I appreciate your help.
I gave up on Valang. I don't think it works.
Here is what I did for others using Spring MVC:
Created a new class which implemented Validator with the following validate
method:
public void validate(Object target, Errors errors) {
KeyMetadata givenData = (KeyMetadata)target;
if (givenData == null) {
errors.reject("errors.nullpointer", "Null data received");
} else {
Date endDate = givenData.getEndDate();
Date startDate = givenData.getStartDate();
if (endDate != null && endDate.before(startDate) ||
endDate != null && endDate.equals(startDate)) {
errors.rejectValue("endDate", "errors.invalidEndDate",
"The End Date cannot be before or equal to the start
date.");
}
}
}
Then I added this validator to applicationContext-validation.xml as a <bean>
definition.
Then I added the reference to the list of validators for the
specific FormController that I wanted to validate on in
dispatcher-servlet.xml.
<property name="validators">
<list>
<ref bean="beanValidator"/> <!--Commons Server-side
validation -->
<ref bean="keyMetadataValidator"/> <!--endDate
validator -->
</list>
</property>
