Hi guys,

I don't know if this topic belongs here but I am gonna explain my litte problem anyway. By mistake I deleted some part of Java code in my app. I tried to restore Windows to save the source file but it didn't work. I didn't get back the original source code no matter what I tried. But instead I got back the original class file so therefore I am wondering if there is a way of transforming this class file into Java source file, perhaps with the help of some other program or?

Pls help me out with this!

You are after a Java decompiler. Google for one and you should find what you need.

Hi again,

Don't bother! I found a resolution. At http://www.kpdus.com/jad.html
I found a program called jad.exe and with this I could decompile
class back into java source. Fortunately!

Cheers,

I never realised it was so easy to decompile a java file! I mean I know it's not perfect but doesn't this (jad) make non open source java programs a bit of a joke?

No. A good obfuscator can make reverse-engineering code more trouble than it's worth. Plus there's nothing that says all Java applications need to have class files on a machine the vendor doesn't control.
