[Hibernate] Query by Criteria ..
Hi all, I'm new to Hibernate, and maybe I shouldn't post this question here, but I also don't think that the user-list may answer to it. Until now I used Torque, and I found very usefull the generated constants for Table and Column-names. Does Hibernate provide such a functionality? In my opinion that is a great help for developers, and is a good practive from quality assurance point of view.

Re: [Hibernate] sessionfactoryimpl.close()
Hi, We tried to do this but it requires us to un-final stuff and that is not worth it.

Why? You can call clear() on collections marked as final.
