Error while creating a webservice model

Hi All,

I am doing the EMail WebService exercise. While creating the webservice model I select the UDDI or URL Radio button and in the wsdl field I paste the following url : http://www.abysal.com/soap/AbysalEmail.wsdl .

When I click next in the proxy definition screen, I get the message Invalid WSDL or WSDL not found and the Finish button is not highlighted.

I checked the webservice mentioned above it is fine and working. I cannot understand why this is not accepted in NWDS

Pls Reply ASAP
