Hi,
I am developing an web base project.In my project i am calling hibernate with stateless session bean.
That is

stateless session bean calls hibernate then hibernate store data which i want to store in database.

So to do what should i do.I any one have sample code plz post it as early as possible.

Thanks in advance

I do not have an answer to your problem. I am new to Hibernate myself. I am just wondering about integrating Hibernate and EJB. I thought they were both trying to address the same problems and therefore competing products.

Is this a requirement from a so called "architect" or are you choosing to do this yourself?

Hi

Hibernate and EJB aren't adressing the same problem and therefore aren't competing products. EJB uses Java Persistence for Persistence purposes and Hibernate is an Java Persistence Provider.

I think there are severall ways to use Hibernate with EJB:
1) Use only the Java Persistence stuff. So let the application server inject an EntityManager into your Session Bean. Use this EntityManager to persist Entities. In this case Hibernate works in the background for you, so you aren't bound to Hibernate as persistence provider.
2)If you want to use the Hibernate Session instead of the EntityManager, you can get the Hibernate Session from the EntityManager. Do it this way: Session session = ((HibernateEntityManager)entityManager).getSession();
3)If you are using the application Server JBOSS, the Session can be injected directly into your bean by JBOSS.

Sorry that I haven't written down any code examples, but my book "Java persistence with hibernate" (one of my best books) is still at my company. And without the book (I'm very new to Hibernate and Java persistence) I wouldn't be sure that the code I wrote down is correct.

I hope my hint will help you

Thanks for quick response

I am new in hibernate tech. So i am not getting what u want to suggest. Can give me sample code if u have any.
I will be very thankful for it.
waiting for reply.

Thanks in advance

Hi!

To let your application server inject an EntityManager in your bean write:


If your are using jboss, the session can be injected directly:


If your aren't using JBOSS but you want to work with a session instead of an entiymanager do it right this:
