MQSeries.net :: View topic - put between XAResource start and end not part of XA transctn

Hello,

I am trying to create a scenario using MQ 5.3 FP 12 for Windows.

The code below creates an XAResoure and QueueManger from an MQXAQueueManager. The problem is that the put to MyQueue commits immediately, despite the fact it is between the start() and end() methods. When prepare() is called, XA_RDONLY is returned, indicating that there is no MQ series work to commit. The message is already on the queue.

I'd be grateful if someone could tell me what I am doing wrong. The put needs to be prepared and committed at the end of the code sample. Thanks very much, in advance.

java.util.Properties properties = new Properties();
properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_BINDINGS);
properties.put(MQC.THREAD_AFFINITY, new Boolean(true));

MQXAQueueManager xaQMrg = new MQXAQueueManager("", properties);

MQXAResource xaRes = xaQMrg.getXAResource();

Xid xid = new MyXid(123456, "1234".getBytes(), "56787".getBytes());

qMgr = xaQMrg.getQueueManager();

xaRes.start(xid, XAResource.TMNOFLAGS);

MQMessage hello_world = new MQMessage();
hello_world.writeUTF("Hello World!");

int openOptions = MQC.MQOO_OUTPUT ;

MQQueue myQueue = qMgr.accessQueue("qlTestIn", openOptions,
null, null, null);

myQueue.put(hello_world);

xaRes.end(xid, XAResource.TMSUCCESS);
int prepareRc = xaRes.prepare(xid);
System.out.println ("Prepare returned " + prepareRc);

xaRes.rollback(xid);
qMgr.close();
