Subject: Newbie question: how does MyAction class handle Exceptions?
Hi,
I have DataAccessException thrown by DAO class and catched by
BusinessDeligate class. ApplicationException thrown by BusinessDeligate
class and catched by MyAction class. I want to send a jsp to clients to
display a message that the clients submit a duplicate entry in their
request. What should I do for this?
Thanx.
Leon

Put an informative message in the DAO code that constructs the SQLException.
Some people then generate an email from the exception message and send
it to the administrator email account. Other people might do something
more technical such as send a JMS message that there is a problem. Or
even open a socket and fire a simple XML message to some web service
containing the contents of the exception. These ideas require you to
have established a facility to receive and store such messages (JMS or
web service), and might not be worth the added complexity.
Other people don't care if the user sees the exception message and they
just print a message like "Please copy the contents of this stack trace
into an email and send it to the admin". This is the easy, if ugly,
solution.

I should forward an ApplicationException to MyAction class and then,
MyAction finds an appropriate jsp based on the message in
ApplicationException. But, how can I know the SQLException thrown by
persistance tire is duplicate entery SQLException or other SQLException?
Thanks.
