How to use JadClipse?

[Warren Tang]

Hello,

I am learning Java, and in particular inner classes now. I want to see
the code the compiler generates other than what I write. For example, I
want to see the following code(TimePrinter is an inner class, whose
outer class is TalkingClock):

warren.tang.TalkingClock$TimePrinter
{
warren.tang.TalkingClock$TimePrinter(warren.tang.TalkingClock)

public void
warren.tang.TalkingClock$TimePrinter.actionPerformed(java.awt.event.ActionEvent)

final warren.tang.TalkingClock
warren.tang.TalkingClock$TimePrinter.this$0
}

(So I am just finding something that is similar to the Reflector tool in
..NET.)

Then I found JadClipse which is an decompiler plugin for Eclipse. I've
just installed JadClipse configured it per the instructions here:
http://jadclipse.sourceforge.net/wiki/index.php/Main_Page

However I don't know how to use JadClipse. I think it should be invoked
against *.class files but I cannot see .class files in any of the views.
And I don't find other menu options that I can use...

I am still a beginner. Thanks for listening to me and can you help me?

Regards
Chunsheng Tang

Follow the class you are interessted in by e.g. clicking on in holding the ctrl key.

Try drilling into a JAR holding class files which doesn't have a source
attachment and opening one of the classes - JadClipse should give you a
decompiled code view instead of the normal error message with disassembly.
If that works, you've got it installed right, and if not, you haven't.

Now, it sounds like what you want to do is to see a decompilation of your
own code. To do that, you'd have to find your own class files, but Eclipse
hides these away somewhere. I'm not sure if it's somewhere visible to you
- it might be visible in the resource view, but hidden in the java view.
Or not. Check your build path settings and properties, and see if you can
find a setting for where the compiled classes go (i think it's usually
$PROJECT/build/classes or something like that, BICBW). Even if you find
them, Eclipse might treat your source code as being the attached source of
those classes, and show that instead of invoking JadClipse. Your safest
option will be to jar up the class files (from the command line, probably,
although there's probably a way to do a binary-only export from Eclipse)
and drop them into a fresh project, away from the sources.

Probably correct.

Hi Tom

Thanks for your hints. The JadClipse can decompile the libraries I
import, but not the *.classes I created (The navigator explorer can show
*.class files of my project).
