Exception Handling

I have two beans. One that handles (a) database connections
(singleton), and the other that (b) handles the database interactions.
(b) also has a public method that is published as a web service.
My question is: how do I handle exceptions within the beans for example
(a) just throws its
SQLExceptions to the calling (b). In bean(b) do I just catch the
exception and logit or do I throw it to the container?

thx jason

Hi Jason,

Why don't you use container managed persistence or hibernate persistence
framework for this?

It depends on your exception. If it's an application critical exception
and if you use a web frontend throw it to the container and configure
error pages in your web.xml to show appropriate messages.

If you use for example a Swing client, the client have to handle these
exceptions.

Hope it helps.
