Logging package
This package contains classes that provide the OJB logging API.
The Logger interface defines the behaviour of the
OJB logging mechanism. This API corresponds closely to the LOG4J Category Api.
By using this interface for logging operations OJB remains free from
Logger-Implementation specific code.
The class PoorMansLoggerImpl implements Logger and
provides the OJB default implementations. All logging output is directed to
System.out.
The class Log4jLoggerImpl implements Logger and
provides LOG4J based logger implementations.
The factory class LoggerFactory can be used to create
Logger instances.
The Logger-implementation class served by the factory is
configured by settings in the OJB.properties file.
Patterns applied:
Configurable Factory, Adapter
Todo:
Provide a JDK1.4 based logger
