You need to make sure your WO is thread safe first. You also need to make
sure to turn on concurrent request handling. The servlet containers are all
multi-threaded and seem to scale pretty well. With the servlet containers
you can run multiple instances of your application by creating multiple
directories (unlike Monitor). Some containers are easier to do this with
than others. The goal is to spawn a new JVM for each instance like Monitor
does, otherwise you run out of memory pretty quickly.
The default behavior for tomcat is to have one JVM per server, if one app
misbehaves the rest die with it. Jrun makes it easy to have multiple JVMs
running concurrently.
