英文:
jasper exception. The Struts dispatcher cannot be found
问题
我有两个JSP文件：
index.jsp（没有Struts 2标签）login.jsp（带有Struts 2标签）
我用<a href="login.jsp">LOGIN IN</a>标签将login.jsp链接到index.jsp。
当点击时，页面不加载，而是抛出错误：
(ERROR:org.apache.jasper.JasperException: 找不到Struts分派程序。).
如果从login.jsp中移除所有的Struts标签，它就能正常工作。

如何在带有Struts 2标签的情况下运行我的应用程序？
英文:
I have two JSP files:
index.jsp(with no Struts 2 tags)login.jsp(with Struts 2 tags)
I have linked to login.jsp to index.jsp with <a href="login.jsp">LOGIN IN</a> tag.
When clicked the page doesn't load, instead throws the error:
(ERROR:org.apache.jasper.JasperException: The Struts dispatcher cannot be found.).
If all the struts tag are removed from login.jsp it works fine.

如果页面上有S2标签，则必须通过操作来访问。
S2标签期望来自框架的数据。
英文:
If there are S2 tags on a page it must be reached via an action.
S2 tags expect data from the framework.
