The complete manual describes the log4j API in considerable detail, including its features and design rationale. Authored by Ceki Gülcü, one of log4j's key contributors, the manual is intended for developers already familiar with the Java language but new to log4j, as much as for experienced log4j users. With the aid of introductory material and many examples, new users should quickly come up to speed. Seasoned log4j users will also find fresh material not discussed anywhere else. Advanced topics are also covered in detail so that the reader can harness the full power of log4j.
