Typically you want more separation. You want the DAO layer interacting
directly with the database, you want the service layer doing business
logic, and you want the web layer to connect the web pages with the
business logic. So I wouldn't suggest having any action directly
utilizing DAOs, and I wouldn't suggest that you ever make the service
layer and the DAO layer synonymous, both of which you appear to be doing...

So which of those lines is #42?
If I had to guess I'd say it's the session.createQuery() call if you
aren't getting your session initialized correctly...what's the println show?

Posted by Martin Gainty <mg...@hotmail.com>.
EntityManager em = factory.createEntityManager();
<snip>
//create the query from the EntiryManager
Query q = em.createQuery( "select i from " + Item.class.getName() + " i where i.name like :itemName" );
String itemName="foobar"; //itemName cannot be null
q.setParameter( "names", itemName );
i dont see your EntityManager?
