The below is the change: web.xml:

method:-- throw new DCException(); DCException.java: public class DCException extends FacesException{ public DCException() { } public String getMessage() { return "DC Exception occured - Message"; } public String toString(){ return "DC Exception occured"; } } But when I encounter an exception in the application, the request goes to DCException but it is not getting redirected to the error page. Instead I am getting the below Error and goes to the 505 error: SEVERE: DC Exception occured javax.faces.el.EvaluationException: DC Exception occured at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:98) at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:98) at javax.faces.component.UICommand.broadcast(UICommand.java:311) at javax.faces.component.UIViewRoot.broadcastEvents(UIViewRoot.java:790) at javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:1255) at com.sun.faces.lifecycle.InvokeApplicationPhase.execute(InvokeApplicationPhase.java:77) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:97) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:114) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:334) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:227) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:300) at weblogic.servlet.internal.TailFilter.doFilter(TailFilter.java:27) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:57) at weblogic.servlet.internal.RequestEvents

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. http://stackoverflow.com/questions/18410007/jsf-2-global-exception-handling-navigation-to-error-page-not-happening 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

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.

facelets. Most of the time it happens when the facelet tries to resolve some EL expression, needs to create some JSF managed bean, but one or more required URL parameters are either missing or have invalid values. In a development environment, it makes sense to show this page because the various pieces of contextual information (full stack trace + JSF component tree + variables in scope) provide plenty of clues with which to diagnose the issue. However, when you ship a product to a customer or push your changes to a production environment, it would be nice to change the behavior and provide a pleasant error page to the user. Fortunately, the facelets framework makes overriding this default behavior incredibly simple. The basic premise is to redirect to a custom error page so you can provide a layout that hides the unappealing stack trace, but which still provides a link to view those details (primarily so your customers can report the bugs back to you). Note: the following code examples will be pulled directly from the RHQ / Jopr code base. The first step is to add a custom view handler to your web application. Open up the faces-config.xml file and add a custom view handler:
