Exemple :
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
ArrayList students = new ArrayList ();
HttpSession session = request.getSession();
String target = new String ("success");
LoginForm loginForm = (LoginForm) form;
String userName = ((LoginForm) form).getUserName();
String userPassword = ((LoginForm) form).getUserPassword();
String user = getUser(userName, userPassword);
if (user == null) {
target = new String ("login");
ActionErrors errors = new ActionErrors ();
errors.add(ActionErrors.GLOBAL_ERROR, new ActionError (
"errors.userNotFound", userName));
saveErrors(request, errors) ;
}
else {
session.setAttribute("USER :", user);
}
return (mapping.findForward(target));
}
And in your jsp view you will need to add
a <html:errors /> tag.
Don't forget to add your message keys on your application.properties file.
Example :
userNameNotFound=<li>User name not found<li>
