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.

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.

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.
