At least 3 years of giving a chance are not "soon"... ;]

True of false? True... in Windows 95 :-) Few years later
even Microsoft handles apps erros successfully.

Tomcat is the only server-type software I know that
_any_user_ can crash so easily and the only
that is so helpless about handling their erros.
Why don't it send 500 status to pages in faulty webapp
and contiunes to serve other webapps normally?

I use Apache Foundation apps ;]

I'm so sad that I think of a _completly_ new code. In PHP!

This is probably imposibble because:
- the apps have _plenty_ of different urls.
- I can't reproduce such Tomcat hangs on development machine.
- Shall I really examin and monitor the production enviroment?
  What about performance then?

Are there any resource monitors built-in into Tomcat?
I've browsed the JMX management manual.. well is it written
for a human being? Looks like a "finish it yourself" thing. :|
