Implementing CallBacks in Weblogic 7.0

Question

I have a WebService with a JMSControl subscribing to messages from a Topic and
invokes a callback upon receipt of the message. My webservice client is a rich
GUI Client running under Java WebStart. I need a way to specify the Callback address
on my request so that the client receives a notification for every message published
on the Topic, how do i do that. I get this exception now.
"Service tried to perform a callback (onMessage()), but no callback port was specified
in the original request. If you are calling this service from .NET, make sure
you call set callbackLocation() on the proxy prior to making the request."

Navin,
I guess you are using 'WebLogic Workshop' for developing your WebService.
Could you please post all Workshop queries in the
'weblogic.developer.interest.workshop' newsgroup.
As for the current problem, you can call the method
setCallbackLocation(String url) on the JwsContext object to set the callback
location.
Regards,
Anurag
