need a .jar edit

I have been using a java app for a while that a friend made for me, however it was linked to his webhost so he could make sure no one else could use it other than myself as requested by me just in case anything should happen.

However he passed away a few months ago:( & now his webhost as expired & i was looking for help before this happened without such luck. Anyways now the server is no longer about it no longer works. So im needing for someone who could edit the .jar file by decompiling it & removing the server control parts & recompile it.

I have no idea what to do myself as ive no time or ability to learn java coding & would really like some help here.

thanks:mad :o

Edit.. i found a decompiler n im not sure if it worked fully but someone told me on irc #java chat that i need to change the right ifeq to an ifne in the byte code, however i no idea what that means.

thanks
