Tomcat

I’ve been using Tomcat in all the previous chapters to show you examples of servlets, JSP pages, and documents. Now it’s time to talk about Tomcat itself.

Tomcat, an open-source Servlet/JSP server/container from Apache foundation, is essentially three things:

?A web server

?An application that executes Java servlets

?An application that converts JSP pages and documents into Java servlets

In this chapter, I’ll describe the basics of Tomcat’s architecture and its directory structure. I’ll then show you examples of how to do a couple of useful things.

At the moment of writing this chapter, the latest release of Tomcat is 7.0.28, which runs on Java SE 6 (or later), implements the Servlet 3.0 and JSP 2.2 specifications, and supports EL 2.2.

Tomcat is a project of the Apache Software Foundation. Therefore, the authoritative source for obtaining further information on Tomcat is /, which provides extensive documentation (/tomcat-7.0-doc/).

Tomcat’s Architecture and server.xml

Tomcat’s architecture consists of a series of functional components that can be combined according to well-defined rules. The structure of each server installation is defined in the file server.xml, which is located in the conf subdirectory of Tomcat’s installation folder.

In the rest of this section, I’ll go through the components. Listing 9-1 shows the default server.xml (after removing the comments). I’ll refer to it when describing the various components.

Figure 9-1 shows how the major Tomcat components are organized in hierarchical fashion.

Context

A Context is the innermost element of a group of Tomcat components called containers, and it represents a single web application.

Tomcat automatically instantiates and configures a standard contex
