I need to customize the “Not found in ExternalContext as a Resource” page. I have tried both changing the web.xml to add the 404 and 500 error-code sections:
<error-page>
<error-code>500</error-code>
<location>/500.xhtml</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>/404.xhtml</location>
</error-page>
and following the info provided by SO/forums/blog like
http://duckranger.com/2010/08/configure-a-custom-404-page-in-glassfish/
How to create custom 404 messages in JSF 2.0?
but no success:
All I get is a blank page (or a “This XML file does not appear to have any style information associated with it. The document tree is shown below.” that the browser generates) and the following stack trace when accessing a non-existing page:
SEVERE: doFilter

EDIT and FIX
In some blog/forum, the Filter chaining examples are as follows:
try {
chain.doFilter(request, response);
} catch (Throwable t) { // or Exception
// do some logging
}
This is wrong and prevents JSF to continue the normal flow of error processing. I kept the logging but re-throw the Exception. After that the error-code 500 in web.xml takes care of the issue.
try {
chain.doFilter(request, response);
} catch (Throwable t) { // or Exception
// do some logging
throw t; // so JSF/Container can continue normal low of error handling
}
In some blog/forum, the Filter chaining examples I had blindly copied are as follows:
