调试很多次了,找不到错误.之前用的好好的,我在服务器端改一下代码,现在报的错好奇怪哈.报错如下:

我开始写一个Filter,过了编码,发现在调用
httpReq.setCharacterEncoding("utf-8");
filterChain.doFilter(httpReq, servletResponse);
的时候就报错,但是后来我将该类全部注释,发现还是报错.
真的感觉我的代码和这个异常一点关系都没有,
请求url为:
http://192.168.1.101:8080/ServerAQI/JsonAction?fromDate=2014/01/01&toDate=2014/01/03
我发现在系统调用StandardWrapperValve.invoke(Request, Response) line: 270的时候就报异常.
这时我自定义的过滤编码的类已经全部注释了.
------解决思路----------------------
是不是修改后没重启tomcat？代码没更新？
------解决思路----------------------
正常，有时编译器神经病，重启一下就好。
------解决思路----------------------
clean下或者重启下

toDate=2014/01/03 中的"/"这个符号的问题 吧？
