thanks a lot for pointing out this. Our web developers are using Websphere, it looks like WAS uses its own JNDI repository. I checked with JMSAdmin, there is not even such queues defined for the application.
In between, I wrote a few MQJMS test programs and setup Q, and QCF in the jndi name space. they all work fine without any channel and port involved.
many thanks for all the helping tips from everyone.

Hi Paul,
Check your JNDI values with the JSMAdmin tool. You probably set your QCF with the following command:
define qcf(qcfClient) qmgr(MY.QMGR) channel(SYSTEM.DEF.SVRCONN) hostname (MYHOSTNAME) port(1414) transport(CLIENT)
Hence, you needing to increase the max channel attribute even though it is local. Try the following:
define qcf(qcfClient) qmgr(MY.QMGR) transport(BIND)
This will not use any channels and should be faster.
Hope that helps.
