My question is regard to SL4j vs Commons-logging. SL4j is also under Apache Licence then why its not used in Tomcat by default. Is SL4J a rival to Commons- logging. Which one is better. Though SL4j is not developed by Apache community, But it is approved by the Apache Software Foundation as compatible with Apache Software License.
