public class JTATransactionController
extends AbstractTransactionController

Purpose: TransactionController implementation for JTA 1.0

Description: Implements the required behavior for controlling JTA 1.0 transactions. Specific JTA implementations may need to extend this class when special controller behavior is necessary.

The JTA TransactionManager must be obtained and set on the instance in order for a Synchronization listener to be registered against the transaction. This can be done either by extending this class and defining acquireTransactionManager() to return the manager for the server, or by using this class and explicitly calling the setTransactionManager() method on it after the fact. e.g. TransactionManager mgr = controller.jndiLookup("java:comp/TransactionManager"); controller.setTransactionManager(mgr);

If a different listener needs to be used for synchronization, the SynchronizationListenerFactory should be set on the controller instance. The listener subclass should implement the factory interface, so that setting the factory is simply a matter of assigning an instance of the listener. e.g. controller.setSynchronizationListenerFactory( new DifferentServerSynchronizationListener()); The default listener factory creates instances of JTATransactionListener.

PUBLIC: Return a new controller for use with a JTA 1.0 compliant TransactionManager.

Method Detail

isRolledBack_impl

public boolean isRolledBack_impl(java.lang.Object status)

INTERNAL: Return true if the transaction is rolled back.

Specified by:

isRolledBack_impl in class AbstractTransactionController

getTransactionManager

public javax.transaction.TransactionManager getTransactionManager()

PUBLIC: Return the transaction manager used to control the JTA transactions.

Returns:

The JTA TransactionManager that is used to obtain transaction state information and control the active transaction.

setTransactionManager

public void setTransactionManager(javax.transaction.TransactionManager mgr)

PUBLIC: Set the transaction manager used to control the JTA transactions.

Parameters:

mgr - A valid JTA TransactionManager that can be accessed by this controller to obtain transaction state information and control the active transaction.

getDefaultTransactionManager

public static javax.transaction.TransactionManager getDefaultTransactionManager()

setDefaultTransactionManager

public static void setDefaultTransactionManager(javax.transaction.TransactionManager defaultTransactionManager)

PUBLIC: Set the JTA transaction manager to be used. This can be called directly before login to configure JTA integration manually, or using Spring injection.
