Just want to ask you all,

I have this code, this is run well on hb 2.1.7

Criteria crit = session.createCriteria(User.class);
crit.add(Expression.eq("username", new String(username)));


I read the Migration tips from issaco to change the Criteria object become Expression.

like this

Expression crit = session.createCriteria(User.class);
crit.add(Expression.eq("username", new String(username)));

but the add still problem, not found.


i find that there is a Criterion object, what kind of case I can use to implement Criterion.

and what is the replacement of add of my criteria which I found in hibernate 2.1.7

Thanks

Hi,

There is not much of a change as u have done, Its simple as that in Hibernate 3.x,

i.e)
Criteria crit = session.createCriteria(User.class);
crit.add(Expression.eq("username", new String(username)));
List userlist = crit.list();
