--------------------------------------------------------------------------------出现如上问题，jstl用的1.2，其他的包都添加在tomcat下的common中，不知道怎么解决，多谢各位！

Answer 1

5.5要加一句哈 iselignore=“false”之类的别用5.5了，用6.0

Answer 2

<%@ page isELIgnored = "false"%>

Answer 3

jsp版本呢？是否还不支持jstl呢。jsp2.0才支持吧。不知道是否是这个原因

Answer 4

Tomcat6 实现了 servlet 2.5 和JSP2.1的规范，可以支持JSTL1.2；而Tomcat5实现了 servlet 2.4 和JSP2.0的规范，只能支持JSTL1.1

Answer 5

我尝试过用jstl1.1和stander.jar，但是还是报这个错误，并且这些jar应该是放哪里啊？是tomcat\
common\lib下还是放在workspace\工程\webRoot\lib下呢？还是不管放哪，只要导入工程中就行了？谢谢解答一下。

http://albert0707.javaeye.com/blog/562969http://blog.csdn.net/ja_II_ck/archive/2009/05/27/4220102.aspx不太清楚你的具体情况，参看一下吧。

Answer 7

这两篇我都看过的，但是一直报那个错误，就是jstl中的c:forEach，一直报错，我换过jstl1.2和jstl1.1,standar.jar,页面中也做过设置，实在是没什么办法，myeclipse6.0，tomcat5.5，jdk1.6.02
，jar包应该是全的啊，就是页面中加载c:forEach久报错，挺郁闷的，多谢了啊。

Answer 8

解决，jstl1.1和standar。jar，都用上，各个地方，久好了，多谢！
