Subject RE: Question about throwing an exception in the ValidatorForm validate method.
Date Fri, 09 Apr 2004 19:45:53 GMT
The RequestProcessor  processPreprocess(request, response) method seems the
best but
 I'm not sure how to override it for my first login page where the valid
session is not set up yet.
Can I give a specific requestProcessor for an individual action mapping?

Thanks for the first response Niall.

validate method.

Do you want to do this on a form by form basis or for all forms?

If you want to do it for all forms then you could either customise
RequestProcessor (maybe in the processPreprocess(request, response) method)
or use a Filter.

If you need to do it on a form by form basis, then why not skip validation
if its expired and let the Action check your session and throw the
Exception.
