About this task
Step 1 towards the goal:
Implementing EJB 3.x applications
Procedure
There are no migration issues associated with using
EJB 3.x beans. Existing applications continue to run as-is and compile
without error. The EJB 3.0 and 3.1 specifications have deprecated
the use of EJB 1.1 style entity beans. You are encouraged to start
migrating to Java™ Persistence API (JPA) or JDBC as a replacement
for entity beans.
