Java DeObfuscator description
JDO contains a simple and easy to use GUI that makes automatic deobfuscation a very easy job Java DeObfuscator is a small application that will make decompilation easier. It works on class files directly. JDO contains a simple and easy to use GUI that makes automatic deobfuscation of Java projects a one-click operation!

Load *all* of the class files from the project into JDO. You can do this by clicking the ... button and selecting multiple files in the open box (sorry you cannot choose a directory, or a .jar file yet!).

Once they are all loaded in, you can browse through their methods and fields. Any that are highlighted in red are to be automatically renamed (you cannot turn this off yet).

Click Deobfuscate and the files will automatically be deobfuscated and saved into their new class file names. If any of the class file names did not change then it *will* overwrite the originals!

Leave the JDO window open, and run jad or your favourite decompiler over the newly created .class files.

While browsing the new decompilations, you might think of better names from some of the methods or class variables (or the classes themselves). If so simply find the offending item in the JDO window, right click it and change its name. When you think youve done enough, click Deobfuscate again and re-decompile. You should be able to repeat this step as many times as you like!

In the end you should have a much better decompilation!
