One of the more exciting features of JBoss Seam 2.0 is that it can be used without JSF.
Here is a sample project using Seam 2.0 with Apache Wicket 1.3 instead of JSF.
Additionally:
1. Runs out of the box in Glassfish V2. (Not tested in JBoss AS)
2. Uses default Glassfish Toplink Essentials instead Hibernate.
3. Is a Netbeans 6.0 project. (100% Ant compatible)
There is also a well layered architecture diagram for this specific scenario.
