转发到静态文件没有问题，但转发到jsp或者action就会出现错误
转发到action报404错误
转发到jsp报标签错误，错误信息如下：

不太明白到底是怎么了，希望大家给支招
[b]问题补充：[/b]
可是我的过滤器必须在最开始执行
[b]问题补充：[/b]
能不能有什么办法可以解决这个冲突呢？我尝试将我的Filter写在最后面，这样写之后除了转发的目标和action可以访问外，其他资源的全部不可以访问，连js都不可以访问
[b]问题补充：[/b]
最终我没有在过滤器中转发到action，而是转发到html，然后通过ajax请求action，绕了好几个湾，感觉很是不爽，不知道shizone有没有好的办法不用绕弯呢
