how to do paging using hibernate 3.0
an example source code

So far the only example of paging that I have seen is:

Query query = session.createQuery(queryStr);
query.setMaxResults(10);
query.setFirstResult(20);
return query.list();

of

Criteria crit = session.createCriteria(Foo.class);
crit.setMaxResults(10);
crit.setFirstResult(20);
return crit.list();

For max result you put in the number of objects you want returned (you can not use a fetch joining statement with paging) and for first result you put in the row number you want to start at. My only problem with this is all the examples I have seen so far pass in the page count and times it by the max size and use that as the starting point. What happens if your max result size changes? Then you can not use the page count times size. If you happen to come across a way to get the row count for an object after a sort was added please let me know.
