Class	Description
Jdk13LumberjackLogger	Implementation of the `org.apache.commons.logging.Log` interface that wraps the standard JDK logging mechanisms that are available in SourceForge's Lumberjack for JDKs prior to 1.4.
Jdk14Logger	Implementation of the `org.apache.commons.logging.Log` interface that wraps the standard JDK logging mechanisms that were introduced in the Merlin release (JDK 1.4).
Log	A simple logging interface abstracting logging APIs.
Log4JLogger	Implementation of `Log` that maps directly to a Logger for log4J version 1.2.
LogConfigurationException	An exception that is thrown only if a suitable `LogFactory` or `Log` instance cannot be created by the corresponding factory methods.
LogFactory	Factory for creating `Log` instances, with discovery and configuration features similar to that employed by standard Java APIs such as JAXP.
LogFactoryImpl	Concrete subclass of `LogFactory` that implements the following algorithm to dynamically select a logging implementation class to instantiate a wrapper for: Use a factory configuration attribute named `org.apache.commons.logging.Log` to identify the requested implementation class. Use the `org.apache.commons.logging.Log` system property to identify the requested implementation class. If Log4J is available, return an instance of `org.apache.commons.logging.impl.Log4JLogger`. If JDK 1.4 or later is available, return an instance of `org.apache.commons.logging.impl.Jdk14Logger`. Otherwise, return an instance of `org.apache.commons.logging.impl.SimpleLog`.
LogSource	Deprecated. Use `LogFactory` instead - The default factory implementation performs exactly the same algorithm as this class did
NoOpLog	Trivial implementation of Log that throws away all messages.
ServletContextCleaner	This class is capable of receiving notifications about the undeployment of a webapp, and responds by ensuring that commons-logging releases all memory associated with the undeployed webapp.
SimpleLog	Simple implementation of Log that sends all enabled log messages, for all defined loggers, to System.err.
WeakHashtable	Implementation of `Hashtable` that uses `WeakReference`'s to hold its keys thus allowing them to be reclaimed by the garbage collector.
WeakHashtable.Entry	Entry implementation
WeakHashtable.Referenced	Wrapper giving correct symantics for equals and hashcode
WeakHashtable.WeakKey	WeakReference subclass that holds a hard reference to an associated `value` and also makes accessible the Referenced object holding it.
