The Seam 2.1.0.SP1 release included a new reference guide chapter describing Seam integration with GlassFish v2. As with most container integration the bulk of the work is reconciling library differences, datasources and deployment descriptor changes. Glassfish is no different in that regard, however it is much easier to integrate and work with GlassFish than some of the other containers that I written about.
The Seam distribution includes a tool named seam-gen to help you get started quickly using Seam. The tool collects information from you about your project and then uses that information to create a project structure. It can also generate a CRUD application by reverse engineering your database schema and generate various forms of stub code. In this entry, you'll learn how to get the generated project setup in Eclipse so that you can leverage the available tooling.
Kito Mann, editor of JSF Central, recorded a podcast with me a couple of weeks back. We deleved deep into the features of Seam 2.1, but also talked about the Public Review Draft of Web Beans (keep an eye on Gavin's blog for updates) and JSF2.
The 2.1 GA release was just a week ago, but a few minor issues slipped through the cracks, mostly around seam-gen. We've put together an SP1 release to address the problems. If you are using 2.1 already, I'd recommend grabbing 2.1 even if you aren't experiencing any of the issues.
