java.lang.Throwable	getRollbackCause() Returns the Throwable that caused the current transaction to be marked for rollback, provided that any exists.
java.lang.Object	getTransactionKey() Returns a transaction key that can be used to associate transactions and Brokers.

Method Detail

getTransactionManager

javax.transaction.TransactionManager getTransactionManager()
                                                           throws java.lang.Exception

Return the TransactionManager for the managed runtime. This manager is used to register synchronization listeners, to map transactional PersistenceManagers to the current transaction, and possibly to enlist XA resources.

Throws:

java.lang.Exception

setRollbackOnly

void setRollbackOnly(java.lang.Throwable cause)
                     throws java.lang.Exception

Sets the rollback only flag on the current transaction. If the TransactionManager is capable of tracking the cause of the rollback-only flag, it will also pass along cause information.

Parameters:

cause - the Throwable that caused the transaction to be marked for rollback, or null of none is known

Throws:

java.lang.Exception

getRollbackCause

java.lang.Throwable getRollbackCause()
                                     throws java.lang.Exception

Returns the Throwable that caused the current transaction to be marked for rollback, provided that any exists.

Returns:

the Throwable cause, or null if none

Throws:

java.lang.Exception

getTransactionKey

java.lang.Object getTransactionKey()
                                   throws java.lang.Exception,
                                          javax.transaction.SystemException

Returns a transaction key that can be used to associate transactions and Brokers.

Returns:

the transaction key

Throws:

java.lang.Exception

javax.transaction.SystemException

doNonTransactionalWork

void doNonTransactionalWork(java.lang.Runnable runnable)
                            throws javax.transaction.NotSupportedException

Do a unit of work which will execute outside of the current managed transaction.

If the runnable object encounters an exception it should be wrapped in a RuntimeException and thrown back to the caller

Parameters:

runnable - The runnable wrapper for the work that will be done. The runnable object should be fully initialized with any state needed to execute.

Throws:

javax.transaction.NotSupportedException - if the transaction can not be suspended.
