Provider Webservice not getting invoked from weblogic server

Hi Experts,

I have created a provider webservice in development environment and tested it using SOAP UI and also from Apache weblogic server and it was running fine.

When I have deployed this Provider webservice along with its code in QA environment, this webservice is not getting hit by weblogic server.

Weblogic server is pointing to correct QA Provider webservice URL and during webservice invoke they are not getting any error or exception.
NO response is returned.

Also, in Wm this webservice is not getting hit.
I have kept all ACL to anonymous.

I am not sure, but is it that we need to re-create webservice descriptor manually instead of deploying?

Please help. I am stuck with issue.
