最好点击按钮跳转，出现如下提示：
找不到请求的资源。 http://localhost:8080/zh/web/guest/AddUserStoryCard.action当然，我的控制台也报错，但没有影响显示我也没有管理，不知道是否与错误有关:

Answer 2

现在正在做一个liferay项目，其中也涉及到跳转的问题，其中跳转应该使用绝对路径：例如我们的跳转路径为：/html/portlet/adManager/error2.jsp，希望对你有用。

Answer 3

http://localhost:8080/zh/web/guest/AddUserStoryCard.action应该是命名空间不对导致的/zh/web/guest是什么意思

Answer 4

给你的action加个命名空间，struts.xml中也定义，portlet.xml中也要定义该命名空间，例如action所在命名空间为view
<init-param>
            <name>viewNamespace</name>
            <value>/view</value>
        </init-param>        <!-- The default action to invoke in view mode. -->
        <init-param>
            <name>defaultViewAction</name>
            <value>index</value>
        </init-param>

Answer 5

楼主贴的这些 丝毫看不到跟Liferay有关的配置

Answer 6

根据你的访问路径它应该找不到相应的namespace吧？然后就进入xml找相应的jsp页面中连接strut2中action是不是直接访问的action中的name是否有误
