Hi ratndeep,
I'm not familiar with SOAPEXTENSION you're mentioning so I cannot tell what kind of problems it might cause.
Have you looked at usual symptoms of wrong behavior outside soapUI:
- Are you receiving responses inside soapUI when SOAPEXTENSION is not used?
- Are you sure that responses are being returned? You can check this by using some of the network traffic monitoring tools like Apache TCPMon (that soapUI directly supports once you install TCPMon and configure soapUI to use it) or a more advanced tool like Wireshark.
Cheers!
