Struts2标签给出了碧玉异常

Question

下面是jsp代码

<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>

我收到此错误。 需要帮助。

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

43:             </ul>

这是我的web.xml配置-我猜问题是在Sitemesh中使用Struts标签。

对我来说，情况也是一样，碰触我也收到另一个错误。 发生的事情是在运行时替换了struts标记，因此html处理器无法对其进行编译。 解决方案是在web.xml中，struts过滤器映射必须比sitemesh过滤器映射更高。

在本主题中，我的回答是相同的：在装饰器sitemesh上未替换s：url

看一下您是否熟悉。
