x4juli is a port of the main parts of log4j to the
J2SE Logging API. The default implementation is
incomplete and therefore still not widely used,
even when introduced in J2SE 1.4. x4juli provides
logmanagers, formatters, handlers, and filters to
fill the gap. The interface and use of the
original API has not been changed. Additionally,
x4juli delivers a native implementation of the
Jakarta Commons Logging (JCL) API and the Simple
Logging Facade for Java (SLF4J) API.
