We're doing exactly the same thing, except substitute Macromedia's JRun for 
Tomcat.  The Apache web server is running on its own box, for security's sake.
I believe any machine exposed to the great unwashed Internet ought to be 
considered potentially compromised and hostile.  It's in it's own 
firewalled DMZ.

The web server is an Intel Pentium ATX motherboard in a 1U chassis running 
FreeBSD 4.3.  The Apache was built to include mod_ssl to support secure 
connections.  The JRun and PostgreSQL are running on a 4 CPU Sun E3500 
under Solaris 2.6.

We had issues with Tomcat when we evaluated it, hence the JRun.  Tomcat may 
be fixed by now, and we may revisit that issue when the JRun license is up 
for renewal.  I also see no reason other than management skittishness that 
we couldn't run the backend on something like a 4 CPU 800MHz Xeon Dell 
server and FreeBSD.  We've had fewer problems with the FreeBSD than with
