I am relatively new to hibernate. I am evaluating hibernate as O/R tool for my company. I have a legacy database and I am trying out a simple load operation using composite key. I have a primary class created by middle gen

Code between sessionFactory.openSession() and session.close():
dictPk = new DictionaryPK();
System.out.println("After PK1");
dictPk.setDictCode(dictCode);
System.out.println("After setDictCode"+ dictCode);
dictPk.setSubCode(subCode);
System.out.println("After setSubCode"+ subCode);
Dictionary dict = new Dictionary();
System.out.println("After dict init");
dict.setComp_id(dictPk);
System.out.println("After setComp_id dictcode="+ dict.ge
tComp_id().getDictCode());
//dictData = (Dictionary) session.load(Dictionary.class,
dictPk);
dictData = (Dictionary) session.load(Dictionary.class,di
ct);
