Apache Commons Logging is a logging facade for the Java programming language.

Apache Commons Logging is a component of the Apache Commons project. Apache Commons Logging is a logging facade, is open source software distributed under the Apache License, Version 2.0, and provides a common API for use with several logging implementations, including log4j and Java Logging.

This logging facade allows the logging implementation to be chosen at runtime yet allows all logging development to be done against a single API.
