Decompiling Java. (Need Advice)

[BadStrafe]

Okay, So I ran into a little problem the other day, and I've been racking my brain for the past few hours trying to find a work around.
Im trying to decompile the java from a game so I could toy around with some of the classes, and maybe start work on some custom DLL's. However.. I've never worked with a java based game before, and figured i'd come get some advice from anybody here who could assist.

The game itself runs in java, however it seems to be wrapped in an exe file, which naturally is throwing off every java mem editor I throw at it.


If anybody could throw me a bone, and point me in the right direction. Id greatly appreciate it.

It should probably also be noted that I dont have a very vast knowledge of writing hacks, or exploits.. But i am an experienced bot maker, with a basic understanding of C#.
So laymen terms are what Im lookin for, ti'll i get myself some more experience.

Open the exe with 7zip.
And if you find a way to run multiple clients, tell me!

Running the game multiple times requries some AHOLE garbage, ive been working on it about 2 weeks and ive decompiled and come close, basically the game checks for process id and HWD id so you have to make a launcher that runs the program and masks the exe name as something else and changes your external ip through a vpn you create and then you further need to block the HWD id check, ive gotten 2 to run but any more than that the java lags out and explodes from too many checks on the pc at 1 time =P and i have a good computer so that means GGWP for people trying to do 3-more clients
