You could create another validator, and inside that perform a stripping of
non-numeric characters (stripCommas), then
execute code similar to the existing "long range" validator like this:
/**
* Determines if a formatted numeric value is between a range as defined by
* the user-supplied variables: min and max
* <p>
* Note: The only formattting performed is stripping off any commas. If the
* resulting number does not convert to a Long, then validation will fail as
* well.
* </p>
* <p>
* Validation succeeds if:
* <ol>
* <li>The value in question is null.</li>
* <li>The parsed field value is within the user-supplied range.</li>
* </ol>
* </p>
* @return
* @param application
* @param request
* @param errors
* @param field
* @param va
* @param bean
*/
public static boolean validateFormattedLongRange(
Object bean,
ValidatorAction va,
Field field,
ActionMessages errors,
HttpServletRequest request,
ServletContext application)
{
System.out.println("*** validateFormattedLongRange (" +
field.getProperty() + ") - START");
boolean isValid = true;
String value = null;
value = ValidationUtils.evaluateBean(bean, field);
if (!GenericValidator.isBlankOrNull(value))
{
try
{
long minVal = Long.parseLong(field.getVarValue("min"));
long maxVal = Long.parseLong(field.getVarValue("max"));
// We don't want to do this unless we use map.put to show
tampered value
// value = value.replaceAll("[^-0123456789.]", "");
value = value.replaceAll("[,]", "");
long lngValue = Long.parseLong(value);
if ((lngValue > maxVal) || (lngValue < minVal))
{
errors.add(field.getKey(),
Resources.getActionMessage(request, va, field));
isValid = false;
}
}
catch (NumberFormatException nfex)
{
errors.add(field.getKey(),
Resources.getActionMessage(request, va, field));
isValid = false;
}
}
System.out.println("*** validateFormattedLongRange (" +
field.getProperty() + ") - END, returning " + isValid);
return isValid;
}
Define this validator in validator-rules.xml:
<validator name="fmtLongRange"
classname="view.struts.validator.StrutsValidationExtensions"
method="validateFormattedLongRange"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest,
javax.servlet.ServletContext"
msg="errors.fmtLongRange">
</validator>
Add a rule for a field:
<field property="water_usage" page="2" depends="fmtLongRange">
<arg0 name="required" key="Page_2.water_usage"/>
<arg0 name="fmtLongRange" key="Page_2.water_usage" />
<arg1 name="fmtLongRange" key="${var:min}" resource="false"/>
<arg2 name="fmtLongRange" key="999,999,999" resource="false"/>
<var><var-name>min</var-name><var-value>0</var-value></var>
<var><var-name>max</var-name><var-value>999999999</var-value></var>
</field>
Define the message in the resource file (errors.fmtLongRange):
errors.fmtLongRange={0} must be a valid whole number between {1} and {2}.
