Wrong transaction association

[jbossacm]

I'm having trouble with transactions in JBOSS 4.0

I have the following code to create my transaction within a Sateless Session Bean:

UserTransaction transaction;
transaction = (UserTransaction) ctx.lookup("UserTransaction");
transaction.begin();

It seems as though when the begin statement is called, I get the following error:

java.lang.IllegalStateException: Wrong transaction association: expected TransactionImpl:XidImpl[FormatId=257, GlobalId=DELL001/32, BranchQual=, localId=32] was null

Can anybody tell me what's going on? I can't seem to find any information in any forum.

Thanks so much.

OK, it seems I found out what was wrong.

I'm using CMT and I was trying to obtain an explicit transaction inside a Stateless Session Bean.

The thing is that I'm performing a migration from Weblogic to Jboss and in Weblogic I needed to obtain this transaction explcitily, if not, it did not work. Whereas in Jboss it seems to violate the EJB specification.

Now that I have eliminated the explicit user transaction, it works like a charm. The downside is that the code will not be portable.

If anybody has more insight on the subject please feel free to post.

Thanks!

I dont understand if you were using the CMT why would you explicitity get the UserTransaction Object in the SesionBean then . Can you please confirm this ?
