Class Log4JLogger

java.lang.Object
org.apache.commons.logging.impl.Log4JLogger
All Implemented Interfaces:
Serializable, Log
@Deprecated public class Log4JLogger extends Object implements Log, Serializable
Deprecated.
Scheduled for removal since version 1.x of Log4j has reached end-of-life.
Implements Log to map directly to a Logger for Apache Log4J version 1.2.

Initial configuration of the corresponding Logger instances should be done in the usual manner, as outlined in the Log4J documentation.

The reason this logger is distinct from the 1.3.0 logger is that in version 1.2 of Log4J:

  • class Logger takes Priority parameters not Level parameters.
  • class Level extends Priority
Log4j 1.3 is expected to change Level so it no longer extends Priority, which is a non-binary-compatible change. The class generated by compiling this code against Log4j 1.2 will therefore not run against Log4j 1.3.
