The 1 log entry explains the log format ..

The TransactionContextet keep in prepare state because the WorkspaceInfo
acquires the Lock and will it realese on commit but
a Deadlock occurs.
I hope i have explained it to understand otherwise i will explain it to the
"day" guys in german ;-)

> Issue Type: Bug
> Components: jca
> Affects Versions: 1.2.1
> Environment: Websphere 5.1.1 J2C Adapter
> Reporter: Claus Köll
> Attachments: 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.
