Error while Accessing WSEE Service

Hi ,
I am trying to call WSSE service using SOAPUI.

I have also specified the configurations for Outgoing WSS.
But I am Getting following error -

System.Web.Services.Protocols.SoapHeaderException: Server unavailable, please try later ---> System.UriFormatException: Invalid URI: The format of the URI could not be determined.    at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)    at Microsoft.Web.Services3.Security.Security.CanProcessHeader(XmlElement header, SoapContext context, String requestedActor)    at Microsoft.Web.Services3.Security.Security.CreateFrom(SoapEnvelope envelope, String localActor, String serviceActor) ]


Please let me know if any one knows the solution for it ...
