Press enter in the class name field to decompile this applet. You may
change the class path and name to point to an class file of your
choice. But note that most browsers doesn't allow loading files from
a different server.<br>
You can download <a href="jode/jode-applet.html">HTML-file</a> and
this <a href="jode_cls.zip">archive, if you want to test it yourself.
You should use the appletviewer in this case.
