Java Forum / First Aid / April 2005J2ME, How to package/protect souce code?
Hi All, Thanks for help. I want to package/protect my source code for distribution, but user can easily decompress JAR file to java souce code. How can I protect it? Bes regards, Boki. Hi, There are many available tools to do what you want : Search for "java obfuscation" Regards, Arnaud > Hi All, > Thanks for help. [quoted text clipped - 5 lines] > Bes regards, > Boki.

Hi, Sorry, bit I've never really needed obfuscation, so I wouldn't be able to advise you on obfuscators. I remember of obfuscated code where methods and attributes names were replaced by reserved keywords (if, else, switch) ! This is perfect because no editor will let you edit such a code correctly, but I don't know which tool does this. Also, replacements by short names ( a, b, c ..) is good because it prevents from massive replacements by people decompiling the classes.

Obfuscation issues aside, have you thought about patents? If you have a patent/copyright on your source code, then decompiling the source will constitute a copyright infringement.
