    EJBs and Transactions

    Nigel White Newbie

      I'm not too sure abuot "Transactions", I thought they were something to do with databases, but they appear to be something to do with EJBs....

      Anyway, in one of my EJBs, I create a HibernateEntityManagerFactory. The createEntityManagerFactory() call fails with

      13:10:09,203 ERROR [SchemaUpdate] could not complete schema update
      java.sql.SQLException: You cannot commit during a managed transaction!
       at org.jboss.resource.adapter.jdbc.BaseWrapperManagedConnection.jdbcCommit(BaseWrapperManagedConnection.java:496)
       at org.jboss.resource.adapter.jdbc.WrappedConnection.commit(WrappedConnection.java:334)
       at org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:129)

       at org.hibernate.ejb.Ejb3Configuration.createEntityManagerFactory(Ejb3Configuration.java:410)


      Something to do with the EJB starting a Transaction? How do I get the call to createEntityManagerFactory NOT to use a "ManagedTransaction"???
