Thanks for the response, i will go through these sites and check out . But i downloaded a tool called Excelsior JET which converts jar into and .exe so that i becomes decompilation as difficult as c/c++.
Any inputs on this tool will be welcomed.
Since it is nominated for the 2005 Java Developer's Journal Readers' Choice Awards, it can't be that bad.
>> so that i becomes decompilation as difficult as c/c++.

And only runs on Windows :-(

;-)

Oh, right, and of course there are no crackers who can crack the C/C++ wrapper and get to the JAR inside, right? ;)
Why not build your OWN obfuscator? that way, at least it'd be something new on the market that the crackers don't yet know how to break >;)

Is there any way of adding hash to the jar and so provide password for it. I have heard of this.

Not that I know of...

I don't know where you've heard of this, or what you've heard, but the ZIP support in Java does not include the ability to work with password-protected JAR/ZIP files.
