message proority in JMS MQ

I am using JMS with MQ. If i set message priority in sender program, messages are not storing in priority order in MQ Queue. stores as FIFO. When i executed JMS with Weblogic, in weblogic, i set priorities for Q (sort by, priority,..). it works fine in weblogic.

I think the same has to be done in MQ Queue level also.

Here is the sample code for JMS MQ.

mqFactory = new MQQueueConnectionFactory();
if( aQueueMagager== null) {aQueueMagager = new String();}
if( aPort== null) { aPort= new String("1414");}
if( mqChannel == null) { mqChannel = new String(this.CHANNEL);}
if( aServer == null) {aServer = new String("localhost");}

queueConnection = mqFactory.createQueueConnection();
System.out.println("After queueConnection");
Queue tmp_queue = this.getQueueSession().createQueue("SCE3JMS");
qsender = this.getQueueSession().createSender(tmp_queue);
msg = this.getQueueSession().createTextMessage();
queueConnection .start();

msg.setText(new String("test :"+prio));


anybody tell me how to set MQ Queue msg priorites as message specific.

A JMS provider tries to deliver higher-priority messages before lower-priority ones but does not have to deliver messages in exact order of priority.
