Calling ABAP RFC via JCO

Hi,

I have created an ABAP function and RFC enabled it but when I am calling it using JCO, I am not getting any values. I have tested the function using Transaction SE37 and the return value is comming correctly.

Is there any thing that I am missing? I am able to call other RFC functions using the same JCO code piece.

Any help is appreciated.

Thanks
