Spring : message.properties file not working

Question

In my validation process of application, i used message.properties file to show custom message . But it is not working and shows the following error in App Engine server log as

org.springframework.web.servlet.tags.RequestContextAwareTag doStartTag: No message found under code 'notmatch.password' for locale 'en_US'. org.springframework.context.NoSuchMessageException: No message found under code 'notmatch.password' for locale 'en_US'.

My code for validation is :

public void validate(Object target, Errors errors) {

    ValidationUtils.rejectIfEmptyOrWhitespace(errors, "password",
            "required.password", "Field name is required.");

    ValidationUtils.rejectIfEmptyOrWhitespace(errors, "confirmPassword",
            "required.confirmPassword", "Field name is required.");

    NewUser cust = (NewUser) target;

    if (!(cust.getPassword().equals(cust.getConfirmPassword()))) {
        errors.rejectValue("password", "notmatch.password");
    }

}

My configuration xml is :

Answer 1

Make sure you have notmatch.password key in message_en_US.properties file like

notmatch.password = Inccorect password

and change the basename to

<beans:property name="basename"
            value="/WEB-INF/resources/message" />

Answer 2

Configure PropertyPlaceholder in your context:

<context:property-placeholder locations="classpath*:my.properties"/>
