Servlet中web.xml 配置问题，求解！！！

<servlet>


    <servlet-name>InitParameterServlet</servlet-name>


    <servlet-class>cn.tp.servlet.InitParameterServlet</servlet-class>


    <load-on-startup>0</load-on-startup>


    <init-param>【 在eclipse中这段代码出现红下划线 但是去掉<load-on-startup>0</load-on-startup>下划线又消失了，应该是没问题的，但是不知道怎么解决。】


        <param-name>ref1</param-name>


        <param-value>ggzz</param-value>


    </init-param>  


    <init-param>


        <param-name>ref2</param-name>


        <param-value>zz</param-value>


    </init-param>


  </servlet>


 <servlet-mapping>


    <servlet-name>InitParameterServlet</servlet-name>


    <url-pattern>/servlet/InitParameterServlet</url-pattern>


  </servlet-mapping>
