我正在使用 netbeans 开发一个 jsf Web 应用程序。

    <fieldset>
        <div>
           <h:inputText id="firstname" value="#{loginCtrl.customer.name}" label="Name">
                  <f:validateLength minimum="3" maximum="8"/>
           </h:inputText>
        <div>
...

我编写了该代码，但是当我将它部署到 apache tomcat 服务器时，没有显示任何字段？为什么？h:input 没有可见性元素？

提前问候和谢谢

确保您在浏览器地址栏中看到的请求 URLFacesServlet与web.xml. 您可以通过在浏览器中右键单击页面并查看生成的 HTML 源来验证这一点。如果<h:inputText>仍然存在，则意味着FacesServlet根本没有调用 。

If you open the page by /page.xhtml, then the FacesServlet is apparently not mapped on *.xhtml, but on *.jsf or something else. You'd need to change the URL in browser's address bar accordingly to match exactly the specified URL pattern, or to fix the mapping accordingly.

h:input has no visibility element?

是的，该h:inputText元素具有rendered属性：

<h:inputText id="firstname" rendered="true" value="#{loginCtrl.customer.name}" 
    label="Name">
      <f:validateLength minimum="3" maximum="8"/>
</h:inputText>

但是默认值是正确的，所以问题不在于...
