Support for signature using secretkey

Hi,

i want to integrate my OWSM wss11_message protection policy with soap ui . it is possible ?
steps i have already done :

1) created a proxy service and used wss11_message protection policy at server side.
2) configured the keystore(with alias server_pvt_key) in credential store.
3) now if i try to hit the service from sbconsole(ans substitue server_pvt_key as the encryption key) it works fine both input and output are encrypted.
4)i am hitting the same servce from soap ui but getting the following
<faultcode>soapenv:Server</faultcode>
<faultstring>BEA-386200: General web service security error</faultstring>
<detail>
<con:fault xmlns:con="http://www.bea.com/wli/sb/context">
<con:errorCode>BEA-386200</con:errorCode>
<con:reason>General web service security error</con:reason>
<con:location>
<con:path>request-pipeline</con:path>
</con:location>
</con:fault>

i have imported the client keystore into the soap and configured ws-incoming and ws-outgoing configurations.

my question how i can configure wss11 client policy into my soap ui.

thanks
