This page describes how the Tomcat server starts up.  There are several
different ways to start tomcat, including:
</p>
<ul>
  <li>From the command line.</li>
  <li>From a Java program as an embedded server.</li>
  <li>Automatically as a Windows service.</li>
</ul>

A text description of the startup procedure is available
<a href="startup/serverStartup.txt">here.</a>

<p>
The startup process can be customized in many ways, both
by modifying Tomcat code and by implementing your own
LifecycleListeners which are then registered in the server.xml
configuration file.
