Simple Logging Facade for Java (SLF4J) is an abstraction of different logging frameworks (eg. log4j, java.util.logging, commons logging etc.). This tutorial describes how to configure SLF4J with log4j as underlying logging framework. To use SLF4J, it is required to include 3 jars SLF4J API (slf4j-api-x.x.x.jar)
Simple Logging Facade for Java (SLF4J) is an abstraction of different logging frameworks (eg. log4j, java.util.logging, commons logging etc.). This gives the developer an opportunity to plug-in desired logging framework at deployment time without changing the code. To use SLF4J, it is required to include 3 jars SLF4J
