Could some one help me on the below issue.

I am trying to cretae a XML request using AXIS2 frame work. Request should be generated with signature information. I have created request successfully, but while getting response I have recieved *********************** RampartReceiver received . I got response as well.
after that I am getting exception like below. In the response securti is not required. This is plain response which I am getting. But the request should be with teh securty. It is serching for wsse security in the response as well. How can I remove this security while getting in the response.

Please help me on this. It is bit urgent. Please let me know if you required any more details.
