public abstract class ExceptionHandlerFactory extends Object implements FacesWrapper<ExceptionHandlerFactory>
ExceptionHandlerFactory
is a factory object that creates (if needed) and returns a new ExceptionHandler
instance.
There must be one ExceptionHandlerFactory
instance per web
application that is utilizing JavaServer Faces. This instance can be
acquired, in a portable manner, by calling:
ExceptionHandlerFactory factory = (ExceptionHandlerFactory)
FactoryFinder.getFactory(FactoryFinder.EXCEPTION_HANDLER_FACTORY);

in interface FacesWrapper<ExceptionHandlerFactory>
public abstract ExceptionHandler getExceptionHandler()
Create and return a A new
ExceptionHandler
instance. The implementation must return
an ExceptionHandler
instance suitable for the environment.
For example, in some cases it may be desirable for an
ExceptionHandler
to write error information
to the response instead of throwing exceptions as in the case of
Ajax applications.
