Persistence transaction-type: JTA or RESOURCES_LOCAL

Question

When i am using transaction-type: RESOURCES_LOCAL it gave the following error:

Only persistence units with transaction type JTA can be used as a container managed entity manager.

My persistence.xml file code is:

Answer 1

No, with transaction type RESOURCE_LOCAL , you have to manage database interaction not the container.

You can inject EntityManagerFactory through @PersistenceUnit & then can retrieve EntityManager from it.

All the database transaction will be managed by you & can't inject EntityManager through @PersistenceContext .

Try to go through documentation related to JTA, RESOURCE_LOCAL, CMT, BMT etc. will help to understand more clearly.
