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.
