[xiaohuanjie]

可能是你的环境变量的问题

[izard999]

异常提示是缺少类.! LZ请确认下是否差包

[xiaohuanjie]

LZ重启一次Myeclipse试试，

如果不行的话就检查环境变量

[亲努力啊]

找不到类

[chick56]

环境变量?? 具体是?? 顺便把xml贴出来. 会不会跟我用Tomcat5.5有关系?

[chick56]

就是那个报错没说找不到哪个类啊, 知道就好办好多了. 它就是一个filter, 空白什么都没有

[lq282514781]

应该是环境变量

[chick56]

环境变量? eclipse的? 要怎么设置呢? 之前没碰到过

[chick56]

要把它顶上一下

[chick56]

结贴了, 解决了, 问题是我自己的filter错了, 所以说找不到filter...
搞了大半天, 兜了个大圈.
谢谢大家, 完了, 结贴.
