求助RichFaces Greeter Demo部署不成功

[血战31天]

我根据RichFaces Developer Guide中的Getting Started with RichFaces给出的Greeter例子，总是部署不成功，
运行环境Tomcat5.5 jdk1.6.0_03
那个web.xml完全照搬的，却总是显示错误

HTTP Status 404 -

--------------------------------------------------------------------------------

type Status report

message

description The requested resource () is not available.


--------------------------------------------------------------------------------

Apache Tomcat/5.5.27


请高手们指点，

问题倒是没有解决，肯定是web.xml或faces-config.xml配置问题吧

不过，还是实现了ricefaces的demo
