Help Please Cannot cast from ActionForm to StudentForm

[student study]

Hi All,
I am getting this Eroor


Cannot cast from ActionForm to StudentForm


public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
StudentService service = new StudentService();
StudentForm studentForm = (StudentForm) form; //Error
StudentDTO studentDTO = new StudentDTO();
BeanUtils.copyProperties( studentDTO, studentForm );
service.insertStudent( studentDTO );
request.setAttribute("employee",studentDTO);
return (mapping.findForward("success"));
}

I have extended Action in StudentForm class.


Any help would be greatly appreciated.

Thanks
AS

You'll have to extend ActionForm, not Action.

By the way, since "student study" is not in compliance with our naming policy, I'll have to ask you to change your display name into something valid. The display name must be your real name or a fake name that looks real and isn't otherwise obviously fake.
Thanks.

please post your struts-config.xml file.


AND


please check form type of this action in config file.

may be incorrect...

Hi venkat penmatsa,

I think your form-bean tag only mapped with LoginForm class.

and also for a request should have only one form-bean attribute that means either LoginForm bean or BankController bean

but you are casting the form object for two classes as you posted like this.

LoginForm l=(LoginForm)form;
BankController b=(BankController)form;

just put any one statement. Relevant what you mapped with the form-bean attribute.
