How to decompile a whole Jar file?

I have a .jar file. Its a single file, but I want to "decompile" it to get at the original java code (or at whatever would be closest to the Java code - something I could understand, and edit). I believe my file is (specifically) a java applet, but its saved as an executable jar file (.jar).

How would I do such a thing?

Answer 1

Take a look at Java Decompiler.

It allows you to decompile jar files with the JD-GUI and browse the class files as source.
