Title: Multiplatform...
Post by: jeremejazz on February 18, 2010, 04:56 AM

hi, I am programming in JAVA in windows, I haven't tried it on other OS. Will the object files (.class, .jar) produced in windows run on Linux and other operating systems that support Java? I was thinking that you would have to compile the source code there again.

If you stick to core java (ie., no JNI, and be careful about stuff like launching external processes), don't depend on OS-specific file locations, et cetera... then your .jar files will execute on other platforms without recompiling.

As you develop you should test your programs on another OS, say Linux in a VM for simplicity. Ideally you would test on all target platforms but even just testing on two separate OS will help you get a good idea what's portable and what's not.
