I'm running JBoss 4.0.4 and running in to no end of problems getting my first attempt at J2EE code up and running. I've ridden circles of try to start the debugger, crash on an exception, search for help on exception, and implement fix for most of the day. Now I've run into one that I can't find any information about:

That turned out to be a simple matter of commenting out the JTA transaction factory initialization in the hibernate.cfg.xml, but now I'm getting into the "nuts'n'bolts" of debugging the actual HQL.

I have a very simple query method:
Code:
   public AdvDbImUserBean getByImUserNameIdx(
      String   argUserName )
   {
      Session session = HibernateSessionFactory.getSessionFactory().getCurrentSession();
      Query qry = session.createQuery(
            "select o from AdvDbImUserBean "
         +   "where"
         +      " UserName = :parmUserName" );
      qry.setParameter( "parmUserName", argUserName );
      AdvDbImUserBean rec = (AdvDbImUserBean)qry.uniqueResult();
      return( rec );
   }


But I'm getting an IllegalStateException from Hibernate that baffles me, as the mappings for AdvDbImUserBean ran successfully only moments earlier.

*sigh* Nothing more than a syntax error. HQL should have skipped the "select o" portion.

Now to figure out how to turn on debug logging of the generated SQL so I can see what PostgreSQL is complaining about.
