Hi!
Sorry, just as I foretold, I forgot

. Attached you will find the jar file of my software, run it like this:
java -jar javaMet.jar
it will display the contents of a server.met, known.met or part.met file. It will not let you modify anything, just show.
Hope it helps. If you have any difficult time with it, please PM me, since this software is pretty offtopic here.
Regards.
Edit: I had to change the extension of the file to .zip, just change it back to .jar and use it as I explained to you.
