I've been trying for two days to get a Seam app, with some very simple persistent EJB3 entities, to run within JBoss 4.2.1. Is this even possible? If anyone has an example of a .ear file that uses Seam that will run in JBoss 4.2.1 please let me know. I'm also trying to use Seam-gen. I'm making some progress but the resulting seam-genned app needs lots of work to run within JBoss 4.2.1. Right now I'm stuck getting a NullPointerException: jboss.j2ee:ear=myproject.ear,jar=jboss-seam.jar,name=Dispatcher,service=EJB3 | java.lang.NullPointerException | at org.jboss.ejb.txtimer.DatabasePersistencePolicy. | listTimerHandles(DatabasePersistencePolicy.java:165) Any ideas?
