I have a FormBean derived from ValidatorActionForm. I define validation

No I like to add some additional validations which depend on user input.
I thought, I can handle this in the validate(..) method but it gets
never called!
I implemented something like:
public class QueryTripsForm extends ValidatorActionForm
{
...
public ActionErrors validate(ActionMapping mapping,
javax.servlet.ServletRequest request)
{
ActionErrors e = null;
super.validate(mapping, request);
// doing some special checks here
// ......
return e;
}
....
}
That looks OK. Are you sure you want to extend ValidatorActionForm
rather than just ValidatorForm? The effect is subtly different. You
haven't posted your validation config, so I can't tell which would be
correct for your useage.
Why is this validate method never called? (validate is set to true, see
below)
<action
input="/form/queryTrips.jsp"
name="queryTripsForm"
path="/listTrips"
scope="request"
validate="true"
type="ch.smartsol.struts.action.ListTripsAction">
<forward name="Success" path="/template/ShowTripsResult.jsp" />
</action>
How is the form declared in struts-config.xml? What URL are you
accessing? Assuming your form is declared with the name 'queryTripsForm'
and you're actually hitting this action mapping, validate() should be
getting called I think.
Is there any way to combile 'default' validations defined in
validation.xml with additional validations implemented in the validate()
method??
Yes, with a slight correction to your code above:
ActionErrors e = super.validate(mapping, request);
You need to capture the errors from the 'default' validation process or
they'll be discarded.
