Book: Java Persistence with Hibernate (there is an ad for it (most of the time?) on the top of the page.

Read the Forum, answer questions.

Get working on a real project with real requirements (prevents you from using shortcuts when you hit problems).

Hi Jens,
I found in hibernate site like Hibernate Core,Hibernate Annotations,Hibernate Entity Manager,Hibernate Shards,Hibernate Validator,Hibernate Tools...In these concepts which concepts are very important, which are optional.Can you suggest me that?

To get you started before you buy the book, there is an official tutorial:

http://www.hibernate.org/hib_docs/v3/re ... orial.html

If you follow that you can get your first application up and running very soon.
I would focus on understanding Hibernate Core first - and then have a look at the other hibernate projects if you need a solution for a specific problem.
(Example, you want to search your persistent objects -> take a look at hibernate search!)

Core ist the core so you can't do without it. Start here

After that it depends on the direction you are interested in:

Annotations: do you configuration with Annotations instead of XML. I strongly recommend it, but ther might external constraints that prevent this

Hibernate Entity Manager: Closely related to Annotations. Its about JPA, a offical standard wich is implemented by Hibernate Annotations. Annotations is a little more powerfull/flexible. It's your call: do you want power? Or Standard?

Hibernate Validator is realy small and nice. Definetly read the documentation it is less the 10 pages long.

Hibernate Shards, Hibernate Search Hibernate Tools: Very specialised. When you have specific problems to solve google for them you'll might end up on pages about these projects. If not just ignore them for now.
