  我们通过以上代码，虚拟出一些数据，供页面的标签调用，在实际项目中，可改为由数据库读取。
index.jsp：<%@page contentType="text/html;charset=gb2312"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>                                                                                                                                                                                                                                           
  
index.jsp：<%@page contentType="text/html;charset=gb2312"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>                                                                                                                                                                                                                                                          前进      
  我们通过标签，把一个可以显示的表格，保存到session对象的属性中，到下一页显示。 show.jsp：<%@page contentType="text/html;charset=gb2312"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>                                                
  注意这里的escapeXml="false"属性，如果为true，则会把HTML标签显示在网页里。
index.jsp：<%@page contentType="text/html;charset=gb2312"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>                                                                                      ${student.sname}
                                    
 
index.jsp：<%@page contentType="text/html;charset=gb2312"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>                                                                                                                                                                                                                                                                                              ${student.sname}
          
  
index.jsp：<%@page contentType="text/html;charset=UTF-8"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>                                                                 ${i} •                    
  以上是简单的定义变量，指定其变化范围，循环显示。 index.jsp：<%@page contentType="text/html;charset=gb2312"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>                                                                
                    
      这个例子与的类似，只是在循环时可以指定起始位子和步长。 本文来自CSDN博客，转载请标明出处：http://blog.csdn.net/sony87615/archive/2009/10/15/4675501.aspx
