Is Seam compatible with JBoss 4.2.1?

[smokingapipe]

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?

I tried several of the examples of the seam book (the one by Michael Yuan) on 4.2.1 without any problems.
(with Java 6 on Suse Linux, but that shouldn't matter)

you can find the examples here:

Yesterday I ported my seam application to JBoss AS 4.2.1GA. I have setup the libraries. I forgot to place my datasource (*-ds.xml) file in the deploy folder but that was easily fixed. So, no problems with me either...

Here an excerpt from the log that I think matches yours:
