3.3 Testing Tomcat

The Tomcat installation directory contains a number of subdirectories. All of them are described in the README.txt file, but the most important ones are:


Scripts for starting and stopping the Tomcat server.


Tomcat configuration files.


Default location for web applications served by Tomcat.

Two more subdirectories under the Tomcat home directory are created the first time you start the server:


Server log files. If something doesn't work as expected, look in the files in this directory for clues as to what's wrong.


A directory for temporary files created by the JSP container and other files. This directory is where the servlets generated from JSP pages are stored.

To test the server, run the startup script as described in the platform-specific sections, and (assuming you're running Tomcat on the same machine as the browser and that you're using the default 8080 port for Tomcat) open a browser and enter this URL in the Location/Address field: http://localhost:8080/.

The Tomcat main page is shown in the browser, as in Figure 3-1. You can now run all examples bundled with Tomcat to ensure everything works.

Figure 3-1. The Tomcat main page

If you're trying this on a machine that sits behind a proxy—for instance, on a corporate network—and instead of Tomcat's main page you see an error message about not being able to connect to localhost, you need to adjust your proxy settings. For Netscape and Mozilla, you find the proxy settings under Edit Preferences Advanced Proxies, and for Internet Explorer, you find them under Tools Internet Options Connections > LAN Settings. Make sure that the proxy isn't used for local addresses, such as localhost and

When you're done testing Tomcat, stop the server like this:

C:\Jakarta\jakarta-tomcat-5.0.18\bin> shutdown
