Using Log4J for logging<\/p>\n

\"log4j\"<\/a><\/p>\n

Apache log4j is a Java-based logging framework that provides runtime application feedback. It provides the ability to control the granularity of log statements using an external configuration file (log4j.properties).<\/p>\n

The log4j utility has three main components: loggers, appenders, and layouts. Loggers are logical log file names. They are the names known to the Java application. Each logger is independently configurable for the level of logging. Outputs are controlled by Appenders. Numerous Appenders are available and multiple Appenders can be attached to any Logger. This makes it possible to log the same information to multiple outputs. Appenders use Layouts to format log entries.<\/p>\n
