Java Proxy returning null object

Hello,

I prepared a java proxy scenario where in NWDS we are receiving response as required in standalone application; whereas in WS-Navigator we are getting empty structure with no values populated in response; the occurences of response structure is already set as 0..1.

Followed many links in SCN, still no clue.

Any idea, why we are getting the empty structure in response?

Regards,
