Upgrading to Seam 2.0.1 JBoss 4.2.2 GA
Hi,
I'm trying to move my webapplication from Seam 1.2.1 / JBoss 4.0.5 to Seam 2.0.1 / JBoss 4.2.2, but I'm experiencing great trouble with seam's managed persistence context (SMPC).
If I try to inject the EntityManager
into my SFSBs and if their scope is CONVERSATION scope, then I always get an EJBTransactionRolledbackException for no apparent reason.
If I remove the following two lines from my SFSB, then the EJBTransactionRolledbackException is not raised anymore, but of course that does not help much:
@In(create = true) EntityManager entityManager
That's why I know that it's a problem with injecting seam's managed persistence context into the SFSBs. Unfortuanetly the Exception itself gives no further clues.
What is interesting is, that I can inject the EnityManager, if I set the scope of the SFSB to SESSION. Then I can inject the EntityManager without any problems and use it, too.
For example, the following code works fine:
@Name("simpleAction")
@Stateful
// SESSION SCOPE IS OK! WHY CAN'T I USE CONVERSATION SCOPE?
@Scope(ScopeType.SESSION)
public class SimpleAction implements BasicSimpleAction
{
@In(create = true)
EntityManager entityManager;
...
I really have no clue why this gives me trouble in Seam 2.0.1. I have checked all the configuration files many times today, and went through all the examples until I discovered that it's those two simple lines causing the woe.
I appreciate any advice, because I really dont't know what to do anymore. I have scanned the server.log for errors and warnings and got this, which however, does not really help me either:
