LogFactory
instead - The default factory
implementation performs exactly the same algorithm as this class didpublic class LogSource extends Object
Factory for creating Log
instances. Applications should call
the makeNewLogInstance()
method to instantiate new instances
of the configured Log
implementation class.
By default, calling getInstance()
will use the following
algorithm:
org.apache.commons.logging.impl.Log4JLogger
.org.apache.commons.logging.impl.Jdk14Logger
.org.apache.commons.logging.impl.NoOpLog
.You can change the default behavior in one of two ways:
org.apache.commons.logging.log
to the name of the
org.apache.commons.logging.Log
implementation class
you want to use.LogSource.setLogImplementation()

public static void setLogImplementation(Class logclass) throws LinkageError, ExceptionInInitializerError, NoSuchMethodException, SecurityException
public static Log makeNewLogInstance(String name)
Log
implementation, based
on the given name.
The specific Log
implementation returned
is determined by the value of the
org.apache.commons.logging.log property.
The value of org.apache.commons.logging.log may be set to
the fully specified name of a class that implements
the Log
interface. This class must also
have a public constructor that takes a single
String
argument (containing the name
of the Log
to be constructed.
When org.apache.commons.logging.log is not set,
or when no corresponding class can be found,
this method will return a Log4JLogger
if the log4j Logger class is
available in the LogSource
's classpath, or a
Jdk14Logger if we are on a JDK 1.4 or later system, or
NoOpLog if neither of the above conditions is true.
