This one's for all the "architects" out there designing and specing services, and those who have to work with them. Whether you are building it or consuming it, the most painful thing about sharing a service is sharing an understanding of what the service does. This presentation teaches you how to dispel ambiguities, techno-mumbo-jumbo, and reliance on institutional knowledge that bogs down service development and testing today using the 5 essential parts of an interface specification known as Operation-State Modeling (OSM).

WSDLs and XSDs describe the structure of service messages, but its not enough to describe the intended behavior of the service. Poorly-written English-language docs are the defacto standard of the day for describing service behavior. If you're like me, that seems completely ridiculous. Just like messages models (WSDL/XSD) are machine-consumable, so should behavior descriptions.

This presentation introduces the OSM way for specing services that avoids the painful and inevitable consequences of Word doc descriptions -- slow development and testing because of: subjective requirement interpretations by developers and testers, inconsistency, and ambiguity. A properly-written spec is objectively consistent, without unnecessary ambiguity, and ultimately stunningly faster to implement and test. This introduction will explain and demonstrate the 5 essential parts of a service interface specification.

Introduction to The Java API for RESTful Services (JAX-RS). RESTful Java web services are a pretty radical departure from what you are probably familiar with. JAX-RS avoids the "Java method == service operation" typical in all the popular web service stacks, opting instead for a much more comfortable way of making information services available over HTTP. For the busy developer who wants a fast, practical introduction to RESTful services and the JAX-RS API in particular.

This talk starts by differentiating the RESTful model that JAX-RS relies on from the more common RPC model of web services. Basically, RESTful services use (entity + verb) as the target of a service request, which turns out to be such a better way of doing things compared to the RPC service model where the verb is king.

The introduction is brief so we can get on to several practical JAX-RS examples. We'll look at implementing a RESTful service with a service class, identifying target entities and verb, different kinds of parameters, and how other RESTful concepts map to the JAX-RS Java 5 annotations. We'll make sure to have time as well to demonstrate consuming a public RESTful service in Java.

As developers, we sometimes get to make choices about the technologies we use, sometimes not. We base these decisions on personal experiences, recommendations from others and a general sense of where the industry is going.

Web Services have been all the rage for several years now. We have been told time and again that we should be building systems around them; as an industry, we've never been more confused. Perhaps it is time to Give it a REST.

Part of the problem with the conventional Web Services technology stack is that it is more complex than it needs to be for small to medium-sized systems. All of the examples show how simple it all is, but how often do we really need to check the temperature or get a stock quotation? Real systems that are built out of these technologies are rapidly spiraling toward incomprehensibility, unmaintainability and (shocker) insecurity!

SOAP has a place, but so does REST, a simpler architectural style for invoking services in a language- and platform- independent way. This talk will motivate REST, explain how it fits in to other Enterprise and Web technologies and help give you some ammo for suggesting that your organization give it a REST too.

We will look at getting started with the Restlet API, using conventional containers and advanced environments like NetKernel to build scalable REST-oriented systems.

This talk should be accessible to everyone but is probably intermediate level.

By Brian Sletten
If you have started to take a look at REST as way of exposing web services or managing information spaces, you may be frustrated by the support offered by legacy containers. There is no direct support for REST concepts in the J2EE specs (yet). XML-based configurations are so 1990's. Come learn about Restlets, a little API that has caught the attention of many in the RESTafarian community.

The Restlet API was created by a guy who wanted object-level support for RESTful concepts, but didn't want to make the move to an advanced resource-oriented environment like NetKernel. He wanted his REST and conventional environments too. He also wanted a path to more modern containers that aren't tied to a blocking I/O model like the Servlet spec is.

This talk will include a brief review of REST and its primary concepts and will then provide an introduction to the Restlet API and how it supports these ideas. It will then focus on standing up a REST-oriented infrastructure using the Restlet API and a variety of other open source tools to support a publish/find/bind infrastructure without touching SOAP/WSDL/ or UDDI.

This talk will not try to convince you about using REST. If you aren't familiar with the concepts or want convincing, please come to the "Give it A REST" talk first.

Prerequisite: Give it a REST (unless you are very comfortable with REST)

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 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.

You're a good Java programmer. You understand the JDK libraries and how to use them. The problem is that many fundamental APIs don't take the bigger performance picture in mind. Garbage collection can end up killing your app if you aren't careful. Concurrency problems and contention can keep your well-intentioned software from leveraging modern hardware architecture that support multi-core and multi-cpu systems.

Who knew that simply using the standard library code the way it was designed was opening you up for performance problems in your apps?

Don't worry, Javolution has your back.

Javolution is a small (300K) API designed to bring many of the benefits of the Real-Time Java Specification (RTJS) to J2SE, J2ME, GCJ and CLDC through deliberate design decisions.

It includes re-implementations of the java.util, java.lang, java.text, java.io and java.xml to demonstrate time-deterministic behavior. It also includes a framework for testing its own performance, supporting parallel computing, communicating with C/C++ applications and a real-time object to XML marshalling framework.

Come see how you can get some of the time-determinism and concurrency benefits in either your client or server side applications. This is a fairly deep talk and is largely a decomposition of an API that changes the runtime characteristics of the VM's runtime performance with only the tools offered by the language and the VM.

By Brian Sletten
How well do you understand the dynamics of your applications? In our systems, we detect when simple things happen. Customers log in, people buy things, a stock is sold at a particular price, inventory shifts locations... all of these events mean little things, but what about the larger picture? Complex events are particular patterns of simpler events that suggest something deeper is happening. Do you know how you'd discover these bigger picture occurrences? Come hear how the Esper open source software represents a new class of complex event processing (CEP) frameworks that can be added to even high volume, high transaction systems.

Trying to write software to track event occurrence is difficult to do correctly and almost impossible to do efficiently. The problem is that the higher volume and performance our systems get, the harder it becomes and the more important it is to highlight interesting or unexpected activity that isn't represented simply by a log entry.

Complex Event Processing (CEP) and Event Stream Processing (ESP) systems are emerging as a new strategy for processing and detecting complex sequences of more rudimentary events that could have bigger implications to your production systems. While commercial software is starting to add this behavior, Esper represents one of the most accessible and widely-used frameworks for adding CEP/ESP capabilities to Java applications.

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
Facelets is a combination of Tiles and Tapestry, and it's the hottest JSF-related open source project on the planet. It's popularity is well deserved, and in fact, much of what is in Facelets today will make its way into the JSF 2.0 spec due out in 2008. So not only can you come to this session and see some really cool demos that you can put to use in the real world, but you'll also be learning JSF 2.0 before it's even been defined! How's that for a ROI?

This session is 90 minutes of nothing-but-Facelets, so we're going to cover a good bit of ground. You'll see all of the basics, such as templating, error handling and debugging, and some of the more advanced aspects, such as creating your own components and tag libraries.

Prerequisite: Some knowledge of JSF is essential. If you're familiar with a templating framework, such as Velocity or Tiles, that's a plus, but not required.

By David Geary
This talk explores the RichFaces Ajax framework, which is really two frameworks: Ajax4jsf and RichFaces components. In this session you will see how to implement low-level Ajax functionality using Ajax4JSF, and how to use high-level Ajax components from RichFaces.


The JSF spec has changed little since JSF debuted in 2004. However, the open source community is a frentic cauldron of activity that has produced lots of cool innovations, many of them related to Ajax. In this talk, we'll look at two of the most popular open source Ajax frameworks for JSF: Ajax4jsf and RichFaces.

Ajax4jsf gives you a very capable set of low-level Ajax tags (JSP or Facelets), along with their corresponding APIs, that let you easily incorporate Ajax features, most of the time by just using a custom tag or two. Ajax4jsf is an ideal solution if you want to add Ajax functionality to an existing JSF application.

RichFaces components is a library of components built on top of Ajax4jsf. You get basics such as toolbars list shuttles, and a MS Virtual Earth component.

In early 2008, the JSF Expert Group has begun to focus it's attention on incorporating concepts from best-of-breed JSF Ajax frameworks, such as Ajax4jsf and ICEfaces. What you learn in this session will give you both a preview, and a leg up, on JSF 2.0.

Prerequisite: Some knowledge of JSF is required, in addition to familiarity with Ajax.

By David Geary
Have you ever stopped to think that you need to learn two frameworks to develop a non-trivial, database-backed, web application? Struts and iBatis; JSF and Hibernate; Tapestry and EJB3.0. Two frameworks. And then you have to learn to use them together. Why do we have to learn two frameworks just to retrieve "Hello World" from a database and show it in a view. Isn't that crazy?

Now you can use one framework, and use one component model. One. Isn't that nice?

Seam, a framework built on JSF and EJB3.0, unifies the JSF and EJB component models. Seam is a steam roller, quickly gathering market share among JSF newbies and longtime believers alike. Come see what it's all about.

This session is an introduction to Seam. If you're already using Seam, then you might want to see what else is on the schedule during this talk, because we're going to cover the basics, such as validation and data models. But if you know a little about JSF and you're curious about Seam, this talk is for you.

Prerequisite: Some knowledge of JSF is required. If you don't know what a managed bean is, for instance, then attend JSF Whirlwind before this session.

By David Geary
The Google Web Toolkit (GWT) is truly a revolutionary framework that lets you develop Ajaxified web applications without knowing anything about Ajax or JavaScript. But the GWT goes way beyond basic Ajax by letting you implement desktop-like applications that run in the ubiquitous browser.

In this, the first of a two-part session on the GWT, you will learn about the framework and its fundamental capabilities, such as: rapid development with project and application generators; the GWT widget hierarchy; remote procedure calls; the GWT's history mechanism, including its integration with the Back button and bookmarks; and integrating JavaScript frameworks, such as Script.aculo.us, with your GWT applications.

By David Geary
In the second part of this talk, you will learn how to extend the GWT by implementing custom widgets, including a scrolling viewport and a drag and drop framework. After discussing custom widgets, you will see how to integrate database access into your GWT applications, and how to deploy your GWT applications to external servers.

You will also learn how to integrate GWT widgets into legacy applications built with web application frameworks such as Struts, JavaServer Faces, or Tapestry. The GWT is one of the most powerful Ajax frameworks on the planet, and one of the few that let you easily implement desktop-like applications that run in a browser, and because of that, it has gained incredible mindshare in a short period of time. Come to these two sessions on the GWT and see what all the buzz is all about.

Groovy is an agile dynamic language for the Java platform. The language and its libraries bring many things to the table to ease the process of building applications for the Java platform. This session provides a detailed run through Groovy with lots of code samples to drive home the power of the language.

Dynamic languages provide a lot of power and flexibility compared to statically typed languages. Groovy brings that power and flexibility to the Java platform in a way that is totally compatible with all of your existing Java code, tools and infrastructure. This session covers all of the fundamentals of Groovy and gives developers a whole lot of practical information they need to get started with the language.

By Jeff Brown
Dynamic languages bring a lot of interesting elements to the table for teams interested in doing Test Driven Development (TDD). Groovy lends itself very well to TDD and this session demonstrates many features of the language and its libraries that help teams build more testable systems and build better tests.

The value of Test Driven Development (TDD) has become widely accepted. The practice has extended beyond just XP teams. Good TDD practices yield high quality software and help teams maintain confidence in their software as complexity grows. The dynamic nature of Groovy makes TDD easy and fun. Groovy may be used to unit test not only Groovy code but other code as well. Testing Java code with Groovy is a snap. Learn to use the power of Groovy to test your systems.

By Jeff Brown
Metaprogramming is a key component in building truly dynamic and flexible applications with Groovy. Groovy's metaprogramming capabilities bring great new possibilities to the table that would be very difficult or just plain impossible to write with Java alone. This session will demystify a lot of the magic that seems to be going on inside of a Groovy application.

When Java developers are first introduced to Groovy one of the first things they notice is how much easier things are in Groovy compared to Java. Boilerplate code typically generated by your IDE all melts away to nothing in a Groovy bean. Creating XML is a snap, not a tangled mess. File I/O is a breeze. Those developer productivity gains are an important part of the story. However, in addition to making easy the things you are used to doing the hard way Groovy brings whole new capabilities to the party that Java developers don't even think about because you can't do those things with Java. Many of those capabilities are made possible because of the powerful metaprogramming capabilities of the language. Learning the metaprogramming capabilities of the language takes developers the rest of the way to fully taking advantage of the power of Groovy. The metaprogramming capabilities offered by the language provide everything that an application development team needs to build systems that are far more capable than their all Java counterparts.

Prerequisite: A Thorough Introduction To Groovy

Grails is a full stack MVC framework for building web applications for the Java platform. Grails makes web application development both fun and easy. This session covers all of the fundamentals of building web applications with Grails.

Businesses need rich web applications and developers want to be able to build those applications without the pain that usually comes along with doing so. Grails addresses these needs very well. Grails demolishes many of the pain points that Java developers have almost (not quite) become numb to after years of suffering. This session covers all of the fundamentals:

- Introduction To Grails
- Domain Objects
- Controllers
- GSPs
- Custom TagLibs
- GORM

By Jeff Brown
Grails makes web application development both fun and easy. This session dives beyond the basics to cover advanced details of Grails that bring the really exciting features to your applications.

Getting started building web applications for the Java platform is easy. Following that through to rich interactive applications that solve the business needs is more tricky. Grails goes the whole way to address pain points not only for simple applications but of real enterprise applications with real demands. This session steps through many of the advanced features of Grails that help get your applications through that last 20% that teams often struggle with.

Prerequisite: Grails - Agile Web 2.0 The Easy Way

By Ken Sipe
Well the standards created EntityBeans.... yea. and the community created Hibernate. Fortunately the standards body learned some lessons and created JPA. JPA requires a vendor implementation and none make a better choice then Hibernate. Combined with Spring this trio is a powerhouse when it comes to developer productivity on applications requiring persistence.

This session will look at in detail the persistence capabilities of the latest Spring 2.5 and how to provide data access capabilities, including nicely added features for unit tests. We'll focus the persistence discussion on JPA and examine a number of ORM mapping scenarios and how JPA maps to them. We'll focus on the spring integration including transactional capabilities.

By Ken Sipe
Spring 2.5 is brand spanking new, with a number of fantastic features. With growth of large and complex Spring applications which struggle with xml manageability and with the added pressure of Guice and SEAM there is a push for less XML, with solution leaning towards annotations. Spring 2.5 adds to the toolset provided in Spring 2.0 to provide a development environment where XML is greatly reduced... or eliminated if you so choose.

The session walks through the new Spring 2.5 enhancements, then dives deep into annotation oriented injection. The demonstrations include standard applications as well as a look at the new Spring MVC.

By Ken Sipe
Scale... what is scale... how do you applications which are scalable. How do you know if the application scales?

This session will look at server topologies and state management and how it effects scale. We'll detail a number of metrics to know and observe. In addition tools of the trade will be demonstrated such as jmeter.

By Ken Sipe
A live Hacking demonstration exposing the tools and techniques used by Hackers.

A look at the growing space referred to as ethical hacking or penetration testing. We'll look at example attacks which include:
Client-side exploits
Sql-Injections
Brute force attacks
Man-in-the-middle attacks
Key logging

By Ken Sipe
The success of an Agile / SCRUM project is a successful start. The first interaction is often referred to as iteration 0. Other iterations have a set of stories with clear acceptance certain which establishes the velocity of the team and its effort. What then is accomplished in iteration 0? How do we get an Agile process started.

This session will outline all the "pre" activity tasks which led into an agile development process. As well as the establishment of a tasklist of iteration 0, include the establishment of development environment, configuration management details. This will include several case histories examples of Iteration 0.

By Ken Sipe
Thoughts lead to words, words lead to action, actions lead to habits. In this session we'll sharpen the development saw in the process of understanding what makes a hyper-productive programmer. The focus will consist of developer habits and development processes.


As described in the book "7 Habits for Highly Effective People", there are habits which are characteristic of highly effective people. Clearly there are hyper-productive developers which distinguish themselves from the development pack? what is it that makes the difference? What are the habits and practices of highly effective developers?

This session will focus on individual developer habits, as well as team practices and the processes which result in high quality running software.

By Neal Ford
Most developers think that "TDD" stands for Test-driven Development. But it really should stand for "Test-driven Design". Rigorously using TDD makes your code much better in multiple ways.

This session demonstrates how stringent TDD improves the structure of your code. I discuss TDD as a technique for vetting consumer calls, using mock objects to understand complex interactions between collaborators, and some discussions of improved code metrics yielded by TDD. This session shows that TDD is much more than testing: it fundamentally makes your code better at multiple levels.

By Neal Ford
This session demonstrates that "Agility" and "SOA" complement each other quite well. Just because SOA is buzz-word compliant doesn't mean that you should throw good practices out the window. This session demonstrates how you can apply the principles of agility to building highly complex distributed enterprises.

Managers and ivory tower architects seem to think that all the rules that apply to "normal" software don't apply to SOA. Ironically, they matter even more. Agility and SOA are closely aligned because SOA is about building complex distributed systems and Agility is about effectively building complex software. This session unveils the pillars of successful SOA and how to achieve them in a testable, iterative fashion. It discussing testing strategies, how to make your architecture more robust and maintainable, and how to design an evolutionary architecture.

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

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

Session Outline:

1. TDD
2. Static Analysis
3. Good Citizenship
• getters and setters
• Constructors
• Static State
4. YAGNI
5. Occam and His Razor
6. Question Authority

It turns out that ancient philosophers knew a lot about software -- did you know that Plato defined object-oriented programming? This keynote applies old lessons to new problems and old problems to new lessons. It describes why SOA is so hard, and why people in your company make bone-headed decisions. What other keynote includes Rube Goldberg, Aristotle, Dave Thomas, and Chindia?

Plato, Aristotle, Occam, Rube Goldberg, Dave Thomas, and Demeter...with pictures!

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.

This session shows how to fully exploit regular expressions. It begins with the basic premise of how regular expressions work, then shows how to take advantage of the RegEx library built into the Java platform. This session shows how to use wildcards, escape characters, meta-tags, character class operators, look-aheads/look-behinds, and how to use the greedy operators effectively. It covers regular expressions from the beginning through to advanced usage, both in Java and in tools that support regular expressions. This session is packed with real examples of regular expressions (including a game show with no fabulous prizes).

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


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

Session Topics:

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

The Gang of Four book should have been entitled "Palliatives for Statically Typed Languages", because the recipes it provides are cumbersome solutions to the problems it poses. Using powerful languages makes the solutions in the GoF book look hopelessly complicated. This session shows how to solve the same problems concisely, elegantly, and with far fewer lines of code using the facilities of dynamic languages.

The Gang of Four book was actually 2 books: a nomenclature describing common software problems and a recipe book for solutions. The vocabulary they defined is still useful. The recipes are a disaster! Dynamic languages (like Groovy and Ruby) have powerful meta-programming facilities far beyond statically typed languages. It turns out that many of the structural design patterns in the Gang of Four book and beyond are much easier to solve with meta-programming. This session compares and contrasts the "traditional" approach of design patterns with a more nuanced meta-programming approach. Using language features creates cleaner abstractions with fewer lines of code and little or no additional structure. This session shows one of the many reasons that dynamic languages are such a hot topic.

Developers from the 1980s would be shocked at how inefficiently developers use their computers because of the advent of graphical operating systems. This talk describes how to reclaim productivity afforded by intelligent use of command lines and other ways of accelerating your interaction with the computer and bending computers to do your bidding. Stop working so hard for your computer!

In The Productive Programmer, I identify 4 principles of productivity: this talk goes into great detail on 2 of those principles. It defines the principles and describes their use, but the primary focus of this talk is on real-world examples of how you can use these principles to make yourself a more productive programmer. Acceleration covers ways to speed up development by taking command of your computer. This includes keyboard shortcuts (including ways to learn them and make better use of them) in both IntelliJ and Eclipse. Automation refers to making the computer do more work for you. This talk includes tons of examples, all culled from real-world projects. Note: This is a companion talk to my other talk, Productive Programmer: Canonicality and Focus, but each talk is completely independent of the other -- they are not "Part 1" and "Part 2".

Getting work done in modern office environments is a daunting task. This session tackles 2 of the things that drag down developer productivity: lack of focus and creeping repetition.



In The Productive Programmer, I identify 4 principles of productivity: this talk goes into great detail on 2 of those principles. This session defines the principles of Canonicality and Focus, and describes their use. But the primary focus of this talk is on real-world examples of how you can use these principles to make yourself a more productive programmer. Canonicality (the DRY principle from The Pragmatic Programmer) discourages repeating artifacts in projects. This talk shows effective ways to avoid this repetition. I show examples of creating DRY documentation, O/R mapping, database schemas, and development environments. Focus describes how you can utilize your environment (both physical and computer) to greatly enhance your productivity. This talk includes tons of examples, all culled from real-world projects. Note: This is a companion talk to my other talk, Productive Programmer: Acceleration and Automation, but each talk is completely independent of the other -- they are not "Part 1" and "Part 2".

This session describes JRuby, the 100% pure-Java implementation of the Ruby programming language. It covers the basics of programming with JRuby and examples of how to integrate it into existing Java projects.


Like hamburger & fries and turkey & dressing, JRuby allows you to harness the awesome power of Ruby in your Java projects. This session describes the origins, capabilities, and limitations of JRuby, the 100% pure-Java implementation of the Ruby programming language. This session also demonstrates some areas where it makes sense to mixin Ruby and Java code: Rails on Java, testing, and dynamic programming. JRuby is a powerful implementation of Polyglot Programming, and this session shows you how to leverage this cutting-edge concept.

Session Topics:

• JRuby's origins
• Calling Java from Ruby
• Calling Ruby from Java
• Limitations and pitfalls
• Example usage
• Rails on Java
• Testing
• Dynamic programming
• The future

Ruby is the revenge of the Smalltalkers. Not since Smalltalk has a language had such powerful meta-programming facilities. While this may seem like a minor feature, it turns out that surgical meta-programming allows solutions to problems that are clearer, more concise, more maintainable, and take orders of magnitudes fewer lines of code.

This session shows one of the reasons that JRuby is the most
powerful mainstream language today: meta-programming. It shows tons of
meta-programming techniques in Ruby, including open classes, the shadow
meta-class, defining methods, method_ & const_missing, dynamically
adding and removing mixins, and more. And each of these comes with an
example that actually makes sense!

Session Topics

• Modules
• Structs
• Freezing
• Messages and Dynamic Invocation
• The Shadow Meta-class
• Code as Objects
• Delegation
• Open Classes
• Aspects
• Missing!
• Const
• Method
• Reflection
• Mixology

Java's threading capabilities took a serious turn for the better with the release of Java5, thanks to the incorporation of the java.util.concurrent packages, a set of pre-built components for thread pooling and execution, synchronization, and more.

In this presentation, we'll explore the Thread API, the Java threading model beneath it, and the enhancements made in Java5 to make it easier for Java code to walk and chew gum at the same time.
