Tomcat is an open source web server that processes JavaServer Pages and Java Servlets. It can run as a stand-alone server or be integrated with Apache. Like Apache, the core Tomcat program is relatively simple, but there are many enhancements that can be added that make it much more complex. You will learn how to integrate Tomcat with the Apache HTTP server (and the situations when you should and you shouldn't), how to set up database connectivity through JDBC, and how to ensure your web applications are secure. It will also cover some of the tools that can be integrated with Tomcat, such as Ant (for automatically building web applications) and Log4J (for advanced logging). «
