unwrap from JSF exception

[Joshua Antony]

I am working on an application that uses JSF in the front end and Spring as service layer.

We have defined 2 types of exception called as ApplicationException and SystemException

Any exception will be wrapped within above exceptions and thrown to the client.

We need to show different error pages for the above 2 exceptions.

We tried using <error-page> in web.xml but it does not work, since our application is wrapped within FacesException and thrown.

What may be the workaround for this?

Regards,
Joshua
