Problem with DispatchAction.

[peter aerts]

Hello.
I am getting this error when I am trying to call a Action which has extended a DispatchAction.
Request[/admin] does not contain handler parameter named action.

 
 if (list.size() > 0) {
				employeesDTO = list.get(0);
				request.getSession().setAttribute(Constants.USER, employeesDTO);
				request.getSession().setAttribute(Constants.USER_TYPE,
						UserType.admin);
				return mapping.findForward("admin");  

The Class AdminAction is as follows:

public class AdminAction extends DispatchAction {
	Log log = LogFactory.getLog(AdminAction.class);

	public ActionForward menuList(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) {
		//AdminForm adminForm = (AdminForm)form;
		log.info("log menuList");
		return mapping.findForward("adminMenu");
	}
}    

The struts-config is as follows:

  		

	<global-forwards>
		<forward name="login" path="/login.jsp" />
		<forward name="logout" path="/logout.jsp" />
		<forward name="hod" path="/hod.do" />
		<forward name="student" path="/student.do" />
		<forward name="admin" path="/admin.do" />
	</global-forwards>

<action
			attribute="adminForm"
			input="/login.jsp"	
		    name="adminForm"
		    parameter="action"
		    path="/admin"
		    scope="request"
		    type="com.university.struts.action.AdminAction" >
		<forward name="adminMenu" path="/admin/admin_menu.jsp" />
		</action>  

Please Help me.
thank you.

Request[/admin] does not contain handler parameter named action

Is this your comlete Actionclass AdminAction ? I think you missed the declare and implement the method called "action" as specified in "parameter" attribute in action tag.


parameter="action"

Check out this
DispatchAction for more information.

thank you Balu Sadhasivam for your responce.
yes this is my complete AdminAction.
as you can see in action tag,i have parameter="action".

Does the request contain the "action" parameter?

[Merrill Higginson]

I don't know if this is causing the problem you're currently experiencing or not, but one should never use the name action for the parameter used in DispatchAction. The reason for this is that in HTML, a FORM has an action parameter, which is the URL to be executed when the form is submitted. Therefore, having an input element named "action" can confuse things and cause strange errors. Use some other name such as "actionMethod".

[David Newton]

How can a parameter named "action" can interfere with a form tag's "action" attribute?

Thank you everybody for your ideaes.
I found the problem.
I use the dispatchMethod to dispatch to the specified method(menuList method of AdminAction class)at this program and everythings is ok now.

 
protected ActionForward dispatchMethod(ActionMapping mapping,
			ActionForm form, HttpServletRequest request,
			HttpServletResponse response, String name) throws Exception {
                       .
                       .
                       .
                       .
if (flag) {
	         return super.dispatchMethod(mapping, form, request,response, name
            }
	return menuList(mapping, form, request, response);

}  

dispatchMethod is in the AdminAction class too.
