org.omnifaces.filter
Class FacesExceptionFilter

java.lang.Object
  org.omnifaces.filter.HttpFilter
      org.omnifaces.filter.FacesExceptionFilter

All Implemented Interfaces:

javax.servlet.Filter

public class FacesExceptionFilter
extends HttpFilter

This filter will solve 2 problems with exceptions thrown in JSF methods.

1. Mojarra's FacesFileNotFoundException needs to be interpreted as 404.
2. Root cause needs to be unwrapped from FacesException (Mojarra) and ELException (MyFaces) to utilize standard Servlet API error page handling.

To get it to run, map this filter on the <servlet-name> of the FacesServlet.

 <filter>
   <filter-name>facesExceptionFilter</filter-name>
   <filter-class>org.omnifaces.filter.FacesExceptionFilter</filter-class>
 </filter>
 <filter-mapping>
   <filter-name>facesExceptionFilter</filter-name>
   <servlet-name>facesServlet</servlet-name>
 </filter-mapping>
