Class LogWrapper

java.lang.Object
  org.apache.commons.ssl.LogWrapper

public class LogWrapper

extends java.lang.Object

LogWrapper can be used for situations where log4j might not be available on the classpath. It presents the most basic and critical components of the log4j API, and passes all log calls through to log4j if possible. If log4j is not available, logging is sent to standard-out by default.

This default logging to standard-out (which only occurs if log4j is NOT available) can be disabled or changed via the static setBackupStream() and setBackupLogFile() methods.
