Log4j to JUL Adapter

The Log4j 2 to JUL Adapter allows applications coded to the Log4j 2 API to be routed to java.util.logging (JUL).

Use of this adapter may cause some loss of performance as the Log4j 2 Messages must be formatted before they can be passed to JUL. With Log4j 2 as the implementation these would normally be formatted only when they are accessed by a Filter or Appender.

Requirements

The Log4j 2 to JUL adapter is dependent on the Log4j 2 API.

Usage

Include this JAR. Configure JUL as usual.

Use of the JUL adapter (log4j-to-jul-2.x.jar) together with the JUL bridge (log4j-jul-2.x.jar) should never be attempted as it will cause events to endlessly be routed between SLF4J and JUL.
