I'm not asking you to look at the elisp. That's my job. Apparently, the
JDK 1.2.2 and JDK 1.3 plugins for browsers (available from Sun) accept
being attached to a JPDA-based debugger, e.g., JDEbug. So why don't you try
installing one of the plugins, starting it with the necessary debug options
(see Chuck Irvine's message), and try attaching JDEbug to the plugin (see
the JDEbug documentatiion). In principal this should allow you to debug
applets running in Netscape (does IE support the JDK plugins?), using
JDEbug. You can contribute by verifying whether this is possible and
letting the rest of us know if you running into any problems.
