Migrate from EJB 2 Entity Bean to EJB3

Question

I am having some entity beans created in EJB 2.0 and now I need to migrate to EJB 3.x, but I've studied that use of entity beans are changed in EJB 3.x and they are using JPA instead.

Where can I find solution to actuate my beans to be comfortable with EJB 3.x?

IntelliJ EJB refactoring tools might prove to be useful: http://www.jetbrains.com/idea/webhelp/migrating-to-ejb-3-0.html

I belive there are some for Eclipse too.

just for future reference, I recommend the following link: http://what-when-how.com/enterprise-javabeans-3/migrating-cmp-2-entity-beans-to-the-ejb-3-jpa-part-1/

And there's also part 2 on the same site as well as migrating session beans and MDBs. I used them and found them very helpful and useful.
