Hi Rajesh,
I've made some changes to ValidationException and
submitted them to Castor for review on Jan. 15 and
described these changes in great detail on Jan. 3 (you
can look up these e-mails in the archive if you're
interested).
I'm still waiting to see if these changes will be
accepted by Castor or not but I think my changes may
be useful to you.
I've basically added 4 instance variables (field name,
field value, error type and value restriction) to
ValidationException and populated them in the
constructors upon every instantiation of
ValidationException due to bad user input rather than
anything else such as bad schema definition.
In your case, I think field name would be "billing
name" and the field value "Bill2003".
These changes were intended to do the following:
. consistently return the field name in the
exception;
. create a mechanism to allow multilingual support
for error messages;
. allow the Business to easily use their own
wording
of error messages on a per field basis instead of the
default English messages
I can send you the .jar of my changes if you are
interested.
Regards,
Joyce
