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

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

delistResource

public boolean delistResource(javax.transaction.xa.XAResource xaRes,
                              int flag)
                       throws java.lang.IllegalStateException,
                              javax.transaction.SystemException

flag - One of the values of TMSUCCESS, TMSUSPEND, or TMFAIL

Throws:

java.lang.IllegalStateException - Thrown if the transaction in the target object is inactive.

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

public boolean enlistResource(javax.transaction.xa.XAResource xaRes)
                       throws javax.transaction.RollbackException,
                              java.lang.IllegalStateException,

xaRes - The XAResource object representing the resource to delist

Returns:

true if the resource was enlisted successfully; otherwise false.

Throws:

javax.transaction.RollbackException - Thrown to indicate that the transaction has been marked for rollback only.
