Have you ever had an idea on how some web or desktop UI should look and needed to tell someone about ?
Your text explanations would be misunderstood or you were just too lazy to even write it down or use any of the many useless expensive tool to make it ?
If there's one thing that we really want to get right as Web Beans goes from Public Draft to Proposed Final draft, it's integration with the Java EE platform. Up to this point, most of the work we've been doing as an EG was focused on nailing down the programming model, the semantics of the Web Beans services, and the behavior of the Web Bean manager. We've been writing the spec to assume that Web Beans implementations should be pluggable between different Java EE containers, because this is a direction that a lot of folks in the Java EE community believe that the EE platform should move in, and because we would like Web Beans to help show the way for other specifications such as EJB, JTA and perhaps even Servlets (note that JPA and JSF already support this).
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.
