Thanks for your quick reply. In most of quick start samples, there are two client programs: one is sendJMSMessage, one is sendESBMessage. Can you please let me know the justification on using these two, e.g. in which case the client should use sendJMSMessage, or sendESBMessage? I find there is sample jms_secured, wondering if I can use this to pass user credential instead of programming authentication in my action class (if it's sendESBMessage). Thanks for your help.
