Re: Applet problems

[Morgan Kita <mkita(at)verseon(dot)com>]

java is my codebase directory in relation to my directory structure.
When I attempt to run the applet in firefox, the pages are being served
by cherrypy. So my html looks like:

<applet code=MyClass.class codebase=java
archive="myjar.jar"
width=460 height=160>
</applet>

Therefore it searches java/org/...
