'ExceptionHandlerFactory was not configured properly' on Glassfish 3.1.2.2
I'm trying to handle uncaught exceptions through ExceptionHandler. Following the code in JSF2 complete reference, I've created the classes for my handler. But when I deploy my app, it throws the next stackTrace:
SEVERE: Critical error during deployment:
com.sun.faces.config.ConfigurationException: Factory 'javax.faces.context.ExceptionHandlerFactory' was not configured properly.

This is my faces-config.xml:
<factory>
<exception-handler-factory>
exception.ExceptionHandlerFactory
</exception-handler-factory>
</factory>
ExceptionHandlerFactory.java
public class ExceptionHandlerFactory extends javax.faces.context.ExceptionHandlerFactory {
private transient Logger logger = Logger.getLogger(this.getClass().getName());
private ExceptionHandlerFactory parent;
public ExceptionHandlerFactory(ExceptionHandlerFactory parent) {
this.parent = parent;
}
@Override
public ExceptionHandler getExceptionHandler() {
ExceptionHandler result = parent.getExceptionHandler();
result = new CustomExceptionHandler(result);
return result;
}
}
CustomExceptionHandler.java
public class CustomExceptionHandler extends ExceptionHandlerWrapper {
private ExceptionHandler parent;
public CustomExceptionHandler(ExceptionHandler parent) {
this.parent = parent;
}
@Override
public ExceptionHandler getWrapped() {
return this.parent;
}
@Override
public void handle() throws FacesException {
for (Iterator<ExceptionQueuedEvent> i =
getUnhandledExceptionQueuedEvents().iterator();
i.hasNext();) {
ExceptionQueuedEvent event = i.next();
ExceptionQueuedEventContext context =
(ExceptionQueuedEventContext) event.getSource();
Throwable t = context.getException();
if (t instanceof ViewExpiredException) {
ViewExpiredException vee = (ViewExpiredException) t;
FacesContext fc = FacesContext.getCurrentInstance();
NavigationHandler nav =
fc.getApplication().getNavigationHandler();
try {
fc.getExternalContext().
getFlash().put("currentViewId",
vee.getViewId());
nav.handleNavigation(fc, null, "/login?faces-redirect=true");
fc.renderResponse();
} finally {
i.remove();
}
}
}
getWrapped().handle();
}
}
Server is Glassfish 3.1.2.2.
I need to to some logic when I get the ViewExpiredException. Did I miss something? Thanks in advance !!!!
EDIT:
As @BalusC pointed, I changed my factory class name, so this is my CustomExceptionHandlerFactory.java:
public class CustomExceptionHandlerFactory extends ExceptionHandlerFactory {
private ExceptionHandlerFactory parent;
public CustomExceptionHandlerFactory(ExceptionHandlerFactory parent) {
this.parent = parent;
}
@Override
public ExceptionHandler getExceptionHandler() {
ExceptionHandler result = parent.getExceptionHandler();
result = new CustomExceptionHandler(result);
return result;
}
}
and my faces-config.xml:
<factory>
<exception-handler-factory>
com.exception.CustomExceptionHandlerFactory
</exception-handler-factory>
</factory>
I hope this could be helpful for anyone with this silly problem.
Answer
Your mistake is that you reused the same classname as an existing API class for some unclear reason and got them mixed up in the code.
The parent constructor argument (and local variable) has to be of type javax.faces.context.ExceptionHandlerFactory, not of your exception.ExceptionHandlerFactory. This wrong type caused that JSF was unable to invoke the constructor and hence the -rather self explaining- InstantiationException (it couldn't be instantiated).
Better rename your class to something unique like CustomExceptionHandlerFactory.
