I have a Webservice running on Websphere Application server.
I know the URL for the webservice.
I want to call this webservice from a portlet which is on Websphere
portal server.
Is there any link on this?
I tried creating the Client from the wsdl for my portal project but in
a way i am getting a null pointer exception when i invoke the web
service from my portlet..

Any help would be appreciated..
