287<h3>Deploy a Directory or WAR by URL</h3>

289<p>Install a web application directory or ".war" file located on the Tomcat
290server. If no <i>Context Path</i> is specified, the directory name or the
291war file name without the ".war" extension is used as the path. The
292<i>WAR or Directory URL</i> specifies a URL (including the <code>file:</code>
293scheme) for either a directory or a web application archive (WAR) file. The
294supported syntax for a URL referring to a WAR file is described on the Javadocs
295page for the <code>java.net.JarURLConnection</code> class.  Use only URLs that
296refer to the entire WAR file.</p>
297
298<p>In this example the web application located in the directory
299<code>C:\path\to\foo</code> on the Tomcat server (running on Windows)
300is deployed as the web application context named <code>/footoo</code>.

342<h3>Deploy using a Context configuration ".xml" file</h3>
343
344<p>If the Host deployXML flag is set to true, you can install a web
345application using a Context configuration ".xml" file and an optional
346".war" file or web application directory. The <i>Context Path</i>
347is not used when installing a web application using a context ".xml"
348configuration file.</p>
349
350<p>A Context configuration ".xml" file can contain valid XML for a
351web application Context just as if it were configured in your
352Tomcat <code>server.xml</code> configuration file. Here is an
353example for Tomcat running on Windows:
354<div align="left"><table border="0" cellpadding="0" cellspacing="4"><tr><td height="1" width="1" bgcolor="#023264"><img border="0" hspace="0" vspace="0" height="1" width="1" src="./../images/void.gif"></td><td height="1" bgcolor="#023264"><img border="0" hspace="0" vspace="0" height="1" width="1" src="./../images/void.gif"></td><td height="1" width="1" bgcolor="#023264"><img border="0" hspace="0" vspace="0" height="1" width="1" src="./../images/void.gif"></td></tr><tr><td width="1" bgcolor="#023264"><img border="0" hspace="0" vspace="0" height="1" width="1" src="./../images/void.gif"></td><td height="1" bgcolor="#ffffff"><pre>
