Re: [undertow-dev] Undertow jboss logging redirect to logback log file and console

I think this is something I should address in Undertow Core (Servlet already has io.undertow.servlet.api.ExceptionHandler), to allow you to register a handler that will be called if an exception propagates outside of the handler chain. I think there are two options: 1) HttpServerExchange.setExceptionHandler(HttpHandler handler), and then make the exception available as an attachment on the Exchange. 2) HttpServerExchange.setExceptionHandler(ExceptionHandler handler), where ExceptionHandler has a single method that takes the exchange and the exception. Thoughts? Stuart
