Google Answers: Protect/encrypt java class (jar) files from theft: "Obfuscator can not help protect your Java code from decompilers. Obfuscator can hide valuable names but not hide your logic or algorithms. There are a number of Java de-compiler products on the market that do this task such as Mocha, DJ Java Decompiler, Jad, WingDis, DejaVu, open source decompiler Jreverse Pro, Cavaj Java Decompiler, JCavaj Java Decompiler, Decafe Pro, SourceAgain ... etc. They produce readable source code even though your classes have been obfuscated. http://www.excelsior-usa.com/jetprotection.html Excelsior JET JVM offers a solution but actually it recompile your java source code and that is not Java program anymore. The only solution is to create a java secure class loader which does encrypting/ decrypting classes in the memory. We got the solution and is preparing patent it. The secure class loader already apply to SETECS products written in JAVA. It is proven as secure and efficient solution so far."
