Executable jar does not execute !!

Dear all,

i am having a bunch of classes i create a jar out of them

now

when i attempt to run this jar in another machine i found the following prblames

1. i get the error related to "mian does not exist"

2. in another machine it ask me extract the jar file (i think coz win rar is installed)

while in fact that jar file cotains a main class and i want to execute that jar file when ever some one click on that.

So any one please guide to achieve the solution of my problame.

thanking you

ishan
