Java Servlet Server related info

Tomcat can be run as a standalone server. Tomcat can also be run as an add-on to the Apache HTTP Server (or Microsoft IIS) - as the Java servlet/JSP container. In this combination, Tomcat executes the Java servlets and JSPs, the Apache serves the static HTML pages and performs other server-side functions such as CGI, PHP, SSI, etc. Read "Why should I integrate Apache with Tomcat? (or not)" at Tomcat FAQ (http://wiki.apache.org/tomcat/FAQ/Connectors#Q3).
