Below, you can see it in my 'externalized' plugins directory. If JadClipse is installed correctly, in Window → Preferences, you should now have a Java → JadClipse entry. If you added your jad directory to your system path as shown above, your 'Path to compiler' entry should be fine.
If you didn't, you'll need to modify the path to JAD so that JadClipse can find it. I modified my temporary files directory from the default to go to C: temp.jadclipse, but this is not necessary. In Window → Preferences, you should check your General → Editors → File Associations to be sure that the JadClipse Class File Viewer is set as the editor for your *.class files. Let's try JadClipse out. As an example, I downloaded the Jakarta Commons Lang library from.
