今天发现了一个折磨我一天的问题：

在jsp文件中使用

一直报错：

但是输出单个变量没有问题，只是使用forEach时候出错

我是用的环境是：JDK1.6+tomcat1.6

解决办法：删除jstl1.2的依赖，然后添加1.1.0的依赖和standard1.1.0的依赖

pom.xml的文件修改为：


         
      
       javax.servlet
          
      
       jstl
          
      
       1.1.0
          
      
       jar
          
      
       compile
      
     
         
      
       taglibs
          
      
       standard
          
      
       1.1.0
