Hi,
If i use INITIAL_CONTEXT_FACTORY=com.ibm.mq.jms.MQQueueConnectionFactory
PROVIDER_URL=tcp://localhost:1414/SYSTEM.DEF.SVRCONN in JMSAdmin.config (&run JMSADMIN -v xxxx)
I am getting following error.
Error: javax.naming.NoInitialContextException: Cannot instantiate class: com.ibm
.mq.jms.MQQueueConnectionFactory [Root exception is java.lang.ClassCastException: com.ibm.mq.jms.MQQueueConnectionFactory]
If i use INITIAL_CONTEXT_FACTORY=com.ibm.mq.jms.context.WMQInitialContextFactory
PROVIDER_URL=tcp://localhost:1414/SYSTEM.DEF.SVRCONN
Then it works. Let me know if we can create JNDI for MQQueueConnection Factory in MQ series or not.
Thanks in advance
Adi |

I always use
com.sun.jndi.fscontext.RefFSContextFactory
as initial context factory for JNDI creation...
wandering if we can use any connection factory in place on initial context or not....

If I understand you correctly... and I might not 
You are saying that if you set your initial context factory to something which isn't an inital context factory then you get a class cast exception? I am not sure why you are surprised what are you expecting to work here?
JMSAdmin uses an initial context factory to connect to before then allowing you to create appropriate connection factories and destinations. This is fundamental JMS / JNDI setup. I would suggest you read up more on JMS messaging / code patterns.
If I have miss-understood what you are trying to achieve, please clarify. |

Ok, to be more clear. I am using MQQueueConnectionFactory in axis2.xml like
<parameter name="java.naming.factory.initial">com.ibm.mq.jms.MQQueueConnectionFactory</parameter>
Where JNDIName will refer to QueueConnectionFactory created in MQ. I created QCF using .... +
INITIAL_CONTEXT_FACTORY=com.ibm.mq.jms.context.WMQInitialContextFactory
I am facing few prblems in accessing this Queue using this QCF. So i thought we need to create connection factory related to MQQueueConnec... so declared some thing like this in JMSAdmin.
INITIAL_CONTEXT_FACTORY=com.ibm.mq.jms.MQQueueConnectionFactory
It seems we do not have any factory support like this. Correct me if i am wrong?
Secondly, if not exists can i use QCF created on WMQInitialContextFactory in axis2.xml where i am referring to xxxxxMQQueueConnectionFactory?
Ofcourse i can use "<parameter name="java.naming.factory.initial">com.ibm.mq.jms.context.WMQInitialContextFactory</parameter>" in axis2.xml, where i have some other issues & no sol yet (http://www.nabble.com/Axis2-with-JMS-Transport-td17485892.html) , so digging for options  |

erm,
I don't know anything about axis...
But as I said before, you need to lookup and understand how the JNDI / Administered object messaging patterns work for JMS.
You cannot use MQQueueConnectionFactory in the xml as you suggest because it is not an initial context factory, it cannot be used as an initial context factory, it just doesn't implement the correct interface.
MQQueueConnectionFactory is used as a connection factory in JMS to create a connection to MQ, and can be stored inside some form of JNDI.
WMQInitialContextFactory provides a lookup mechanism based on an MQ back end to allow you to look up objects (such as MQQueueConnectionFactory objects). |

WMQInitialContextFactory requires a fix pack and is not a good fit as it is not static...
The file context comes with the product and is a better fit.
Enjoy

I am using the initial context factory as "com.sun.jndi.fscontext.RefFSContextFactory" but still I am getting the
jmeter.protocol.jms.sampler.JMSSampler: Cannot instantiate class: com.sun.jndi.fscontext.RefFSContextFactory javax.naming.NoInitialContextException: Cannot instantiate class: com.sun.jndi.fscontext.RefFSContextFactory [Root exception is java.lang.ClassNotFoundException: com.sun.jndi.fscontext.RefFSContextFactory ].
I am working on Jmeter. I need to do some performance testing and I am using Hermes JMS as the MQ. So I am trying to set up the response and request queue and send the message.
I am using the Queue Connection Factory as "com.ibm.mq.jms.MQQueueConnectionFactory" |

Something is wrong with your classpath. The relevant jar might be missing from your classpath. If using a 3rd party product like Hermes or such, make sure all the relevant jars have been defined to the product / classpath.
Have fun
