All Implemented Interfaces:

org.eclipse.persistence.sessions.ExternalTransactionController

public class JtaTransactionController
extends org.eclipse.persistence.transaction.JTATransactionController

An implementation of EclipseLink's ExternalTransactionController which will utilize the JTA TransactionManager being used by the KRAD application.

It locates this via a call to Jta.getTransactionManager(). So the application must ensure that it has configured and setup JTA properly within it's application environment.

The superclass for this class, which is part of EclipseLink, attempts to invoke the acquireTransactionManager() from the default contructor. So an attempt will be made to acquire the JTA transaction manager as soon as an instance of this object is created. This means that it must be ensured that JPA is enabled prior to the creation of an instance of this controller class.
