Tomcat Logging With Slf4j and Log4j

Question

I\'ve got a web-app deployed to a Tomcat 7 server. My application uses log4j and a file appender. However, not all logging messages

Answer 1

It looks like the StateUtils class is using java.util.logging (jul). It stands to reason that other myfaces classes also use jul. Thus, you would probably want to funnel jul logs through SLF4J. Have a look at bridging legacy APIs, in particular the jul-to-slf4j bridge.

Please see SLF4JBridgeHandler javadocs for usage instructions when installing jul-to-slf4j.

Answer 2

try including the jcl-over-slf4j as a dependency. myfaces is probably using commons-logging.

check the slf4j docs: http://www.slf4j.org/legacy.html#jcl-over-slf4j

Answer 3

Configure your tomcat server according to the steps described at http://adfinmunich.blogspot.de/2012/03/how-to-configure-tomcat-to-use-slf4j.html. This blog entry describes how to replace java.util.logging by slf4j (using log4j behind the facade).
