I am very new for portal and portlet and I am interested in this stuff. I just read through JSR 168 and I am wondering what's the next step in terms of being able to build a portal using JBoss. I installed JBoss 4.0.3SP1 and portal 2.2. It looks I can access the portal. But my question is that if there are some tutorials in JBoss that will teach you step-by-step how to build your portal using JBoss?
