What is the best Obfuscator to use with a Java Web Start application?

Do I have to rebuild every .jar when Obfuscating?

As our product is packaged over several .jar files some of which havent changed in a long time.

We dont want to redistribute every jar for each update

Thanks

Gary

I used the free ProGuard in the past and now the commercial Zelix Klassmaster. The latter provides flow obfuscation and string conversion, both which makes the code really hard to reverse engineer.

yguard is free and works quite well. It needs to be run on a jar file before it is signed
