java-COM bridge

Hi

I want to call function in Microsoft COM object which is a com exe which resides in the system32 folder. I am able to call the function and I can send the parameters using Jacob or javin api but i am not getting response back from that function and it is returning only null. Using activex object in javascript it is working fine but my requirement is through java application i need to call. Can anybody suggest me how i can do it.
