配置web.xml 例如:
<?xml version="1.0" encoding="UTF-8"?>
<!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>helpservlet</servlet-name>
    <servlet-class>gcwh.helpServlet</servlet-class>
  </servlet>
  <servlet>
    <servlet-name>mediaservlet</servlet-name>
    <servlet-class>gcwh.mediaServlet</servlet-class>
</servlet>
.............. <servlet-mapping>
    <servlet-name>helpservlet</servlet-name>
    <url-pattern>/helpservlet</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>mediaservlet</servlet-name>
    <url-pattern>/mediaservlet</url-pattern>
