I've got Embeddded JBoss from the JBoss_5_0_0_Beta3 tag correctly running the Seam testsuite. The only known problem is with JMS:
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=125194
but no one from messaging has been able to help.
The branch is here
https://svn.jboss.org/repos/jbossas/branches/EMBEDDED_JBOSS_BETA3/
I would therefore like to do a beta3 release of Embedded JBoss in a couple of days.
Thanks to Scott, Clebert and Kabir we got past the JMS NPE.
I'm still getting an exception from JMS

Even though the exception is thrown, JMS still seems to work correctly (tests pass).
