现在，我使用jsf、spring和ibatis编写示例应用程序。我使用facelets并编写template.xhtml、header.xhtml、menu.xml、login.xhtml和主页。登录后发现这个错误。

在浏览器中，

Setter not found for property class
  + Stack Trace
  + Component Tree
  + Scoped Variables

在控制台中，

我的template.xml，

<div class="head">    
   <ui:include src="header.xhtml"></ui:include>
   <div>
     <table border="0" class="normal" height="500px" align="center" bgcolor="#F4FFE4"> 
       <tr>
         <td width="13%">
           <ui:include src="menu.xhtml" /> 
         </td>
         <td width="87">
           <ui:insert name="body" />
         </td>
       </tr>
      </table>
   </div>
   <ui:include src="footer.xhtml"></ui:include>

我的主页(SPAR02.xhtml)，

<ui:define name="head">
    <title>Top Menu</title>
   </ui:define>
   <ui:define name="body">
    <font size="5">Welcome</font>
         You can search user informations, update or delete them and can add new user.
    </ui:define>

我找不到问题所在，任何人都可以帮助我。

最佳答案

Facelets 尝试将属性 class 设置为不接受此属性的组件。大多数时候，HTML class 属性的属性是 styleClass。

我在您提供给我们的代码中没有看到问题。问题可能出在 Facelets 页面的任何位置。
