Man, Hibernate has been making my head ache. I just can't get my brain around the whole of it. I started writing my own DAO out of frustration (which isn't too hard/complicated) so what's the big deal with Hibernate? I only want to map SQL to Java and back.
However, while reading through Jakarta Struts Cookbook I came across iBATIS - what a piece of cake.
If you're looking for a DAO, and are wondering WTF Hibernate is all about, try looking at iBATIS (now an apache project) instead. It is simple. Apparenly, it's not a full blown ORM, but I don't want a full blown ORM. Who does?
