Prerequisite: Grails - Agile Web 2.0 The Easy Way

Agile Test Driven Development With Groovy

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.

Grails - Agile Web 2.0 The Easy Way

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.

Powerful Metaprogramming Techniques With Groovy

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.

Prerequisite: A Thorough Introduction To Groovy

Configuring Spring with Annotations

In this session, we will take a deep-dive into annotation-based dependency injection with Spring 2.5. You will learn how to combine annotation and XML formats, how to customize component scanning, and how to leverage Java 6 annotations within a Spring application. Since there is no "one size fits all" solution to application configuration, we will wrap up the discussion with general guidelines to consider when employing this approach.

Enterprise Integration Patterns with Spring - Part I

In the first-part of this two-part workshop, Mark will focus on the essentials of Enterprise Integration with Spring. First, he will take a whirlwind tour of Spring's enterprise integration support libraries. Next, he will discuss the "big picture" of an event-driven architecture based on messaging with an overview of key enterprise integration patterns. Attendees will leave with a clear understanding of Spring's integration capabilities and an appreciation for the benefits of message-driven architecture, ready to put that into practice in Part II.

Enterprise Integration Patterns with Spring - Part II

Building on Part I, Part II of this workshop will demo a series of messaging systems built on Spring. The samples will exercise event-driven scenarios involving distributed architectures with messaging and remoting. Each sample will highlight a variety of important enterprise integration patterns.

Simplifying Enterprise Applications with Spring, Part 1

Developing enterprise applications isn't easy. You not only have to worry about constantly evolving business logic, but also need to address infrastructure concerns ranging from transaction management and security to manageability and integration with diverse external applications. Spring, the most popular lightweight enterprise application framework, comes to the rescue by simplifying the common needs of enterprise applications. This session (part 1 of 2) presents the core concepts of the Spring Framework.

Simplifying Enterprise Applications with Spring, Part 2

This session (part 2 of 2) will cover advanced concepts in the Spring framework. While the core concepts in the first session will get you started with Spring, the advanced concepts in this session will help you be more effective at developing Spring-based applications.

Agile Project Management (With Just a Bit About Mingle)

You can read books about Agile projects, but you must consult real-world experience to really understand the dynamics of agile project management. This session discusses agile management topics including estimation, project tracking, and useful metrics (and how to obtain them). And just a little about Mingle, the agile project tracking tool from ThoughtWorks.

Code Metrics & Analysis for Agile Projects

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.

Evolutionary SOA

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.

Introduction to JRuby

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.

Keynote: Ancient Philosophers & Blowhard Jamborees

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?

Meta-programming JRuby for Fun & Profit

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.

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.

Test Driven Design

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.

BDD made easy

Behavior-driven development, or BDD, has attracted a lot of attention via RSpec in the Ruby community, but BDD's roots stem from JBehave, a Java based framework modeled off of the xUnit paradigm. But JBehave isn't the only framework available for Java developers-- with the advent of Groovy, new options are available for embracing BDD in the spirit of RSpec's innovative behavior based DSL.

Groovin' builds Gant get any easier

There's no question that Ant is the de facto standard for building Java applications; however, even its creator has acknowledged an inherent limitation with Ant's expressiveness due to its reliance on XML. Recently, the popularity of Ruby and the Rails framework has brought to focus Ruby's de facto build platform: Rake. Rake's expressiveness comes from its reliance on Ruby itself to define a DSL for software assembly. While Rake's ultimate focus is Ruby, there are a number of interesting projects that utilize expressive DSLs for building Java including Gant, which uses Groovy as a DSL format and builds upon Ant's existing cornucopia of tasks.

Tactical Continuous Integration with Hudson

This session will walk attendees through a series of iterations on a fictional Java project where an automated build system is created that facilitates compilation, testing, inspection, and deployment. This build system is then plugged into the Hudson CI server and as features are coded using Agile techniques like developer testing, attendees will ultimately see firsthand how a Continuous Integration process reduces risk and improves software quality.

How to Catch Hackers: Security Auditing and Logging

This session examines the code that developers must write in order to enable the detection of malicious activity and preservation of evidence after a security breach.

How to Do a Security Code Review

This session is a hand-on exercise in Java code review that will cover both manual and automated techniques. If you envision code review as a line-by-line slog through thousands of programs, you will be surprised to learn some effective techniques that reduce the tedium and increase your enjoyment of this activity (well, maybe not the enjoyment part). Familiar methods such as pair programming and peer reviews are a great place to start and will immediately increase the security of your code base.

Web Application Hacking

See the hacker's toolbox in action as various web applications are ripped open by exploiting simple software bugs. Common problems such as Cross-Site Scripting (XSS) and SQL Injection will be demonstrated and explained, along with more subtle vulnerabilities including privilege escalation, data tampering, and Cross-Site Request Forgery.

What You Don't Know About Cryptography

This session provides a gentle introduction to cryptography then covers the many subtle mistakes that even experienced developers make when writing cryptographic code.

Google Your Domain Objects With Hibernate Search

Hibernate is one of the pre-eminent object/relational mapping technologies, but the Hibernate Search project adds full-text search capabilities to an already extremely capable tool to allow you to Google your domain objects.

Prerequisite: A basic understanding of Hibernate.

Introduction to Hibernate

This session introduces the Hibernate Object/Relational Mapping (ORM) framework, showing the basics of persisting Java objects to relational databases. No prior knowledge of Hibernate or ORM is assumed.

Real World Hibernate Tips

Hibernate is a very powerful object/relational mapping framework. With the vast amount of power also comes the responsibility to choose which features of Hibernate to use and how to use them, as well as things to avoid. We'll look at some real world Hibernate tips and tricks in this session.

Guerilla Unit Testing Part 1: TestNG

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

Guerilla Unit Testing Part 2: The Weird and Wonderful EasyMock

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

Introduction to Tapestry 5

Tapestry 5 is a complete rewrite of Tapestry from the ground up. It takes everything good about Tapestry and cranks the volume up to eleven, while removing the frustrating parts of using Tapestry. This session takes the wraps off this new and innovative technology, showing off important new features such as live class reloading (the ability to change your Java classes and continue using the application without interruption or redeployment), the simplified coding model, and the total lack of XML. This session is of interest to those already using Tapestry 4, and those new to Tapestry and ready to jump on the bandwagon.

Pragmatic Patterns with Tapestry 5 IoC

Everyone likes the Gang of Four design patterns, but it's not always clear just how to make use of them in your day to day coding efforts. Hidden inside Tapestry 5 is an Inversion of Control (IoC) container that is structured around several common patterns (Chain of Command, Strategy, Decorator and Filter Chain will be covered). This isn't academic navel-gazing ... this is about leveraging the common patterns so that you can write code you can easily test, and about creating frameworks and toolkits that can be easily extended.

We'll see how Tapestry uses these patterns, and go from there into how you can apply the same techniques to your own projects, resulting in better, cleaner, more testable code.

10 Things Every Software Architect Should Know

An effective software architect understands that every application is different and requires unique choices regarding programming language, middleware, integration, data access, user interface design, etc. Richard Monson-Haefel has distilled knowledge from his own experience and from personal interviews with the World's best software architects to define 10 principles every software architect should know in order to be effective.

Developing Rich Internet Applications

With literally hundreds of RIA products (e.g., Adobe Flash, Nexaweb, Backbase) and open source Ajax projects (e.g. Dojo, GWT, Prototype) to choose from. Picking the right RIA technology for the job requires months of research. Richard Monson-Haefel has been researching and writing about RIA alternatives for two years and has already done the research so you don't have to.

Understanding Open Source Licensing

What does GPL, LGPL, MIT, Apache licenses, copy left, and dual licensing mean? Richard Monson-Haefel explains both the legal and technical implications of the major open source licenses in plain English. He explains when and how you can use open source in the enterprise and in the development of software products and how to protect your organization from abusing open source licensing.

Failures Come In Flavors (part 1)

The typical JEE application does not reach the fabled "five nines" of availability. Far from it. It's more like "double eights". Come see why enterprise applications and web sites are only serving users 88% of the time instead of 99.999%.

Part 1 of 2

Failures Come In Flavors (part 2)

What can we do about the dismal uptime of typical applications? We are asked to provide "five nines", but only reach 88%, on average. Come learn how to prevent the Stability Antipatterns from biting you. Apply these Stability Patterns to contain damage, recover from shocks, and survive disasters.

Part 2 of 2

The 90-Minute Startup

Cloud computing is taking the world by storm. Amazon's Web Services, EC2, and S3 provide completely virtual infrastructure, letting startup and existing companies create sites and web applications faster than ever before.

In this session, Michael will use cloud computing to create and deploy a fully-functional web site. You will learn how to create and run your own virtual infrastructure in the clouds.

Basic JPA & JPAQL

Doing basic Object-to-Relational Mapping is fun and easy with JPA. Annotate your persistent classes, define a couple of configuration parameters, and you're off and running. This session starts with a basic object model and adds persistence using annotations. Learn how to do mappings for your object model for simple and complex relationships. Also learn how to map Java5 constructs like Enumerations.

Unit testing with JPA can be tricky. Where do you use mock objects? How can I structure my unit tests to exercise my DAO's effectively? How do I unit test JPAQL? Do I need to enhance or can I use a LoadTimeWeaver in my unit tests? This presentation will show, using live code examples, how to effectively unit test JPA components so developers can have confidence in the code they build using JPA.

Enterprise JPA 2.0 & Spring 3.0 - Tips and Tricks for JEE5 Persistence

As with many technologies, the basics are easy. The hard part comes when the developer needs to do sophisticated integration, development, and testing as part of an enterprise application. A large enterprise application requires the developer to think of issues that affect the development, scalability and robustness of the application. This presentation will cover the advanced topics described below.

A large enterprise application often will have several sub-projects that each contain their own JPA persistence unit. This opens up a number of questions around how to organize the persistence units and how the code between sub-projects should interoperate. Developers will gain insight into these issues and will see a couple of solutions using live code examples.

10 Tips for Getting Your Project Back on Track

Software projects fail over and over for many of the same reasons. We'll look at some of the more avoidable problems and some solid ways to fix them, or avoid them in the first place.

Agile Software Testing Strategies

Creating and maintaining a solid automated test suite is critical to an Agile strategy, but often we're just told to "Do it." In this talk we'll look at several pragmatic strategies for creating and building your suite.

Build Teams, Not Products

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

Credit Card Software Development: Recognizing and Repaying Technical Debt

Technical debt has long been recognized in technical circles for years, but convincing your manager to budget time to repay "technical debt" has always been problematic. Let's couch the term technical debt concept in language more familiar to our managers: credit card debt.

Techniques 2009

There are a number of great techniques you can use across technologies and projects. Come hear some of my favorite ways to move "beyond" and contribute a few of your own. We'll discuss topics ranging from glue languages to ditching your IDE to building your brain.

Designing for Ajax, part 1

So you've convinced the boss that your new web application just has to have Ajax...but now what? With dozens of libraries making even the most blinkish of interactions trivial, how do you decided where to sprinkle the magic Ajax dust? This talk will give a plain old boring "web 1.0" an Ajax facelift with a focus on improving the user experience providing you with a game plan for introducing Ajax to your world.

Designing for Ajax, part 2

We'll pick up where Part 1 left off working in even more advanced approaches such as offline support with Google Gears.

Dojo: Getting Started

So you want to do some Ajax and you've rightly concluded that you don't want to build your own library. After some thought, you've settled on using Dojo - but you're not sure how to get going. This talk will introduce Dojo and discuss several ways that Ajax can improve your new or existing application.

JavaScript: the Good, the Bad, and the Ugly

Thanks to Ajax, JavaScript is cool again and developers are taking a second look at this much maligned language.

7 Habits of Highly Effective Developers

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.

Architecture and Scaling

Scale... what is scale... how do you applications that are scalable. How do you know if the application scales?

Hacking - The Dark Arts

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

Iteration 0

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?

JMX and Spring: Manageability for Spring-based Applications

This session describes management of Java resources using the Java Management Extensions JMX API. JMX provides a unified framework to instrument Java systems with monitoring and management capabilities.

Java Memory, Performance and the Garbage Collector

You are using Java, whew!!! No need to worry about memory, the garbage collector will handle that. Those who have had a memory issue in Java are not so naive any more. Often memory utilization and heap sizes are an after thought and are not recognized until the application is in production, often caused by application uptime, production request volume or production sets of data. When the OutOfMemory Error occurs, often the science of development seems to brake down and knobs are turned. First the (-mx) maximum heap space gets adjusted... More is better right. The next OutOfMemory, heads start scratching, code reviews start in earnest, and Google gets several new hits. Did you know that it is possible to get an OutOfMemory error without running out of heap space?

SOAs Challenges

SOA... Is it hype? What's real... and what's not? What is the right abstraction level?
