Question

I have following POJO`s:
– Company

• Node
  (nodeID, company)

• User
  (userID, node)

I want to create where clause(via Criteria) which will return to me every user for given company. Something like …

Criteria criteria = session.createCriteria(User.class)
criteria.add(Restrinctions.eq("node.company", someCompanyObject);

But this is not working, so is it possible to do this with criteria class or should use
HQL/SQL?

Thanks in advance!

The hibernate documentation says:

By navigating associations using createCriteria() you can specify constraints upon related entities:

List cats = sess.createCriteria(Cat.class)
    .add( Restrictions.like("name", "F%") )
    .createCriteria("kittens")
        .add( Restrictions.like("name", "F%") )
    .list();

Transposed to your problem:

Criteria criteria = session.createCriteria(User.class) 
    .createCriteria( "node" )
    .add( Restrinctions.eq( "company", someCompanyObject) );
