My first approach would be to see how Tapestry already does it. In
TapestryModule there is a RequestFilter configured:

        configuration.addInstance("ErrorFilter", RequestErrorFilter.class);

One approach would be to add your own filter to catch your apps
exceptions so you can choose which go to the standard error page and
which go to your other error page.

The RequestErrorFilter uses services to do it's job so you could
alternatively provide your own implementation.
