You can't, but you can make things more difficult for the reverse engineers, with obfuscation. This has been discussed previously in this forum, so just search this forum for "obfuscation" or "obfuscate" and should find some information. You could also search on Google for "java obfuscation." Finally, you can check out JavaCC (http://www.webgain.com/products/java_cc/) which comes with an obfuscator as a demo of the parser generator.

You can simply add build targets
that use Jode to create obfuscated JAR files in a different delivery directory
But If your only target platform is Windows, you may native compile your app - optimized Pentium code is much less comprehensible than Java bytecode (even if obfuscated). Still, an experienced person shall be
able to reverse engineer your app but that would take him/her much,much more time.

So, if you are planning on selling a very expensive product, I don't know what to advise you, because with lots of effort your program can be de-compiled and reused that way.
