I am trying to implement a global exception handler which will redirect the user to a generic error page whenever any exception occurs (e.g. NullPointerException,ServletException,ViewExpiredException etc.) http://stackoverflow.com/questions/18410007/jsf-2-global-exception-handling-navigation-to-error-page-not-happening Whenever a NPE occurs in my app, My customnavhandler breakpoint is hit and NavigationHandler code is executed, but somehow redirection to error page is not happening, the requested page remains partially rendered. Any idea what could be wrong here ? One info is that I am throwing an NPE deliberately on the requested page (which was partiallyu rendered after NPE) My faces-config.xml entry Orchestra ExtVal Portlet Bridge Test https://myfaces.apache.org/wiki/core/user-guide/jsf-and-myfaces-howtos/managing-errors---infos---warnings/handling-server-errors.html Commons Ext-Scripting Sandbox Others Project Documentation Documentation Index JSF Intro Quick Start Getting Started FAQ Confluence Wiki Public https://wmarkito.wordpress.com/2012/04/05/adding-global-exception-handling-using-jsf-2-x-exceptionhandler/ Wiki Compatibility Continuous Integration Issue Tracking Mailing Lists Project License Project Summary Project Team Source Repository About Foundation error page ASF Sponsorship Thanks Security License Home»Wiki»MyFaces Core»MyFaces Core User Guide»JSF and MyFaces Howtos»Managing Errors - Infos - Warnings Handling Server Errors Error handling for MyFaces Core 2.0 and later versions Since JSF 2.0, it is possible jsf exception handling to provide a custom javax.faces.context.ExceptionHandler or javax.faces.context.ExceptionHandlerWrapper implementation to deal with exceptions. To do that, just create your custom class, an factory that wrap/override it and add the following into your faces-config.xml: faces-config.xml 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 IteratorJsf Custom Error Page
