How to generate hibernate classes in eclipse ide? Can any body help in giving step by step procedure.

That's too much information to explain in this forum so you're going to have to do some reading like the rest of us have. :)

It's been awhile since I've worked with Hibernate but check out Hibernate Tools. There is a plugin that will reverse engineer a database and lots more. There's also several books about Hibernate at OReilly.com that can help you as well.

Good luck.

You mean in Eclipse or in Java ?
Why would you want to hibernate in Eclipse ?
