我有一个带有 JSF 标记的 Facelet 文件，用于显示标签、输入字段和按钮，但当我运行它时，这些部分在浏览器中不可见。

         <h:form>
              Name:
            <h:outputLabel value="First Name:"> </h:outputLabel>
            <h:inputText id="name" value="#{DataForm.name}"></h:inputText>
            <h:commandButton value="Doctor Register" action="#{DataForm.submit}">       </h:commandButton>


         </h:form>
     </h:body>
 </html>

这是如何引起的以及如何解决？我正在使用 netbeans 6.9.1 Glassfish 3.1。

         </h:form>
     </h:body>
 </html>

How is this caused and how can I solve it? I am using netbeans 6.9.1 Glassfish 3.1.

当未调用 FacesServlet 时，可能会发生这种情况。它负责解析 Facelet 文件并完成所有 JSF 工作。

您需要确保您的请求 URL（您在浏览器地址栏中看到的 URL）与在 web.xmlFacesServlet 的 URL 模式匹配>。例如，如果它映射到 *.jsf 的 URL 模式，那么您需要确保通过以下方式在浏览器中打开该页面

http://localhost:8080/contextname/index.jsf

或者当你想调用 < code>FacesServlet 在每个 *.xhtml 请求上，那么您需要相应地更改 web.xml 中映射的 URL 模式（推荐）

<url-pattern>*.xhtml</url-pattern>

This can happen when the FacesServlet is not been invoked. It's the one responsible for parsing the Facelet file and doing all the JSF works.

You need to ensure that your request URL (the one which you see in the browser address bar) matches the URL pattern of the FacesServlet as it is been mapped in the web.xml. If it's for example mapped on an URL pattern of *.jsf, then you need to ensure that you open the page in browser by

http://localhost:8080/contextname/index.jsf

Or when you want to invoke the FacesServlet on every *.xhtml request, then you need to change the URL pattern of the mapping in web.xml accordingly (recommended)
