Abstract:
One of the best ways to introduce Groovy to new projects and teams is to use it for Unit testing Java code. Using Groovy to unit test Java code has several advantages. You can take advantage of its concise syntax for writing tests. Groovy's dynamic and metaprogramming capabilities can be exploited for mocking purposes. In this presentation, you will learn tips and techniques to use Groovy to unit test both your Java and your Groovy code.

Abstract:
It is a very common practice to develop web applications that are use-case-oriented. This approach has a very procedural feel to it where URLs often involve imperative verbs: "showProduct," "deleteOrder," or "updateShoppingCart." While this approach has served us well, it does lead to unnatural and difficult–to–follow URL schemes. Furthermore, the direct objects of the URLs' verbs are often specified in parameters, precluding any effective caching or indexing within search engines.

In contrast, RESTful web applications tend to be more resource–oriented. Rather than focus on verbs, REST places emphasis on the nouns. RESTful URLs tend to describe the target of an operation, and rely on a fixed set of verbs (GET, PUT, DELETE, and POST) to indicate the operation itself. Moreoever, RESTful URLs identify resources, which themselves may be represented in many forms. This means that if properly applied, REST can be used not only to create a web application, but to also define an API that can be used to access resources that are represented as JSON, Atom, RSS, XML, and/or (of course) HTML.

With the recent release of Spring 3.0, the Spring MVC web framework affords many opportunities for building RESTful applications. This includes a new set of annotations to support defining resource–oriented URLs, and a new REST client template for consuming RESTful APIs.

In this session, we'll look at the latest features of Spring 3.0's MVC framework, with an emphasis on building RESTful web applications. You'll see how Spring 3.0's new @PathVariable annotation can be used to develop controllers that respond to resource–oriented RESTful URLs, and how ContentNegotiatingViewResolver can turn a user–facing web application into a powerful web–based API. We'll explore other ways Spring 3.0 supports working with REST, including how to write REST clients.

The slides from Feb 10th are on SlideShare here. And the Roo project is here.

This session will survey a wide range of tools across the Java space. We'll look at utilities such as VisualVM, jstatd, jps, jhat, jmap, Eclipse Memory Analyzer, jtracert, btrace and more.

Open Source is not just a suite of libraries you consume within your application, but now reaches into the space of tools to help you troubleshoot and improve your applications. The price of these tools eliminates barriers to their use and their open source nature allows you to mix and match them into compositions that work well for your application's unique debugging needs.

These tools will help you peel away layers of your application to expose bugs and performance ceilings. We'll interactively analyze the heap and garbage collection cycles of both local and remote applications, take snapshots of heap, query the heap for heavy usage, leaks and augment running code without a reboot and without breaking a sweat. After attending, you'll never look at Java debugging the same way again.

The slides from March 10th are here. And the demo scripts are here.

Abstract:
Building highly interactive software that users love to use is usually a challenging endeavor. However, the open source Flex SDK and Java are a perfect combination of technologies for building very rich and highly interactive software for the Web and the desktop. The communication between the Java back–end and Flex front–end can utilize a number of different communication protocols, but the easiest and best performing is the open source BlazeDS library. This session covers the fundamentals of using Flex, Java, Spring, and BlazeDS to build rich and highly interactive software for the Web and the desktop.

Much like his love for climbing mountains, he enjoys programming because it provides endless new discoveries, elegant workarounds, summits and valleys. His adventures in climbing have taken him many places. Likewise, technology has brought him many adventures, including: Pascal and Assembly back in the early '90s; Perl, HTML, and JavaScript in the mid '90s; then Java and many of its frameworks beginning in the late '90s. Today, he primarily uses Flex to build beautiful front–ends for Java based back–ends. Prior to Adobe, James built a rich marketing and customer service portal for Pillar Data Systems.

Abstract:
Ehcache is an open source, standards–based cache used in a wide array of applications to boost performance, offload the database and simplify scalability. Ehcache is robust, proven, and full–featured, and this has made it the most widely used Java–based cache.

Chris will walk through the Spring Pet Clinic as an application example and show us how to tune it for maximum performance, both when using Hibernate and when caching result sets directly.

He will show us benchmarking tests on the comparative application performance of Ehcache EX 1.8 versus MySQL, Memcached and a leading In–Memory Data Grid, including the impressive performance increases from the latest Terracotta 3.2 Server Array.

Finally, Chris will also discuss some upcoming features in Ehcache 2.0, such as JTA, bulk loading, the new Hibernate 3.3 provider, and write–behind.

Abstract:
The Java Persistence API (JPA) has really taken over the Java development world, and is now recognized as the enterprise standard for object–relational persistence. But with so many people using JPA, the feature cracks were starting to show. Some found that pieces were either missing or not fully specified in the 1.0 release.

JPA 2.0 has filled in the feature gap, and introduced many of the additional features that developers were asking for. Mike will examine where the 1.0 standard stopped, and where the new 2.0 release continues on. He'll offer a few tricks to using some of the new features, and when it may be appropriate to use them. He'll show how to specify advanced object–relational mappings and collections, illustrate how to mix access modes, describe some new locking options, as well as explain how to create typed queries with or without the new typed criteria API.

The slides from June 9th are here.

Java Contexts and Dependency Injection (CDI) is the new dependency management system introduced in JSR 299. Formerly known as Web Beans, CDI brings the pioneering work done in frameworks such as Seam and Guice into mainstream of standards–based Java development. CDI is included in the Java EE 6 platform, and serves as the unifying component management technology across the entire EE platform. In this talk, I'll introduce the basic concepts of CDI, and explain how you can get started using Weld, the CDI reference implementation.

Abstract:
Software engineering as it's taught in universities simply doesn't work. It doesn't produce software systems of high quality, and it doesn't produce them for low cost. Sometimes, even when practiced rigorously, it doesn't produce systems at all.

That's odd, because in every other field, the term “engineering” is reserved for methods that work.

What then, does real software engineering look like? How can we consistently deliver high–quality systems to our customers and employers in a timely fashion and for a reasonable cost? In this session, we'll discuss where software engineering went wrong, and build the case that disciplined Agile methods, far from being “anti–engineering” (as they are often described), actually represent the best of engineering principles applied to the task of software development.
