Class JetspeedLogger

java.lang.Object
  org.apache.jetspeed.services.logging.JetspeedLogger

public class JetspeedLogger

extends java.lang.Object

The implementation of loggers for Jetspeed. This class acts as a wrapper so that the underlying logging implementation is hidden fromthe rest of Jetspeed The current implementation uses Log4J.
