Example Application Deployment Descriptor

Synopsis

Example F-2 shows an example of a deployment descriptor (web.xml) file:

Example F-2. Example deployment descriptor file

<?xml version="1.0" encoding="ISO-8859-1"?>
  
<!DOCTYPE web-app PUBLIC
    "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">
  
<web-app>
  <servlet>
    <servlet-name>
      purchase
    </servlet-name>
    <servlet-class>
      com.mycomp.servlets.PurchaseServlet
    </servlet-class>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>
      purchase
    </servlet-name>
    <url-pattern>
      /po/*
    </url-pattern>
  </servlet-mapping>
</web-app>

At the top of the file, you’ll find a standard XML declaration and a DOCTYPE declaration, specifying the DTD for this file. The <web-app> element then follows with a <servlet> element that defines a servlet named purchase, and a <servlet-mapping> element that maps the servlet to the /po/* path prefix pattern.
