最近看了JSF感觉不错，我自己的机子只装了Tomcat5
在Tomcat5下跑起来没有问题，所以我在项目里也采用了JSF
现在要移植到websphere5下去，怎么也不成功！
出现错误：

到网上找了好多资料说在web.xml中加侦听器：
<listener>
<listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>
结果还是一样的错误！！

有个讨论，和你的情况类似，希望对你有帮助。
用过JSF，没用过WEBSPHERE，没有遇到过你这种问题。

>准备直接问IBM的人，到底是不是websphere5.0的问题
这是个好方法，他们总该能解决吧
