How to check if a Internet enabled java program is the original one i made?

Question

I am writing a program which communicates with a server. But i want the server to only work with the original jar.

Is there anyway to do this? certificates etc?

This would be verifying the signature on the client side, not the server side. There's still no way of the server knowing if the client has been tampered with. – Tom Hawtin - tackline Jul 16 '14 at 06:23
@TomHawtin-tackline it depends on a particular task. In some cases checking on the client side is enough. In some cases (for online games, to prevent cheating with patched clients) it is not. – Jul 16 '14 at 06:25
Im using the client to send back data to the server but the data Needs to be legit. Havent Been able to try testing the cert yet because my java Broke.... – Oisin100 Jul 16 '14 at 18:19
