Pro Apache Log4j 2ND Edition

Application logging refers to the means to indicate the state of a software application at runtime and is most useful in the debugging process of software writing. In this work, Gupta (a UK-based Java/J2EE consultant) explains the process of application logging using the Java-based Apache log4j (version 1.2.9), an open-source logging application programming interface (API). Chapters cover the basics of the API; formatting logging information; filtering, error handling, and special rendering of log messages; creating custom logging components; using log4j in Java 2 Enterprise Edition, and using the Apache log tag library.
