<servlet> 
    <servlet-name>default</servlet-name> 
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class> 
    <init-param> 
        <param-name>debug</param-name> 
        <param-value>0</param-value> 
    </init-param> 
    <init-param> 
        <param-name>listings</param-name> 
        <param-value>false</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 


把listings选项改为true就可以了。

org.apache.catalina.servlets.DefaultServlet支持许多配置选项，在这个web.xml文件里面都有注释。
