Log4JLogger

public class Log4JLogger implements Log,Serializable(Code)

Implementation of Log that maps directly to a Logger for 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 logger is that in version 1.2 of Log4J:

class Logger takes Priority parameters not Level parameters.
class Level extends Priority

Log4J1.3 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.
