Let's look at what we've done. We took our productionalized Tomcat installation and added autostart capabilities so that Tomcat starts when the machine boots. We also got an introduction to Web application resources and what their management entails. In this case, we had to take care of the installation and configuration of the database, as well as the configuration of the JNDI data sources and actual coding of the application (just a JSP). Obviously, a larger IT shop probably has one or more people responsible for the database, so your job as a Tomcat administrator is somewhat smaller.
In the next chapter, I'll talk about a very important subject, security. We'll add some basic authentication and protection to your Tomcat installation. Then, we'll move on to application development, where I'll be discussing various methodologies and technologies for creating Tomcat applications.
