Web Service Issue

Hi,

I created a new custom web service and its working fine when tested through local Jdeveloper integrated weblogic server.

But the same web service, after deployment when tested through SOAP UI, it is giving below error (highlighted in bold):

What could be the cause of the issue...?...I am able to execute other BSSV objects through SOAP UI.
