使用Eclipse Helios，我尝试启动一个基于JSF的项目。
在创建了一个新的工作区之后，我安装了web-tools-platform的东西。所有这些都使用了帮助菜单中的“安装新软件”，这工作得很好。
为了开始为我的项目进行开发，我使用向导创建了一个新项目，我下载并安装了Tomcat 6.0示例和运行时，并使用预设的“JavaServer Faces v1.2项目”对其进行了配置。
我创建了一个index.jsp文件（向导中也使用了JSF-template），并在其上放置了一个JSF-outputText。
Deploy到tomcat似乎可以工作。当在浏览器中调用index.jsp时，我多次遇到以下异常：

我所做的每一步都是一个标准的点击向导过程。
你知道为什么这不管用吗
如果有帮助的话，我可以很容易地贴出屏幕截图或文件摘录，尽管我在这里不这样做是为了避免问题过载。

***Edit：web.xml***此文件直接来自eclipse，我没有修改它，只是删除了description-tags以缩短整个内容：

已经尝试将url模式设置为<url-pattern>/*</url-pattern>，但随后出现异常java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config
