Tomcat错误：在ExternalContext中找不到资源

当我尝试通过http：//localhost/home/index.html访问开发站点时收到此错误，该站点重定向到http：//localhost/home/views/main/index.xhtml：

java.io.FileNotFoundException: /views/main/index*.xhtml Not Found in ExternalContext as a Resource

我正在将Tomcat 7.0.8和Mojarra JSF 2.0.4与Eclipse

Helios结合使用。我已经检查了WAR部署文件中的index.xhtml文件，并且该文件位于WAR文件中。我还检查了../wtpwebapps/home/views/main目录，可以看到Eclipse已经部署了index.xhtml文件。

我得到的stacktrace是：

    07/02/2011 3:58:53 AM org.apache.catalina.core.StandardWrapperValve invoke

我不确定为什么会出现上述错误。有人可以帮忙吗？

回答：

我解决了问题：这只是web.xml的配置问题。

我在web.xml中将webapp版本声明为2.0，而对于Tomcat 7，则声明为3.0。
