A:

I have figured out the problem ..actually our client is using clustering of server with a load balancer.  after investigating each ends, I found  |The SOAP envelope does not  have proper structure as expexted by web service.  It is occuring when load balancer redirects request to a server.  It has been resolved when I reinstalled the SOAP web service EAR FILE on server.
