Question

我试图让struts2与tomcat 6身份验证应用程序一起工作。我的应用程序在用户登录时工作正常。但如果用户未登录或用户被拒绝，我无法使用struts标签在我的jsp中工作（403）

有没有办法让tomcat允许访问struts调度程序而不记录？

错误记录：

GRAVE:The Struts dispatcher cannot be found.  This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]

感谢您的有用回复

我从我的错误jsp页面onload重定向到一个动作，我可以使用struts-tags

谢谢！

ACCES-refuse.jsp

 <html>
  <head>
  <META HTTP-EQUIV="Refresh" CONTENT="1;URL=acces-refuse.action">
 </html>

struts.xml中

<action name="acces-refuse" class="className">
        <result name="success">/acces-refuse-action.jsp</result>
</action>

此代码有点意大利面条代码，但有效
