The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter。
问题原因来自 http://www.blogjava.net/freeman1984/archive/2010/06/01/322478.html;
原因:如果想要在jsp文件中,采用 struts的tag,那么jsp必须是通过action跳转得到,也就是必须通过web.xml所配置的过滤器访问文件,否则会有异常。
我将filter的url-pattern由原来的/*改成了*.action.所以在jsp页面访问的时候就抛出以上异常。现在在下面加上*.jsp
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
