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

Hi, Undertow is using jboss logger to log errors and my application is using slf4j/logback with logback.xml config file in the classpath with Undertow core http server embedded. I handles most exceptions in my own handlers but sometimes uncaught exceptions reaches Connectors class - executeRootHandler method which logs the error and return 500 response code. My first question: Is there a way to redirect the logs from Undertow to logback logs and controlled by logback.xml? I've found some discussions about replacing logger in WildFly but I am using embedded Undertow core only. Second question: When Connectors.executeRootHandler will be called? Is it called when you have the following line in your handler? if (exchange.isInIoThread()) { exchange.dispatch(this); return; } Is there any way we can by pass this so that I can handle uncaught exceptions in my ExceptionHandler in the handler chain? Thanks, Steve
