        <br>
        说明： <br>
        Jsp1.1提供给开发者自己编写Tag的机会，从而使得JSP与HTML的混排更简单，更容易实现<br>
        Server端的MVC结构（Model2）. <br>
        本站提供了一个非常简单的Custom Tag,您可以试试。<br>
        运行环境为Tomcat <br>
           1 下载的war 文件放到%TOMCAT_HOME%\webapps\下 重新启动tomcat  <br>
           2 访问 http://localhost:8080/jdeveloper 即可  <br>
        
        谢谢访问。    <br>
