Code between sessionFactory.openSession() and session.close():
Criteria crit = session.createCriteria(UserReport.class);

crit.createAlias("user", "user")
.createAlias("user.customer", "cust")
.createAlias("report", "bankReport")
.createAlias("bankReport.bank", "bank")
.add(Expression.eq("user.id", new Long(user)))
.createCriteria("cust")
.add(Expression.eq("id", new Long(customer)))
.createCriteria("bank")
.add(Expression.eq("id", bank));
it = crit.list().iterator();

In HQL, here is what I am trying to do:

String query = "from UserBank as user where user.bankReport." +
"bank.id = ? and user.id = ? and user.customer.id = ?";

If I need to post the mapping files, I will, however that's alot of stuff to post. I'm hoping it's just my use of the criteria API. Any help would be appreciated. Thanks in advance
