The best way to protect your code is to never distribute it. Offer a web service or web application with servlets/JSP instead. Everything else is just about making reverse-engineering more difficult, but not impossible.

How big are the chances that anybody cares about your sources btw?

not worth the effort unless you've got a particularly innovative algorithm or something you want to protect. clue: most people haven't, even though they think they have

Hi,I would obfuscate the source code before I distribute it. This will sort of encode your source code and it is usually considered safe. Please google for 'obfuscation'. HTH

code obfuscation is like locking your garden shed up with 5 meaty padlocks. it'll only keep out the less-than-determined, only worth doing if you've got something really valuable to protect, and gives clues that you might well have something valuable to protect

and anyone who has doesn't have to come here and ask what has been asked a thousand times already.

He knows.

I've found that those virusses that take down powerstations and communications nexi work wonders.They prevent anyone from acquiring and using your software (or indeed their computers) so noone can get at your binaries to decompile them.

it costs money I guess. And as none of these products can give the 100% security the OP seems to think he requires for his supersecret brilliant code that everyone in the entire world will do anything to get their hands on, it can't be good enough...

and gcj is a piece of garbage with extremely poor compliance to the language standards.

Most Java code won't work with it if it uses something more complex than primitives.
