we can create Action Error object and save the error message in our action class and we can do the validation what ever we want

errors.add(ActionErrors.GLOBAL_MESSAGE, new ActionMessage("test","test1"); saveErrors(request, errors);
 
With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
