Thanks, Danny! I have tried every suggestion made to no avail - I still
cannot get the bean to instantiate via the servlet. I know I am doing
something st00pid, but I haven't figured it out yet. And though I have
trashed JRun on this list over the years, I am (forced) running 3.2 now and
I actually find it okay (developing on Win2K; deploying to Apache). Stay
away from the proprietary API, though. - even though there are a lot of
convenience classes, you will get screwed if you try to port your app to a
non-JRun architecture. Still, Allaire has improved JRun a lot since 3.0.
Cheers!
Mark
