Org.apache.commons.logging Jar File

The Logging Component When writing a library it is very useful to log information. However there are many logging implementations out there, and a library cannot impose the use of a particular one on the overall application that the library is a part of. The Logging package is an ultra-thin bridge between different logging implementations. A library that uses the commons-logging API can be used with any logging implementation at runtime. Commons-logging comes with support for a number of popular logging implementations, and writing adapters for others is a reasonably simple task. Applications (rather than libraries) may also choose to use commons-logging.

This may be obvious, but I have been looking for a simple example of using org.apache.commons.logging to log to a specific file (i.e. /path/to/my-log.txt) public. Look for a configuration attribute of this factory named org.apache.commons.logging.Log. Iomega Screenplay Codec on this page. The commons-logging.jar file includes the JCL API. Apache-commons/apache-commons.jar.zip( 742 k) The download jar file contains the. UnmodifiableSortedSet.class org.apache.commons.logging.Log.class org.apache.

While logging-implementation independence is not as important for applications as it is for libraries, using commons-logging does allow the application to change to a different logging implementation without recompiling code. Note that commons-logging does not attempt to initialise or terminate the underlying logging implementation that is used at runtime; that is the responsibility of the application. However many popular logging implementations do automatically initialise themselves; in this case an application may be able to avoid containing any code that is specific to the logging implementation used.
