[jboss-user] [JBoss Seam] - NPE when accessing EM with Seam-managed transactions

Saturday, 16 June 2007

Hi,

I've been trying to persist an entity to DB, but I'm unable to get the
seam-injected entity manager to work for me.  I get errors even when trying to em.clear()
and em.flush() so I think I have some fundamental problem.  Below is the error I get when
I call em.clear() from my view page.  The action listener call fails with EJB transaction
roolback, which seems t be caused by a NPE.  I'm not sure where the NPE is coming
from.  Maybe the entitymanagerfactory can't be found?  Maybe my analysis is way off
base.  :)  Any help is greatly appreciated!

Stack:  JBOSS AS 4.05
Seam: 1.1
Hibernate: 3.2
also with myfaces / facelets / ajax4jsf

In the log I see:
