Hi Daniel
Thanks for your reply !
I am using JSR 268 portlets,.I Configured below WSDL URL in  my portal connections, While creating WSRP producer, and i have not checked the "Use Proxy for Contacting Producer", rest all i have not modified.
     http://localhost:7101/portletProdApp/portlets/wsrp2?WSDL
Here is my Connections.xml that is generated.
I am new to this portlets, Could you please let me know how can check for proxy restrictions ?
