs application profiling during the development phases and performance monitoring after application deployment. Come to this session to understand challenges and choices in monitoring J2EE applications.

Spring AOP in Depth

Support for aspect-oriented programming is an important part of the Spring framework. It is the AOP support that allows keeping implementation of functionality such as transaction management and security out of your POJOs. While many developers only use aspects provided with Spring, once you understand how it all works, you can make a better use of those aspects, extend them, and write brand new aspects.

The State of AOP

A lot is happening in the field of Aspect-oriented programming (AOP). AspectJ and AspectWerkz, the two leading AOP implementations, have merged, bringing in their respective strengths. The merged version, AspectJ 5, adds many new features aimed at simplifying writing and deploying aspects. The new features include an annotation-based and XML-based syntax to define aspects, support for new Java 5 concepts, and load-time weaving. The tools support for AOP continues to improve, as well. Further, the most popular IOC framework, Spring, enables integrating aspects written in AspectJ. There is also serious discussion and preliminary work going on to support AOP right into the VM itself. All in all, there is a lot to learn about the changes in the exciting field of AOP. This session is designed to help you get up to date with all these changes.



Matthew Porter - Co-Founder of Contegix

WebWork 2.2 / Struts 2.0

In November 2005, WebWork and Struts developers announced a merger between the two framework to build Struts Action Framework 2.0. The resulting product will be built upon the foundation of WebWork 2.2 with a slew of new features, including a migration layer for Struts Classic. This session introduces the audience to this revolutionary framework and teaches some new concepts to those already using WebWork.

WebWork/Struts 2.0 & Spring

From it's early pre-release, WebWork 2 (the core of Struts 2.0) has included Inversion of Control. This implementation, based upon interfaces, served the WebWork community well due to its simplicity; however, it lacked a number of features. Beginning in version 2.2 and continuing with Struts 2.0, the internal IoC container has been deprecated and replaced with the more powerful Spring IoC.



Mark Richards - SOA and Integration Architect, Author of Java Message Service

EJB 3.0 and New Java Persistence API

The new EJB 3.0 spec (JSR-220) offers some great improvements over the prior EJB specs in terms of development simplicity and new features. In this session we will take a look at the new EJB 3.0 spec and the new Java Persistence API. Included in this session will be a discussion about Java metadata annotations, simplification of enterprise beans (session and message-driven beans), interceptors, changes in transaction processing, and how the new Java Persistence API works. During the session I will be demonstrating how the EJB 3.0 spec differs from the EJB 2.1 spec through code example comparisons. I will also be discussing how the new Java Persistence API compares to related Java persistence options and whether we should be excited about the new persistence API or (yawn) sticking with what we have.

Java EE Command Pattern Architecture

Tired of dealing with EJBs but cannot use other frameworks like Spring? How would you like to replace all of your remote Stateless Session Beans with POJOs and still access them remotely within Java EE? By using the Java EE Command Pattern we can write EJBs as POJOs and solve many of the issues facing EJB, including testability, configuration complexity, and performance, and still remain within the boundaries of the Java EE container. The Java EE Command Pattern is a simple pattern that can significantly reduce the complexity of large-scale Java EE enterprise applications. In this session we will explore the numerous issues facing a typical EJB architecture and learn how the use of the Java EE Command Pattern can solve these issues. We will walk through the different design alternatives and see how the command pattern is implemented in both EJB3 and in Spring. Through interactive coding examples you will learn what components make up the Command Pattern framework and what simple coding changes are required to convert a complex remote EJB-based application to a much simpler remote POJO-based application.

The Enterprise Service Bus: Do We Really Need It?

There has been a significant amount of buzz in the community and industry about the definition and role of an Enterprise Service Bus (ESB), particularly within the area of Service-Oriented Architecture (SOA). In this product-agnostic high energy session we will take a step back and consider whether we really need an ESB. Through real-world application and architecture scenarios we will see where an ESB would be helpful and where it would be overkill. We will take a look under the hood and find out just what an ESB is really doing, and take a quick look at JBI (JSR-208) and see the impact it has on the ESB worls. Then, using product-agnostic coding examples we will learn what an Enterprise Service Bus is supposed to do, then answer the question about whether the ESB is just a bunch of hype or if we really need it.



Jared Richardson - Agile coach and co-author of Ship It

It’s All About the Platform

Validating a platform is hard work. We'll look at several approaches and strategies you can use to keep your platoform solid.

Pragmatic Tracer Bullets

Are your product designs hit or miss? Do you have trouble building a loosely coupled system? Is your code incestuous? Refactoring not an option with your code base? Tracer Bullets help keep your project out of the fire.

Tracer Bullet Development:

* helps you create great software
* lends itself to an iterative cycle
* can be used for demos early and often
* is easily refactored
* allows your teams to work in parallel
* makes a very testable system

Software Development Techniques

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.

Software Tools That Make Life Easier: Part One

a.. Do you spend more time fighting your tools than writing code? b.. Do you avoid merging your code with your teammates because of “Integration Hell”? c.. Do the same bugs keep sneaking back into your product? d.. Do your builds depend on the roll of the dice?

A good set of infrastructure tools can go a long way toward smoothing out these and other problems. Come see how to make your toolset work seamlessly in the background so you can Just Work. We'll cover source code management (SCM), build scripts, automated test harnesses, automatic builds, feature tracking and issue tracking.

Software Tools That Make Life Easier: Part Two

This talk is a continuation of Part One of the Tools talk. During Part Two we'll cover Continuous Integration, automated testing, bug tracking, and feature tracking.



Brian Sletten - Forward Leaning Software Engineer

Experiencing the Semantic Web

If you attended the "Introducing the Semantic Web" talk or have been paying attention, you understand where much of the current Web falls down. By building on languages like RDF and OWL our software will be able to do more for us to improve search and knowledge discovery. This talk is a more hands on introduction to using the core technologies of the Semantic Web for managing, storing querying and inferencing over metadata.

Introducing the Semantic Web

Just as the world is feeling comfortable with the Web, Tim Berners-Lee et al inform us that what we have seen so far is just the beginning. His original plans at CERN were larger and grander. The Semantic Web is the new vision of machine-processable documents and metadata to improve search, knowledge discovery and data integration and management. While there are many naysayers chiding such grand visions, there are also pragmatic and useful technologies emerging that can be applied today.

Introduction to NetKernel : Software for the 21st Century

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.



Venkat Subramaniam - Founder of Agile Developer, Inc.

Java 5 Features, What's in it for you?

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.

Open Source Tools for Agile Development

As a Java developer, you have taken the time to learn the basics of the language and relevant parts of its rich API. However, you need more than that to develop serious industrial strength applications. In this presentation, the speaker will introduce you to a number of open source tools which you can use to improve your application quality and your development process.

Portal Standards and implementation

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?

Practices of an Agile Developer

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.

Refactoring your code - a key step in agility

Refactoring is one of the core practices in Agile Software Development. Refactoring is based on some core principles that apply to more than writing good code. But, what's refactoring? Why should you do it? How do you go about doing that? What tools are available to successfully refactor your App?

Working with Rules Engines

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.

Cascading Style Sheets: a Programmer's Perspective

Today, the Cascading Style Sheets (CSS) specification is well supported by the major browsers (Mozilla, Safari, IE). CSS has become a practical tool for web content publishers that has helped turn heavy, buggy, and hard-to-maintain web sites into lean, clean, and stylish ones. CSS is sometimes stereotyped as a technology geared for graphic designers and artists. I beg to differ: I see CSS as a refactoring tool for content publishers and one that encourages content to become more strongly semantic. Come see a developer's perspective on CSS and how it can be applied to refactor your web content.

Hibernate by Example

This talk covers the core of the Hibernate Object/Relational Mapping framework by example; that is: in a hands-on manner.

Naked Objects Applied

Join Eitan in this hands-on session on Naked Objects. This session uses the "learning by doing" approach to learning an API or framework. Naked Objects is a powerful tool that can give you a significant advantage in the development of business systems. It gives you the ability to prototype a software application so quickly that it can be performed during information gathering phases of a project. It gives you the power to codevelop the core business model of your application with a non-developer business expert at your side. No prerequisite knowledge of Naked Objects is required.

XML Data Binding with JiBX

JiBX is an open source XML data binding API for Java. JiBX is younger than most other APIs in this space (Castor XML, BEA XMLBeans, JAXB). JiBX's philosophy on data binding is that: [a] databinding should be fast, and [b] databinding frameworks should allow for the divergence and evolution of your codebase from its xml representation. JiBX excels on both counts and consequently is a practical tool for the purpose of data binding. In this session, Eitan will be covering all aspects of Dennis Sosnoski's JiBX framework.



Dave Thomas - Pragmatic Programmer, Ruby, Rails, Process Improvement

Herding Racehorses and Racing Sheep

Are you frustrated by experts who can't tell you what to do, or by junior team members who refuse to see the big picture? How can you best develop careers: both yours and those of your teammates and managers? How can we learn to apply experience more effectively, and why do the many approaches designed to tame complexity actually end up increasing it?

Ruby on Rails

The Ruby on Rails framework has exploded onto the scene over the last few months. Propelled by some genuine benefits, and fueled by a whole lot of controversy, Rails seems here to stay. So, is it a Java killer? (No.) Is it a great way to develop certain classes of web application? (Yes.) Does it really deliver the 10-fold increase in developer productivity that some have claimed? (It depends...)

Testing your Rails Application

The Ruby on Rails framework has unit and functional testing baked right in. In this talk we'll see how easy it is to get started with testing in Rails, and we'll explore jut how deep the testing support goes.

Using Ajax with Ruby on Rails

Ajax is becoming a requirement for new applications: it creates richer user experiences and more dynamic applications. However, doing Ajax by hand is difficult and error prone. The good news is that if you use Rails, you don't have to do Ajax the hard way.



Glenn Vanderburg - Chief Scientist, Relevance Inc.

Java Performance Myths

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.

JavaScript Exposed: There's a Real Programming Language in There! (Part 1)

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 Exposed: There's a Real Programming Language in There! (Part 2)

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.

Modern Project Infrastructures

The support infrastructure for your software project is a crucial factor for success. A new generation of tools offers significant benefits over their predecessors. This talk discusses how to choose the right mix of tools for a top-shelf project infrastructure.

Under the Hood of Java Memory Management

Most of the time, Java's automatic memory management works really well—it's one of the things that makes programming in Java a pleasant and productive experience, and it's nice that we don't have to worry about managing memory manually. However, although it's usually nice to ignore memory management, occasionally we have to pay close attention. Sometimes we need to take control of certain aspects of memory management. Sometimes Java programs do exhibit memory leaks, or unacceptably long garbage collection pauses, or very poor overall performance. But because Java's memory management is supposed to be "fully automatic," it can be difficult to find out what's really going on inside the VM.
