The problem you mention is not specific to Jonathan, it is certainly
related to the specification of the codebase and archives, but I am not
at all a specialist of applets. When I tried to have applets work with
the Java plugin, I had to
use a tool that modified the applet to make it use the plugin. Is it
still the case, and if so, did you use that tool ?
