Installing Jadclipse in Eclipse
Today I am going to show you how to install and use Jadclipse. Jadclipse is eclipse plug-in that integrates Jad (Java decompiler) with Eclipse.
- First you require Jad for decompiling java files. You can find a list of mirrors on this site where you can get JAD for various platforms. Download it and unzip into any folder on your hard drive.
- Next download the Jadclipse plug-in jar file from here and place the jar file in your eclipse plugins folder
- Restart your eclipse. If eclipse didn’t recognize the plug-in then launch eclipse with -clean flag.
eclipse -clean
- Configure the path to the Jad executable in eclipse under Window > Preferences… > Java > JadClipse > Path to Decompiler.
- Set the full path of the jad executable, e.g. C:\Program Files\Jad\jad.exe
- Go to Window > Preferences… > General > Editors > File Associations and make sure that the JadClipse Class File Viewer has the default file association for *.class files.

file association
Now everything is done. If you want to view the source for any class then simply ctrl+click on that class then the source for that class will be showed in your eclipse editor.












How can I get eclipse to allow me to open the class files? The file association is correct, but it doesn’t work. I have a jar to decompile, what should I do with it?
First you should attach your jar to the projects build path. Then from any java file if you are accessing any class from the jar file then simply ctrl+click on the class name. If the source is attached to the jar eclipse will open the source java file, otherwise JAD will decompile the class file and it will be opened in the editor window.
