Class JtaEntityManager

java.lang.Object

All Implemented Interfaces:: Serializable, javax.persistence.EntityManager

public class JtaEntityManager

extends Object
implements javax.persistence.EntityManager, Serializable

The JtaEntityManager is a wrapper around an entity manager that automatically creates and closes entity managers for each transaction in which it is accessed. This implementation supports both transaction and extended scoped JTA entity managers.

It is important that extended scoped entity managers add entity managers to the JtaEntityManagerRegistry when the component is entered and remove them when exited. If this registration is not preformed, an IllegalStateException will be thrown when entity manger is used. It is important that a component adds extended scoped entity managers to the JtaEntityManagerRegistry when the component is entered and removes them when exited. If this registration is not preformed, an IllegalStateException will be thrown when entity manger is accessed.
