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
<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

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.
