wires label not visible on Websphere portal server

Hi,

I developed two JSR 168 cooperative portlets. I made wsdl files for each and made changes in the jsp's and classes so as to communicate a test string value.

I tried to keep these two portlets on two different pages and tried to wire them, But i am not able to see 'wires' tab on the 'Edit layout' of the Websphere portal server.

did i miss anything? Please let me know..,

FYI..,

I am using RAD 6.0 and Portal test server 5.0 version.
Please help me out in accessing the 'wires' tab. I am not even able to see the 'wire' tab in 'Edit page layout' screen. the two portlets are havinga Edit access as well cofigured WSDL files with output and input params.
