Question

当我尝试通过http://localhost/home/index.html访问我的开发网站时出现此错误，该网站重定向到http://localhost/home/views/main/index.xhtml：

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

我正在使用Tomcat 7.0.8，Mojarra JSF 2.0.4和Eclipse Helios。我已经检查了index.xhtml文件的WAR部署文件，它在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。

我得到的堆栈跟踪是：

我不知道为什么我会收到上述错误。有人可以帮忙吗？

Answer 1

我不知道负责重定向的代码如何，但

/views/main/index*.xhtml

绝对看起来不对。那边的星号是什么？相应地修复代码，不再在视图ID中发出此星号。

Answer 2

我解决了这个问题：这只是web.xml的配置问题。

我在web.xml中将webapp版本声明为2.0而不是Tomcat 7中的3.0。

Tomcat错误：在ExternalContext中找不到资源
