Hi Sivakumar -

Thanks for the reply.

I do know about using the URL approach to avoid using the factory - but was a bit leary on using this in a clustered environment in the future, as well as was hoping I could access it via JNDI or at the very least - have the lib live where bundles can have access to them and not be included in the bundle itself.

Thanks again!

Hi Robert

I think the imqjmx.jar needs to be in the classpath [1] only to obtain
the JMX Connector through the convenience AdminConnectorFactory. There
is another method to obtain a JMX connector using standard JMX classes
instead, described in [2]. Would that help?

Thanks
