Failed to Load URL

Hi,

When I am trying to consume my WCF Services from SoapUI I am getting this below error.
Error loading WSDL
Error loading [http://ServerName/Services.svc]: java.lang.Exception: Failed to load url; 0
I used SoapUI before for the same and it has been working for me. I got the same error with SoapUI 4.1 and i looked on forums and i found out that it is fixed in new version/nightly build. So i downloaded the new version but still getting the same error.

Here is the SoapUI Error log.

Does it have anything to do with my Local Java version or Service. I am hosting this services in IIS. When i try to access this services from Browser and or my Visual Studio test client everything works fine.
But i want to make this work with SOAP so i can have my client using this services via SOAP as well.
Please help.

Thanks,
Vivek
