Servlet 的访问路径问题

     <servlet>

        <servlet-name>HelloServlet</servlet-name>

        <servlet-class>org.iridium.servlets.HelloServlet</servlet-class>

    </servlet>

    <servlet-mapping>

        <servlet-name>HelloServlet</servlet-name>

        <url-pattern>/hello/helloworld</url-pattern>

    </servlet-mapping>

        <form action="<%=request.getContextPath()%>/hello/helloworld">

            <input type="submit" value="submit">

        </form>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>
