Problems calling web service from 64-bit client

[Meira]

I have a web service (.NET 2.0) that defines a function with input parameters defined as "int".
This web service is running on a 32-bit machine or 64-bit machine.
There is a client that is calling this web service method (written in js).
Client that running on a 64-bit machine failes.
while client that running on a 32-bit machine succeed the request.
Is the any idea for the reason?

I think you are going to have to specify which version of int to use because the bits that represent the integer are going to be different on a 32 bit operating system vs a 64 bit operating system.

If you are targeting both 64 and 32 bit platforms, consider using Int32 instead of "int".
