First off, thank you for your responses, I've worked on this a little
more and am still have problems getting the error message pages to even
appear when the server side error is generated. Below is my web.xml
<!-- Use Documents saved as *.xhtml for Facelets-->
<context-param>
<param-name>javax.faces.DEFAULT_SUFFIX</param-name>
<param-value>.xhtml</param-value>
</context-param>
<context-param>
<param-name>facelets.VIEW_MAPPINGS</param-name>
<param-value>*.xhtml</param-value>
</context-param>
....
<!-- Error configuration -->
<error-page>
<error-code>404</error-code>
<location>/error_pages/404.xhtml</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/error_pages/500.xhtml</location>
</error-page>
Please let me know if I missed anything relevant.
Currently when an error (500) is generated all I get is a blank white
screen :(. I can go directly to the error pages both logged into the
system and not and I get the nice little "Something has gone wrong .."
custom error page that I've setup for this test...
Any ideas?

Rob,
First you need to gather the information about the exception, then send
it to who needs to know. You might want to be proactive and send it to
the support team regardless of what the users want...
One thing to lookout for is that depending on where you exception is
thrown the implicit "exception" variable may not be the one you're
looking for and you have to "unwind" the calling stack to find the root
cause. That's what Tomcat's default error page does. I found it
instructive to study the source of the ErrorReportValve in subversion:
<http://svn.apache.org/repos/asf/tomcat/tc6.0.x/trunk/java/org/apache/ca
talina/valves/ErrorReportValve.java>
Look into the "report" method to see how to use "exception.getCause()"
to get to the root cause.
I hope you find this useful.
