jsp error message not displaying

Question

on JSP when I want to display error messages but when it returns to JSP page by

<form:errors path="arnNumber" cssClass="error" /></span>

it is giving me an exception

org.springframework.context.NoSuchMessageException: No message found under code 'ARN number is required.contactUsUtil.arnNumber' for locale 'en_US'.

Answer 1

Literally translated, it just means that it cannot find any message associated with the following key

ARN number is required.contactUsUtil.arnNumber

in the message bundle as definied in the messageSource attribute of your applicationContext.xml.

The key looks suspicious :)
