I have a need to update Queues belonging to 2 different Queue Managers. Is it possible to have the backout/commit under the control of 1 of these?

I have tried the following with No success:

QM1 = new MQQueueManager( QM1NAME, MQC.MQCNO_STANDARD_BINDING );
QM2 = new MQQueueManager( QM2NAME, MQC.MQCNO_STANDARD_BINDING );
Q1 = QM1.accessQueue(Q1NAME, openOptions, null, null, null);
Q2 = QM2.accessQueue(Q2NAME, openOptions, null, null, null);
QM2.begin();
MQMessage message1 = new MQMessage();
message1.userId = "ADMIN";
message1.writeString("BOGUS MESSAGE1");
MQPutMessageOptions pmo1 = new MQPutMessageOptions( );
pmo1.options = MQC.MQPMO_SET_IDENTITY_CONTEXT | MQC.MQPMO_SYNCPOINT ;
Q1.put(message1, pmo1);
System.out.println("A message has been successfully written to Queue '"
+ Q1.name );

MQMessage message2 = new MQMessage();
message2.userId = "ADMIN";
message2.writeString("BOGUS MESSAGE2");
MQPutMessageOptions pmo2 = new MQPutMessageOptions( );
pmo2.options = MQC.MQPMO_SET_IDENTITY_CONTEXT | MQC.MQPMO_SYNCPOINT ;
Q2.put(message2, pmo2);
System.out.println("A message was successfully written to Queue '" +
Q2.name + "'. Do you wish to commit BOTH messages? (Y/N)" );
ans = ReadString(1);
System.out.println("Your answer was '" + ans + "'");
if ( ! ans.toUpperCase().equals("Y") )
{
QM2.backout();
System.out.println("The messages have been backed out");
}
else
System.out.println("The messages remain in the Queue");

The message is removed from QM2 queue, but not the QM1 queue. What I really need is to be able to control all of these backouts from a single resource manager. It seems like this may not be possible.

Can anyone help me with this.

Thanks
