accessing jpa using in session bean

[bhavsar.er]

Hi,

Please note that we are having all stateless session beans at present in our application. we are going to use JPA for db activity. we are planning to use @PersistentContent entitymanager. is it good idea to use it directly in session bean or i need to create dao layer again which will be having @PersistenceContext. As per my understanding @PersistenceContext can not be used in other than container managed, in that case i need to expose my dao layer as session bean ? Kindly provide me the solution. Thanks.

Hi Paresh,

We faced a similar question a while back. I would be also be interested in any best practice recommendations on using EJB3 JPA.

Have a look at Spring JPA (http://static.springsource.org/spring/docs/2.5.6/reference/orm.html). You can easily integrate Spring into your jboss container, then you are not dependent on container managed components for your JPA injections.

We have documented our experiences with integrating spring here : http://community.jboss.org/wiki/AnexperiencewithIntegratingSpringandJboss.
