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.
