Tomcat by itself, or Tomcat + Apache?

["Dr. Evil" <dr...@sidereal.kz>]

Tomcat is a fully-functional web server by itself.  I'm working on an
application which will have jsp on every page, and even the graphics
will be served by jsp, so it seems to me that Tomcat will be called
for every page no matter what.  In this case, do I need to use Apache
with Tomcat, or can I just use Tomcat by itself?  I am doing all this
with Tomcat 4, btw.  The application uses DB info on basically every
page.

Thanks!
