Java Server Pages compile to Servlets, I suppose it's really correct to 
describe Tomcat as a 'Servlet Engine', or 'Servlet Container' but it's 
more than that, it's a pukka web server as well. When I started to use 
Tomcat it was mostly used as a Servlet Engine behind an Apache httpd 
front end ... and many people still use it that way. However over the 
years the performance has improved so much that personally I can do 
without the overhead of configuring Apache and focus instead on 
configuring Tomcat. My Tomcat servers listen on port 80 just like Apache 
httpd and serve static content as well as dynamic. I have the container 
managed data sources configured and access them via a JNDI lookup just 
like the heavyweight servers. The kind of things I can't do OOTB are 
host entity/stateful/stateless session beans or host remote interfaces 
via RMI-IIOP. There is no built in messaging or support for distributed 
transactions(last time I looked), however given that most of these 
things were designed to provide scalability and given that memory is now 
so cheap and server performance is now so good I see little point in the 
added complexity of an application server. Servlets and jsps are all 
part of J2EE or whatever it's called now so I suppose you *could* call 
Tomcat a lightweight app server.

I mostly do smaller business applications now, a few hundred visitors a 
day no more than 1000 concurrent sessions but otherwise a full blown 
database backed business application and I have never had any problems 
with performance. I guess it depends on what you intend to do and how 
you see the application scaling in the future.
