A new example should be done and the current one retired. Here's the email thread talking about an idea between myself and Dan Allen:

From Jason:

Since we're being asked for examples to give to QE and Jozef has
integrated catch into his module (and has some tests for it, and also
asked me to remove the jaxrs example) I'm not quite sure what to do
for a new example that wouldn't confuse because because Rest, Faces
and Servlet all have Catch integrations. I could do one for wicket,
but once wicket has an integration I'd need to retire that one as
well. Do you have any ideas?

From Dan:
I would go with simple and easy In your case, the example is going to be about show-and-tell more than test coverage. My suggestion would be to create an index page with a couple buttons.

Catch error and:
Show pretty error
Redirect to page
Log error and ignore
You can just base the examples on a failing Servlet. You could also include an example of throwing an exception to Catch explicitly (instead of waiting for it to bubble from Servlet). But again, keep it simple.

Just give the user a feel for what they can do. Make sure you have the simplest possible example in there, so that they can see the big picture. Then, add others that are fancier as you see fit.
