recreate

public void recreate(Xid xid,
                     long timeout)

Description copied from interface: TransactionImport

Recreate a transaction based on the Xid. This call causes the calling thread to be associated with the specified transaction.

This method imports a transactional context controlled by an external transaction manager.

Specified by:

recreate in interface TransactionImport

Parameters:

xid - the Xid object representing a transaction.

release

public void release(Xid xid)

Description copied from interface: TransactionImport

Release a transaction. This call causes the calling thread to be dissociated from the specified transaction.

This call releases transactional context imported by recreate method.

Specified by:

release in interface TransactionImport

Parameters:

xid - the Xid object representing a transaction.

getXATerminator

public javax.resource.spi.XATerminator getXATerminator()

Description copied from interface: TransactionImport

Provides a handle to a XATerminator instance.

The XATerminator exports 2PC protocol control to an external root transaction coordinator.

Specified by:

getXATerminator in interface TransactionImport

Returns:

a XATerminator instance.

preInvokeTx

public void preInvokeTx(boolean checkServletInvocation)

PreInvoke Transaction configuration for Servlet Container. BaseContainer.preInvokeTx() handles all this for CMT EJB. Compensate that JavaEEInstanceListener.handleBeforeEvent( BEFORE_SERVICE_EVENT) gets called before WSIT WSTX Service pipe associates a JTA txn with incoming thread. Precondition: assumes JTA transaction already associated with current thread.

postInvokeTx

public void postInvokeTx(boolean suspend,
                         boolean checkServletInvocation)

PostInvoke Transaction configuration for Servlet Container. BaseContainer.preInvokeTx() handles all this for CMT EJB. Precondition: assumed called prior to current transcation being suspended or released.

Parameters:

suspend - indicate whether the delisting is due to suspension or transaction completion(commmit/rollback)

getTransactionRemainingTimeout

public int getTransactionRemainingTimeout()
                                   throws SystemException

Return duration before current transaction would timeout.

Specified by:

getTransactionRemainingTimeout in interface TransactionImport

Returns:

Returns the duration in seconds before current transaction would timeout. Returns zero if transaction has no timeout set and returns negative value if transaction already timed out.

Throws:

IllegalStateException - Thrown if the current thread is not associated with a transaction.

SystemException - Thrown if the transaction manager encounters an unexpected error condition.

registerRecoveryResourceHandler

public void registerRecoveryResourceHandler(XAResource xaResource)

Allows an arbitrary XAResource to register for recovery

Specified by:

registerRecoveryResourceHandler in interface TransactionImport

Parameters:

xaResource - XAResource to register for recovery
