Creating a jar file with map reduce program on windows and then running it on linux (hadoop)

Question

i'm usually using windows, but for hadoop im using ubuntu (in oracle VM) i was wondering wherever its possible to create in netbeans a jar, that contains compiled mapper/reducer/java program that executes it, on windows environment and then launch that jar on Linux environment?

I know this is probably a beginners question, but i just didn't mange to find stuff on this issue on the web

thanks in advance!

Yes, Java bytecode is platform-independent. Java classes compiled on Windows can run on Linux. You don't have to do anything special; just build the jar, copy it into your Linux VM, and run it.
