First user discovery in java application

Question

I want my java desktop application to find out if it runs it for the first time on this computer. Since the jar file can be shared between users, I do not want to write to the file inside the jar file. Obviously, there are many ways to do this, but what do you recommend? (It must be cross-platform). thank
