I have downloaded Java decompiler jd-eclipse-2.0.0.zip and followed the steps to install it in eclipse.
I want to open a jar executable file in eclipse to see its source code but I don't know how to open it.
My question is: how can I open it in eclipse to see its source code?
Unzip the .jar file. (A jar file is really a zip file), and then open the .class files in eclipse.
