Hello,

I am seeking insight into an error I am getting using Hibernate. Any help will be greatly appreciated. I am using Hibernate 2.1.4 on Windows XP to query DB2 version 7.2 sitting on MVS (OS390). When I execute the following code:

Code:
SessionFactory factory = cfg.buildSessionFactory();
Session s = factory.openSession();
Transaction tx = null;
List list = null;
try {
                tx = s.beginTransaction();
   Criteria crit = null;
                s.createCriteria(CrsOffer.class)              .add(Expression.eq("comp_id.year", yearIn))
     .add(Expression.eq("comp_id.term", termIn))
     .add(Expression.eq("comp_id.camp", campIn))
     .add(Expression.eq("comp_id.sect", sectIn));

   list = crit.list();
                CrsOffer crsOffer = (CrsOffer)list.get(0);
                tx.commit();
                Set set = crsOffer.getCrsReqCodes();
} // end try


I get the SQL ERROR 302 which my DBA says is probably caused by the host variable being used is too large. I used middlegen to create my mappings and the hiberbate tools to generate the java classes. Below is the stack trace and following that are the rerlevant mapping files.

I have tried a new scenerio using different tables which have the same characteristics as the ones mentioned above and I get the same result:

Code:
