I am trying to implement a global exception handler which will redirect the fullajaxexceptionhandler user to a generic error page whenever any exception occurs (e.g. NullPointerException,ServletException,ViewExpiredException etc.) 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 com.common.exceptions.CustomExceptionHandlerFactory My CustomNavHandler public class CustomExceptionHandler extends ExceptionHandlerWrapper { private static final Logger logger = Logger.getLogger("com.gbdreports.common.exception.CustomExceptionHandler"); private final ExceptionHandler wrapped; public CustomExceptionHandler(ExceptionHandler wrapped) { this.wrapped = wrapped; } @Override public ExceptionHandler getWrapped() { return this.wrapped; } 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 FacesContext fc = FacesContext.getCurrentInstance(); final ExternalContext externalContext = fc.getExternalContext(); final Map requestMap = fc.getExternalContext().get

This bean method returns a string to perform a redirect, like this "/licenseGenerated.xhtml?faces-redirect=true" This method is supposed to do several back-end calls based on the user's input. Now, this means that in http://stackoverflow.com/questions/18338910/error-handling-between-button-and-bean-method I have to add some error handling. Here's the behavior I need. The user accesses the application and is in the main.xhtml page. The user inputs the value and clicks the button. If the whole procedure works correctly, then the user should be redirected to the /licenseGenerated.xhtml page. Otherwise, in case an error happened, I don't need a redirect. What I need is to render a jsf component that contains an error message on the main.xhtml page. So, what should the generateLicense method return in case of an error, and what would the button's jsf code be like? Thanks for the help! -EDIT- The error would be detected during the bean's method execution. This is based on a response from a rest service. Simply said, there are two possible outcomes from the service. A 200 (OK), in which case, the redirect is needed, or a 400 (NOT FOUND) in case the user's input is wrong. So, the java method would look like this: public String generateLicenseFile(){ String response = ""; ... // all the back-end computations if(response == "200"){ return "/licenseGenerated.xhtml?faces-redirect=true

You probably don't want your users to see that message in such that ugly way. To substitute a better error page, use error-page tag jsf error page in 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.
