问题我已经自己解决 原来我朋友用的是TOMCAT6 可以用1.2的我的TOMCAT5.5只能1.1 浪费我一天时间了 妈妈的~~

Answer 3

"java.lang.NoClassDefFoundError: javax/el/ELException"异常信息写的这么清楚看不见还是看不懂？

Answer 4

真囧啊tomcat版本还是稍微高点好 。。6.0的支持不错

Answer 5

其实很多东西，在tomcat 版本的问题里有不兼容的地方。

Answer 6

额。兼容性问题还真没注意到。MARK

Answer 7

支持16楼，我用的就是Tomcat 5.0的，就没有遇到这个问题，所以我不认为是Tomcat版本问题。
