Question

我使用JSF 2.2在Eclipse中创建了一个简单的Web应用程序，并通过WebSphere 8.5运行它。但是，当我使用http://localhost:9082/HCVA/index.xhtml在浏览器中向上拉索引页时，我只会得到一个空白页。我只使用JSF标签编写了整个网页，当我在调试器中查看时，我发现JSF标签未呈现为HTML。如果我添加了<p>test</p>之类的HTML标记，那么它会在浏览器中显示“测试”。这是到目前为止的整个索引页面：

<?xml version='1.0' encoding='UTF-8' ?>

我看过其他有关此的文章，并且我知道这个问题可能意味着该页面未通过FacesServlet传递。但是，我已验证所使用的请求URL与FacesServlet的url模式匹配。这是我的web.xml的样子：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        Monitors Faces JSP files for modifications and synchronizes a running server with
the changes without restarting the server. If this parameter is set to false or
removed from the deployment descriptor, any changes made to Faces JSP files may
not be seen by the server until it is restarted. This parameter is usually set
to true while the Faces JSP files are being developed and debugged in order to
improve the performance of the development environment.</description>

        Load JSF runtime when the application server starts up. If this parameter is set to false or removed,
JSF runtime will be loaded and initialized when the first JSF request is processed.
This may disable custom JSF extensions, such as factories defined in the project.</description>

长期对它进行故障排除，没有结果。任何帮助，将不胜感激。

WebSphere 8.5不提供JSF 2.2实现，仅提供通过SunRI的JSF 1.2和通过MyFaces的JSF 2.0。除非您提供第三方JSF实施，否则将需要更新您的应用程序以使用正确的JSF规范级别。

JSF标签未呈现为HTML
