jar files from mac to pc

[willemjav]

I might be a hopeless programmer?

wrote a small application memorycards for kids (images music etc.)
compiled from MAC through netbeans. The program works fine on mac by just 2xclicking on the jar. But on a pc of a friend he gets the following message


Notice that tries to find a file jar.clas on the path D:\MemoryCards\.
