Hi all
We have WAS6.1 and MQ6.0 running on the Sun v10. Portal application is using the JMS to put the java object in the remote def queue.
we have QConnfactories configured on WAS. we have the problem to send the request object in to the queues. When portal application session timed out then the request message is delivering to the destination queues. The message is sitting in to the transmission queue during session time. once session timed out the oppros() count is one. then the message is releasing from the transmission queue.
What is problem what we are really missing how to sol this problem
Could you guys plz help me. Its urgent. 
Thanks

You are putting the message in a transaction.
You are not committing the transaction, until the session times out.
You need to commit the transaction.

To be a little bit clearer:
The request message cannot participate in the global request transaction.
The request message will not be sent until it is committed.
So if you have a request / reply model the request message if transacted needs a transaction of its own independent of the global request transaction and that gets committed before the global request transaction is committed.
Should you so care the reply can be part of the global transaction... but I would not encourage it: If for whatever reason you roll back the global transaction is there a reason to roll back the reply as well??
Enjoy

Is there any thing i am missing in the following code.
public String putMessageOnQueue(String queueName, HashMap msg)
throws MessagingException
{
try
{
// Look Up the Queue
Queue queue = (Queue)ctx.lookup(queueName);
if (logger.isDebugEnabled())
logger.debug("Out Queue Found: " + queueName);
//Send the message request
ObjectMessage omsg = null;
if (qs !=null)
{
// Uses Queue Sender
logger.info("Writing with QSESS");
QueueSender qSender = qs.createSender(queue);
omsg = qs.createObjectMessage(msg);
qSender.send(omsg);
qSender.close();
qSender = null;
queue = null;
// TODO - logic added as fix to queue problem
logger.info("Closing Queue Session");
close();
logger.info("Re-Open Queue Session");
// Re-open Connections so it can be used later
connectQCFMgr();
logger.debug("Conn created");
logger.info("Re-opened Queue Session & Connection");
}
// Get the message ID
String msgid = omsg.getJMSMessageID();
logger.info("Message Sent, ID:- " + msgid);
return msgid;
}
catch (NamingException nex)
{
logger.error(nex);
throw new MessagingException(nex);
}
catch (JMSException jmex)
{
logger.error(jmex);
if (jmex.getLinkedException() != null)
logger.error("JMS Detailed Exception:- " + jmex.getLinkedException());
throw new MessagingException(jmex);
}
}
public void close()
throws MessagingException
{
logger.debug("Closing queue objects");
try
{
if (qs != null)
qs.close();
if (qconn != null)
qconn.close();
if (sess != null)
sess.close();
if (conn != null)
conn.close();
if (ctx != null)
ctx.close();
}
catch (JMSException jmex)
{
logger.error(jmex);
if (jmex.getLinkedException() != null)
logger.error("JMS Detailed Exception:- " + jmex.getLinkedException());
throw new MessagingException(jmex);
}
catch (NamingException nex)
{
logger.error(nex);
throw new MessagingException(nex);
}
//Start Session - Without Commit
qs = qconn.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
//Start Session - With Commit
qs = qconn.createQueueSession(true, Session.AUTO_ACKNOWLEDGE);
// Commit
logger.info("Msg Sent - Commiting Session");
if (qs.getTransacted())
{
qs.commit();
logger.debug("Commit completed");
}
else
{
logger.warn("Commit not allowed");

There is no statement to add.
Try setting transaction not supported on the method of your EJB that sends the message.
If you must you could just as well set requires new transaction... However you might need to find a way to commit as I don't know where the automatic commit would find place...
Enjoy
