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.
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.
