Subject: Re: relation between "validate", validate method and perform
method
If validate is set to true in the struts-config.xml,
then the ActionServlet will automatically call the
validate method in your ActionForm for you. If there
are errors, it will return you to your input
attribute's URL. If there aren't any errors, it will
call your perform method. If you need to forward your
form to different pages based on the validation, you
should have validate="false" and just call the
validate method yourself inside your perform method.
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
ActionErrors errors = form.validate(mapping,
request);
if (errors != null && errors.empty()) {
return mapping.findForward("success");
} else if (errors.size("lastName") > 0) {
return mapping.findForward("failureLastName");
} else {
return mapping.findForward("failure");
}
}
