Heres a method that I use to validate that one date entered by the user is
earlier than another.
public static boolean validateDateBefore( Object bean, ValidatorAction
va,
Field field, ActionErrors
errors,
HttpServletRequest
request )
{
// verify that the bean contains a valid date in the specified
'field'
Date targetDate = StrutsValidator.validateDate( bean, va, field,
errors, request );
if( targetDate == null )
return false;
// get the date to compare to
String later = field.getVarValue( "dateBefore" );
if( GenericValidator.isBlankOrNull( later ) )
{
errors.add( field.getKey(),
StrutsValidatorUtil.getActionError(request, va, field) );
return false;
}
String lDate = ValidatorUtil.getValueAsString( bean, later );
Date laterDate = StrutsValidator.validateDate( lDate, va, field,
errors, request );
if( lDate == null )
return false;
// now we can compare the 2 dates
if( ! isDateAfter( laterDate, targetDate ) )
{
StringBuffer buffer = new StringBuffer( field.getProperty() );
buffer.append( " must be earlier than " ).append( lDate );
errors.add( field.getKey(),
StrutsValidatorUtil.getActionError(request, va, field) );
return false;
}
return true;
}
And this is the entry from validation.xml
<field property="auditDate"
depends="date, dateBefore">
<msg name="date"
key="Please enter a valid date, if any, that the audit will be done."
resource ="false"/>
<msg name="dateBefore"
key="Audit date must occur before the final date."
resource="false"/>
<var>
<var-name>dateBefore</var-name>
<var-value>finalDate</var-value>
</var>
</field>
The finalDate referenced by var-value is another attribute of my
ValidatorForm.
Does this help?
