Interface ExceptionPresenter

All Known Implementing Classes:

ExceptionPresenterImpl, PortletExceptionPresenter

public interface ExceptionPresenter

Invoked by the IEngine if there's an uncaught exception (checked or runtime) processing a request. The ExceptionPresenter is responsible for presenting a exception message (or description) to the user. The default implementation activates the "Exception" page, but it is common to override this to do something application specific (typically, return to the Home page and display an error message there). This service also provides a good hook for creating a server-side log of exceptions.
