问题 I am converting a JSP/Servlet dynamic web project to Struts 2 and the custom error pages (that previously worked with the JSP/Servlet version) have stopped working. When I induce a 404 error by accessing a non-existent page like abc.jsp , it throws below exception: SEVERE: Servlet.service() for servlet jsp threw exception 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

问题 I'm trying to point a button in my form tag to a different action/action class than the form but it won't work. I read in another thread that this is due to a bug in Struts 2 and that struts.mapper.action.prefix.enabled"="true" should be set, so I did it but it's still the same. I can use a different action pointing to a different method of the same action class that the form is using but when I try specifying a different action class it doesn't work. This works, (jsp) <s:form action="print">
