      extended by oracle.adfinternal.model.adapter.toplink.JTATransactionBroker

public class JTATransactionBroker
extends TransactionBroker

This class describes a TransactionBroker that uses a JTA-shared transaction model. Instead of acquiring a UnitOfWork from the Sesssion and using isolated transaction space, this TransactionBroker always delagates to the Session to use the JTA transaction. This type of TransactionBroker is employed when the given Session indicates a shared, JTA transaction. Using a shared, JTA transaction is useful when the data control is one of many services used in a shared transaction application.
