Hi there!
I am quite new to Hibernate (if I do something very stupid)

I code agains a legacy database with composite keys. I then run the application... but the object then contains no data... I can see from the log that i record was returned (with the correct data). What am I doing wrong??

Here is the code snipped:

===START===============
//HIBERNATE
Session newSession = HibernateUtil.getSessionFactory().openSession();
DocumentHeaderID dhid = new DocumentHeaderID("6 ASU BP 001","1.00");
System.out.println("BEFORE LOAD");
DocumentHeader dh = (DocumentHeader)newSession.load(DocumentHeader.class, dhid);
System.out.println("AFTER LOAD");
System.out.println("DOC_CDE = " + dh.getDOC_CDE());
===END================


The log for this code looks like this:

===END================

The last sys out confrims the NULL value. But the log says i record wqas returnd... how come this data does not end up in my "dh" object?

Appreciate!
Giovanni

Problem solved!!
