[Introduction] [Dependencies] [Release Info] [Committers] [Action Items]

1. INTRODUCTION

The commons-logging package provides a simple, component oriented interface (org.apache.commons.logging.Log) together with wrappers for logging systems. The user can choose at runtime which system they want to use. In addition, a small number of basic implementations are provided to allow users to use the package standalone.

commons-logging was heavily influenced by Avalon's Logkit and Log4J. The commons-logging abstraction is meant to minimixe the differences between the two, and to allow a developer to not tie himself to a particular logging implementation.

The package does :

Have an API which should be as simple to use as possible
Provide support for Avalon's Logkit
Provide support for JDK 1.4 logging
Provide support for Log4J
Provide support for Avalon-Framework's Logger
Provide support for LumberJack logger
Provide pluggable support for other logging APIs
Privide a simple System.out logger

Non-goals:

This package will not perform logging itself, except at the most basic level.
We do not seek to become a "standard" API.

2. DEPENDENCIES

The Logging component is dependent upon the following external components for compilation:

Java Development Kit (Version 1.2 or later)
Apache Logging Log4j (Optional, Version 1.2.6 or later)
Apache Avalon LogKit (Optional, Version 1.0.1 or later)
Apache Avalon Framework (Optional, Version 4.0 or later)
LumberJack
Java Development Kit (Version 1.4 or later) logging APIs (Optional)

Of course, the user must ensure that any logging systems that they wish to use are present in the classpath when they use this component.
