[logback-user] Logback for Jetty HTTP logs and Java application logs

Is it possible to use one instance of logback for logging Jetty request logs and Java logs? Jetty is embedded, so when I configure 2 instances, I got a warning: ` Class path contains multiple SLF4J bindings`. For Java Logs, I get logger from Logger factory. In case of Jetty logs, I configure RequestLogHandler . How to configure one instance? How can I separate HTTP request and Java logs? Many thanks for help. Best Regards, Tigran.
