EJB3Configuration and txStrategy

If you set your transaction strategy

Code:

            <property name="hibernate.transaction.factory_class" value="org.hibernate.transaction.CMTTransactionFactory"/>

you always get an exception ... since 'else' is executed.

Code:

      boolean hasTxStrategy = StringHelper.isNotEmpty( preparedProperties.getProperty( Environment.TRANSACTION_STRATEGY ) );
      if (! hasTxStrategy && transactionType == PersistenceUnitTransactionType.JTA) {
         preparedProperties.setProperty( Environment.TRANSACTION_STRATEGY, JoinableCMTTransactionFactory.class.getName() );
      }
      else if (! hasTxStrategy && transactionType == PersistenceUnitTransactionType.RESOURCE_LOCAL) {
         preparedProperties.setProperty( Environment.TRANSACTION_STRATEGY, JDBCTransactionFactory.class.getName() );
      }
      else {
         new AssertionFailure("Unknown PersisntenceUnitTransactionType: " + transactionType);
      }
      if (hasTxStrategy) {
         log.warn("Overriding " + Environment.TRANSACTION_STRATEGY + " is dangerous, this might break the EJB3 specification implementation");
      }

Fixed, but still this is a real bad idea to define the transaction strategy manually. You will not comply with the spec.

Great.
And thanx for the tip.

ps: txStartegy removed as it was almost similar as now by default - CMT
