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>

<h1>Test Applet</h1>
Press the start button to decompile this applet. You may change the
class 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>
Save doesn't work in Netscape because the FileDialog is missing
there. But access to local files is most probably forbidden
anyway. <br>
You may give multiple entries in the class path field separated by a
comma. The components may also be local zip or jar files, but that is
probably forbidden by the browser. <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.
BTW: If you just want to read the source, you may <a
href="jode/">browse it online</a><br>
<applet code="jode/JodeAppletOneZero.class" codebase="./" width=640 height=400>
<param name=classpath
value="http://nirwana/~jochen/">
value="http://www.informatik.uni-oldenburg.de/~jochen/">
<param name=class value="jode.JodeAppletOneZero">
</applet>
You may run this locally; you need at least a java 1.1 compatible
virtual machine and the <a href="jode_cls.zip">decompiler classes</a>.
The entry class is <code>jode.JodeWindow</code>, so you may start it
under SUN JDK with (the exact commands depend on your operating
system, java virtual machine, shell etc):
<pre>
set CLASSPATH=jode_cls.zip
java jode.JodeWindow
</pre>
