Struts2的標籤給碧玉例外

下面是JSP代碼Struts2的標籤給碧玉例外

<ul class="nav pull-right"> 
      <s:if test="%{curUser != null}"> 
       <li class="dropdown"> 
       <a href="javascript:void(0)" class="dropdown-toggle" data-toggle="dropdown">%{curUser.userName}<b class="caret"></b></a> 
       <ul class="dropdown-menu"> 
        <s:if test="%{curUser.admin eq true}"> 
        <li><a href="/admin" title="Admin Section"><i class="icon-certificate"></i> Admin</a></li> 
        </s:if> 
        <li><a href="/user/%{curUser.userName}" title="%{curUser.userName}'s Profile"><i class="icon-user"></i> Profile</a></li> 
        <li><a href="/user/profile.html?action=edit"><i class="icon-cog"></i> Edit Profile</a></li> 
        <li><a href="/login.html?action=logout"><i class="icon-off"></i> Sign out</a></li> 
       </ul> 
       </li> 
      </s:if> 
      <s:else> 
       <li><a href="/login">Login</a></li> 
       <li class="divider-vertical"></li> 
       <li><a href="/signup">Sign Up</a></li> 
      </s:else> 
     </ul>

我得到這個錯誤。需要幫助。

org.apache.jasper.JasperException: An exception occurred processing JSP page /decorators/base.jsp at line 45 

42:    </a></li> 
43:    </ul> 
44:    <ul class="nav pull-right"> 
45:    <s:if test="%{curUser != null}"> 
46:     <li class="dropdown"> 
47:      <a href="javascript:void(0)" class="dropdown-toggle" data-toggle="dropdown">%{curUser.userName}<b class="caret"></b></a> 
48:      <ul class="dropdown-menu">

這裏是我的web.xml配置 - 我想問題是使用Struts標籤sitemesh。

    <filter-name>sitemesh</filter-name> 
    <filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>

'CurUser'是否存在於值棧中？ – orique 2012-08-04 20:49:16

其他的Struts2 jsps渲染是否正確？ – rees 2012-08-04 22:33:48

使用標籤確保curUser對象在valuestack中可用。或者，如果頁面正常渲染，則刪除（if-else）塊問題是curUser在valueStack中不可用。 – 2012-08-05 14:00:23

這對我來說也是如此，觸摸我也接受了另一個錯誤。會發生什麼情況是struts標籤在運行時沒有被替換，所以它不能被html處理器編譯。解決方法是，在web.xml中，struts過濾器映射必須高於sitemesh過濾器映射。

我得到的回答爲同一本主題： s:url not replaced on decorator sitemesh

看看因爲如果這聽起來熟悉。
