the web.xml file, in that you can specify either a Java Exception or an HTTP error code. So in case the type of thrown exception has matched that type mentioned in the web.xml exception-type or the error code that generated by the server has matched error-code that mentioned in the web.xml, the JSF framework will handle it by forwarding the user into the desired view that you've defined for such those errors or exceptions. 1.

April 5, 2012April 6, 2012 470 Words Adding global exception handling using JSF 2.x ExceptionHandler This a great feature of JSF 2.x: A generic API to manipulate application exception in a global manner. In order to implement this you must implement (extend) two different classes: ExceptionHandlerWrapper - Provides a simple implementation of ExceptionHandler that can be subclassed by developers wishing to provide specialized behavior to an existing ExceptionHandler instance. The default implementation of all methods is to call through to the wrapped ExceptionHandler instance. ExceptionHandlerFactory - A factory object that creates (if needed) and returns a new ExceptionHandler instance. On Duke's Forest this is the implementation: CustomExceptionHandlerFactory.java: package com.forest.exception; public class CustomExceptionHandlerFactory extends ExceptionHandlerFactory { private ExceptionHandlerFactory parent; // this injection handles jsf public CustomExceptionHandlerFactory(ExceptionHandlerFactory parent) { this.parent = parent; } @Override public ExceptionHandler getExceptionHandler() { ExceptionHandler handler = new CustomExceptionHandler(parent.getExceptionHandler()); return handler; } } CustomExceptionHandlerFactory.java: package com.forest.exception; public class CustomExceptionHandler extends ExceptionHandlerWrapper { private static final Logger log = Logger.getLogger(CustomExceptionHandler.class.getCanonicalName()); private ExceptionHandler wrapped; CustomExceptionHandler(ExceptionHandler exception) { this.wrapped = exception; } @Override public ExceptionHandler getWrapped() { return wrapped; } @Override public void handle() throws FacesException { final Iterator i = getUnhandledExceptionQueuedEvents().iterator(); while (i.hasNext()) { ExceptionQueuedEvent event = i.next(); ExceptionQueuedEventContext context = (ExceptionQueuedEventContext) event.getSource(); // get the exception from context Throwable t = context.getException(); final FacesCont
