有想探讨Java Web方面的同行吗？ 看了一下 google group，发现没有几个这方面的group，所以我创建了一个，希望找一些同行们，能够一起高质量探讨技术问题。感兴趣的请加，不感兴趣的就抱歉打扰了

看看后台日志，你请求拦截的地址看看输出什么了？

另外appengine上
http://code.google.com/intl/zh-CN/appengine/docs/java/config/webxml.html#Filters
doFilter方法签名为何与 java servlet api 不一致呢？ 是文档错了，还是我这
里实现的 Filter 接口不对？
public void doFilter(HttpServletRequest request,
HttpServletResponse response,
FilterChain filterChain)
throws IOException, ServletException {

不会被截获的，不存在的uri会被截获。 *.do 也是如此，文件不存在的时候才会
被截获。
url-pattern写成 /xxx/* ，都会被截获。
妈的，难道这是 google api 故意这么设计的？ 之前没发现有这样的问题
