Assuming your application is written and tested, yes. I'm running a
servlet/tomcat/mysql application that currently has 3000 users. The real
question is not "how many users" but "how many concurrent users". My app
has never seen more than 50 simulataneous users, and works fine on a Sun
SPARC E-250.

Again, simultaneous users/sessions is the key. I'm looking at upgrading
to a 2-4 CPU machine, possibly Intel architecture as we ramp up to 20000
users in the next year. No OS has been chosen yet (probably a unix flavor).

Waste of money and time. As someone else said - build your own and
co-locate if necessary. Even if you did manage to get someone able to
install/support tomcat and mysql, you'd probably pay through the nose
for actual support (i.e. when something goes down). Far better to be in
total control. PC's are not expensive, and a good OS
(unix/linux/solaris) is not expensive. Co-locate? probably expensive,
but still cheaper than what you would pay for REAL hosting (i.e. that
worked when things broke). Cost of building your own and KNOWING what's
going on... priceless.

I doubt it. Most ISP's cannot even support PHP or perl, let alone
tomcat/mysql/java.

Sorry to say this, but spend time with the docs and spend time doing the
builds yourself.

As long as you don't want to integrate Apache and Tomcat, you can email
me. I will not put both on the same machine, after finding that the web
server was killing tomcat performance (due to the number of web hits). I
split Apache off to it's own server, and used a simple firewall
(appliance) to forward port 80 requests to one machine, with port 443
(SSL) to the tomcat server. Secure application access, no hit from the
web server.
