I have the following error when I try to start a transaction with a postgres database.

java.sql.SQLException: ERROR: SET AUTOCOMMIT TO OFF is no longer supported

My code has a wonderful behaviour until a few moments. The only thing that I made is to install JBoss. The code always works fine with Tomcat 5.0 with jdbc and spring. Althought I have installed JBoss it´s not running.

The part of code in SQLException is thrown:

      DefaultTransactionDefinition def = new DefaultTransactionDefinition();
      def.setPropagationBehavior(TransactionDefinition.P ROPAGATION_REQUIRED);

      PlatformTransactionManager ptm = transactionTemplate.
                                                        getTransactionManager();
      TransactionStatus status = ptm.getTransaction(def);

Please for your help anybody
