I'm not a Java developer, but I'd like to know if my idea is possible.

I have a java application, (I didn't make it), which runs on Linux and windows, using a JVM. I beleive it is written using JDK 1.5. Would it be possible to run this on a Samsung Galaxy Tab running Andriod 2.2 in some shape or form. Preferably without touching the existing code.

In it's normal enviroment, on a linux box it mounts a drive to a windows machine and executes a jar file. On a windows machine it maps a drive to a windows machine and runs the jar file.

My apologies if this all sounds like rubbish, but I mentioned I'm not a Java developer. Could I get this running? Where should I start / who should I speak to?
