Hi I am pradeep Jain . Currently I am using Struts 1.2.X . But I am facing some problems.
1.I am trying to create my own action mapping but in Action class when ever I am try to use that it is giving me class cast exception . following is my web.xml
web.xml is not where you specify custom action mappings. You specify them on either the "action-mappings" or "action" elements. See http://struts.apache.org/userGuide/ for more details.

<servlet> <servlet-name>action</servlet-name> <servlet-class>org.apache.struts.action.ActionServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>5</param-value> </init-param> <init-param>( this is custome action mapping class) <param-name>mapping</param-name> <param-value>com.wiley.EmployeesActionMapping</param-value> </init-param> <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param>
<load-on-startup>1</load-on-startup> </servlet>
But when in my action class ... public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException { ActionMapping mapping1 = mapping; System.out.println("***********mapping .getclass"+mapping.getClass()); EmployeesActionMapping employeesMapping =(EmployeesActionMapping)mapping;( Here I am getting class cast exception )
...........
}
Please help in in resloving this ..
Thanks & regards Pradeep Jain

Subject Re: Struts-Chain Roadmap and Inevitable Cocoon Analogy
Well, you could do that with chain now by writing an action that deferred handling to a particular chain, but I do like the sitemap concept as evidenced by my porting of their wildcard matching to Struts.
It might be interesting for an alternate struts-config format that does allow us to stick chain commands right in struts-config rather than having them defined somewhere else and have it look kinda like ant:
<action-mapping path="edit*"> <authorize type="{1}" /> <retrieveFormData type="{1}" /> <generateJsp path="/jsp/{1}.jsp" forward="success" /> </action-mapping>
Personally, however, I prefer something like struts-flow which allows workflows to be defined in a more powerful scripting language. These XML mappings work great for simple cases, but don't really for the more complex workflows you'd find in a real application. I think that was one of the main reasons why Struts developers insist on one Action per request as Java is a much more capable workflow language than XML.

Struts could use a sitemap thingy to pass a request along actions (without having the action choose an ActionForward). I guess that could work by consulting the sitemap object like mapping.findForward(sitemap.getForward(request));
