Claus Köll commented on JCR-769:
--------------------------------
I have changed the code in the XASessionImpl to store the TransactionContext
with the GlobalTransactionId as Key in the txGlobal Map
instead the whole Xid Object to get only one TransactionContext Object during
the whole XATransaction
This works fine for me and i think this is the right way.
I have traced the entire XA Transaction.
As you will see the problem with the lock in the WorkspaceInfo Object still
occurs without my Patch !

The next Problem is now that the commit Method from the first Session will
delete the TransactionContext from the Cache and this is very bad because the
second Session
will not find the TransactionContext in the Cache in its commit Method, so a
XAException(XAException.XAER_NOTA) will occur.
I hope this stack will help to understand the problem.

> Issue Type: Bug
> Components: jca
> Affects Versions: 1.2.1
> Environment: Websphere 5.1.1 J2C Adapter
> Reporter: Claus Köll
> Attachments: patch.txt, stacktrace.txt
>
>
> I'm using the Jackrabbit 1.2.1 JCA adapter and trying to access in a
> SessionBean-Method with Container Transaction a Workspace with 2 different
> Credentials.
> The Method takes about 400ms to finish but no commit on TransactionContextr
> occurs (Debugging ..) only the prepare was called 2 times .
> The Container hangs on the PostInvoke Method about 5 seconds and then i get a
> "javax.transaction.xa.XAException"
> with the Warn Message: Transaction rolled back because timeout expired
> The code ..
> Context ctx = new InitialContext();
> Repository repository = (Repository) ctx.lookup("java:comp/env/jackrabbit");
> Credentials credentials = new SimpleCredentials("user1",
> "password1".toCharArray());
> Credentials credentials2 = new SimpleCredentials("user2",
> "password2".toCharArray());
> Session session1 = repository.login(credentials, "default");
> Session session2 = repository.login(credentials2, "default");
> Session1 adds a node to the workspace .. and with the session2 i do nothing
> except the login !
> If i make no second login the Method works fine.
