Writing a message to the work header

Messages sent to WebSphere MQ for z/OS, which are destined for a queue managed by the z/OS Workload Manager, require a special header. The work header is prefixed to regular message data.

ImqQueueManager mgr ;             // The queue manager.
ImqQueue queueIn ;                // Incoming message queue.
ImqQueue queueWLM ;               // WLM managed queue.
ImqMessage msg ;                  // Incoming and outgoing message.
ImqWorkHeader header ;            // Work header information
 
// Retrieve the message to be forwarded.
queueIn.setConnectionReference( mgr );
queueIn.setName( MY_QUEUE );
queueIn.get( msg );
 
// Insert the Work header information.  This will vary
// the encoding, character set and format of the message.
// Message data is moved along, past the header.
msg.writeItem( header );
 
// Send the message to the WLM managed queue.
queueWLM.setConnectionReference( mgr );
queueWLM.setName( /* ? */ );
queueWLM.put( msg );
