Log4j is an open source tool developed for putting log statements in your application.

Log4j has three main components:. Log4j defines a Logger class. An application can create multiple loggers, each with a unique name. In a typical usage of Log4j, an application creates a Logger instance for each application class that will emit log messages. Loggers exist in a namespace hierarchy and inherit behavior from their ancestors in the hierarchy.

Log4j defines appenders handlers to represent destinations for logging output. Multiple appenders can be defined. For example, an application might define an appender that sends log messages to standard out, and another appender that writes log messages to a file.

Individual loggers might be configured to write to zero or more appenders. One example usage would be to send all logging messages all levels to a log file, but only ERROR level messages to standard out. Log4j defines layouts to control the format of log messages. Each layout specifies a particular message format. A specific layout is associated with each appender. This lets you specify a different log message format for standard out than for file output, for example.

The default configuration file is log4j. It can be overridden by using the log4j. The following is an example of a log4j. To specify logging to a Log4j Logger , set the following system properties on the command line:. The highest priority is given to the system property org.
