------------------------------

We can rewrite the method as like this....


 public Session currentSession()
        throws HibernateException
    {
        TransactionManager transactionManager = factory.getTransactionManager();
        if(transactionManager == null)
            throw new HibernateException("No TransactionManagerLookup specified");
        Transaction txn;
        try
        {
            txn = transactionManager.getTransaction();
            if(txn == null)
                throw new HibernateException("Unable to locate current JTA transaction");
            if(!JTAHelper.isInProgress(txn.getStatus()))
                throw new HibernateException("Current transaction is not in progress");
        }
        catch(HibernateException e)
        {
            throw e;
        }
        catch(Throwable t)
        {
            throw new HibernateException("Problem locating/validating JTA transaction", t);
        }

	Session currentSession = null;
  	if ( txn != null && !JTAHelper.isInProgress( txn.getStatus() ) ) {
	               throw new HibernateException( "Current transaction is not in progress" );
	    } else if (txn != null) {
	              currentSession = ( Session ) currentSessionMap.get( txn );
	    }

        if(currentSession == null)
        {
            currentSession = buildOrObtainSession();
            try
            {
                txn.registerSynchronization(buildCleanupSynch(txnIdentifier));
            }
            catch(Throwable t)
            {
                try
                {
                    currentSession.close();
                }
                catch(Throwable ignore)
                {
                    log.debug("Unable to release generated current-session on failed synch registration", ignore);
                }
                throw new HibernateException("Unable to register cleanup Synchronization with TransactionManager");
            }
            currentSessionMap.put(txnIdentifier, currentSession);
        }
        return currentSession;
    }

> This is my hibernat.cfg.xml file which i have been using for my app. me trying out an J2ee Application within an weblogic 9.0 . As my config denotes its exactly true.When WeblogicTransactionManagerLookup tries to look out for tranaction within JTASessionContext within currentSession() method , it returns due to the following line.
> if(txn == null)
> {
>   throw new HibernateException("Unable to load JTA Transaction);
> }
> this line didn't allow to proceed within the method to create an new session. Its an bug with JTASessionContext. Correct me if iam wrong.
