GWT, CDI and Errai at Jazoon

If you happen to be at Jazoon this year and you are interested in GWT, CDI and Errai then these sessions may be interesting to you:

Patterns and Best Practices for building large GWT applications
Tuesday, 1 June 2010, 14:00-14:50, Arena 3

In this presentation we’ll see how to organize a nontrivial GWT application. We’ll go through the lessons learned in a real world project and take a look the complete development lifecycle and best practices that go beyond what GWT has to offer out-of-the-box. This talk does focus on modularity of GWT applications and how to overcome the burdens of compile-time linking. We’ll talk about client side patterns and server side implementation options and explore different approaches that allow for quick turn around times without sacrificing maintainability.

GWT, CDI and JAX-RS: A match made in heaven
Tuesday, 1 June 2010, 15:00-15:50, Arena 3

Every non-trivial GWT application requires integration with the server side. While GWT itself ships with the integration capabilities (i.e GWT RPC) it doesn't go beyond that. Developers have to decide how to build the backend to their GWT applications. While freedom of choice is a good thing, it doesn’t always lead to a good decision. In this session we’ll look at two options, JSR-299 [1] and JSR-311 [2], both part of the EE6 specification and see how they interplay with GWT. We'll discuss the use cases and justifications for each technology see how they are applied in practice by looking at some code examples.

[1] JSR-299: Java Contexts and Dependency Injection for the Java EE platform (CDI) is the new Java standard for dependency injection and contextual lifecycle management.

[2] JSR-311: A that specification defines a set of Java APIs for the development of Web services built according to the Representational State Transfer[1] (REST) architectural style.

  1. Sounds very interesting! Is there any chance that there will be videos of these sessions?

  2. unfortunately not. but I've out the slides online. if you have specific questions, just send to the users list.
