How can I catch a

com.sun.faces.context.FacesFileNotFoundException

in a Java EE web application?

I tried it with adding the following lines in my web.xml file but I was not successful:

  ...
  <error-page>
    <error-code>404</error-code>
    <location>/404.jsf</location>
  </error-page>
  <error-page>
    <error-code>500</error-code>
    <location>/404.jsf</location>
  </error-page>
  <error-page>
    <exception-type>FacesFileNotFoundException</exception-type>
    <location>/404.jsf</location>
  </error-page>

    You need to specify the FQN (Full Qualified Name), not just the N as exception type.

    <exception-type>com.sun.faces.context.FacesFileNotFoundException</exception-type>

    Alternatively, if you already happen to use OmniFaces, register its FacesExceptionFilter and then the FacesFileNotFoundException will be handled as 404.
