[Mrpostman-developers] Installing .jar file for Ubuntu Linux

[Michael H. <iti...@ho...>]

I've been trying to get MrPostman running on Ubuntu 5.10 for a few weeks.  
My understanding is that JAVA is a cross-platform language and this 
shouldn't be as difficult as it is proving to be.

There seems to be some question as to whether or not the version of JAVA 
installed is the same one that MrPostman is written in, and I have a hunch 
that this may be the problem.  Ubuntu comes with a GNU-licensed version, 
while I think MrPostman might be written for SunJava.  For the good of this 
project I hope that I'm wrong - It would be sad to learn that this super 
project is written in proprietary code!

Can anyone confirm whether this is a valid version of JAVA to run MrPostman?

Thanks,
Mike
