How about catching the database exception in the middle
tier and throwing a more middle tier like Exception (so
your front tier - any of the struts classes - don't have
to deal with anything with SQL in it) that you define like
UserExistsException or InvalidSomethingException or
ThisHappenedException and then in the struts config have
<global-exceptions>
<exception
key="errors.user.exists"
type="my.exception.UserExistsException"
path="doc.explainUserError" //If you were using tiles defs
//or the JSP name otherwise
/>
</global-exceptions>
I like keeping the try catches out of my Action class.

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.
