CDI - handling errors

Question

I am migrating my Seam 2 powered application to CDI and one of the things that is critical for me to retain is the error handling. In Seam 2, I simply replaced the default exception handler with my own, but in CDI, I am guessing I'll have to use an Interceptor.

How would I set this up as using an Interceptor requires me to specify where it will intercept calls? I mostly want to accomplish auditing, so when an exception occurs, it is logged, then a notification (email, xmpp, sms, phone call) is sent out to administrators.

When an exception occurs, is there simply an event that I can listen for and act on?

Answer 1

Are you using JSF2? If yes, instead of writing an Interceptor, you could register an ExceptionHandlerFactory in your web.xml as described here. In a CustomExceptionHandler, you can catch all Exceptions and handle them programmatically. I'm using this approach in my JEE6-CDI-app, find it quite okay.
