Sessions at Devoxx 2010 on Monday 15th November

Seam is a powerful open source development platform for building rich Internet applications in Java EE, now rebuilt on JSR-299: Contexts and Dependency Injection for Java EE. JSR-299 is an elegant set of new services that include dependency injection, contextual lifecycle management, configuration, interceptors and event notification. While these services are familiar, the innovative use of meta-annotations is uniquely expressive and typesafe, and a significant step forward from Seam 2. The implementation of this new programming model is provided by Weld. Seam extends the CDI programming model by providing portable enhancements, extensions and integrations that tie technologies such as Java Persistence 2 (JPA), Enterprise JavaBeans (EJB 3.1), JavaServer Faces 2 (JSF), Business Process Management (BPM), business rules (Drools), reporting (PDF and Excel), security and e-mail templates into a unified full-stack solution, supported by sophisticated tooling.

In this session, Pete Muir and Dan Allen, two of the lead Seam developers, detail the state of the union for Seam 3.

We'll cover how it's being reachitected on JSR-299, cover its new modularized and autonomous infrastructure and provide an overview of features, both migrated and new.

Members of the Arquillian team unveil the missing link in enterprise Java development: simple, portable integration tests. For many, working in enterprise Java has long been an arduous undertaking because of this void. While development life is simple with unit tests and mocks, they only take you so far. Eventually, you need to validate how your components interact and operate in their intended environment--you real need integration tests. Yet, writing integration tests has meant assuming the burden of bootstrapping all or part of your infrastructure. That's time lost and it places a mental barrier on testing. We'll teach you how to get out of this jam and make the transition from unit to integration tests without any trouble at all.

This lab puts Arquillian in your toolbox. Arquillian is a container-oriented testing framework layered atop TestNG and JUnit that makes testing enterprise Java applications easy. It does so by bringing your test to the runtime rather than requiring you to manage the runtime from your test. Picking up where unit tests leave off, Arquillian enables you to test real components that rely on real enterprise services in a real runtime.

What’s the secret? This lab gives you an appreciation for how Arquillian simplifies integration testing by providing a component model for tests, just as Java EE 5 simplified server-side programming by providing declarative services for application components. We'll study the test component model, which consists of container lifecycle management, test enrichment (dependency injection), container deployment and in-container test execution. Using a component model means your tests are portable and able to move between different environments, from single embedded or remote to multi-server to multi-cloud nodes.

We'll begin by introducing you to the fluent API provided by ShrinkWrap that is used to package a test archive, giving you fine-grained control over which resources are available to be tested. We'll show examples of how the test archive is deployed and executed inside standalone, embedded and remote containers. You'll witness how RPC-style (or local, if applicable) communication between the test runner and the container negotiates which tests are executed and reports back the results.

You'll walk away confident that you can:

1. write integration tests just as you would a unit test and
2. run those tests in multiple environments (containers)

Join this lab to learn how simple and powerful Java enterprise testing can be.

Java EE is already the perfect solution for complex business/enterprise systems, and the improvements in JavaServer Faces 2.x provide the perfect chance to reach out to the consumer and small business market; JSF is easier to use than it's ever been before, now making it accessible to businesses of all sizes. In order to complete the user-experience, however, one must take extra steps to ensure that users see exactly the right information at the right time, and in a form that is welcoming. URL-rewriting is beneficial in any project (small and large,) and this tools session will present why "pretty, bookmark-able URLs" are important for client-facing applications, building trust, creating clean, consistent, intuitive client interactions on the web.

Attendees should expect an overview covering the basics of inbound/outbound URL-rewriting, parametrization, and navigation - important principles that target the highly discriminating web-users found everywhere today. They will also be presented with a case study of the Parlays.com HTML 5 application, in which an existing JSF application is transformed from using standard URLs with query parameters, to using logical, well-structured, human-readable URLs (with PrettyFaces path-parametrization).
