Error creating bean with name 'myEmf' -- javax.naming.NameNotFoundException: myPersistenceUnit

I'm trying to inject the EntityManager in the DAO classes.

But I get this error during server initialization (WildFly 10.0.0).


18:35:57,318 ERROR [org.springframework.web.context.ContextLoader]
(ServerService Thread Pool -- 60) Context initialization failed:
org.springframework.beans.factory.BeanCreationException: Error

UserDAO.java

@Repository
public class UserDAO {

@PersistenceContext
private EntityManager entityManager;

...

}


What's wrong?

Answer

In your root-context.xml the reference is wrong.

jndi-name="myPersistenceUnit"

The correct one is

jndi-name="java:/MyDS"

Your server knows the second one, not the first one.
