Class LogUtil

java.lang.Object

com.bigdata.util.config.LogUtil

public class LogUtil
extends Object

Utility class that provides a set of static convenience methods related to the initialization and configuration of the logging mechanism(s) employed by the components of the system. The methods of this class can be useful both in Jini configuration files, as well as in the system components themselves.

This class relies on the presence of either the log4j.configuration or the log4j.primary.configuration property.

If neither of those properties is found, then this class searches the CLASSPATH for a log4j configuration. While this is a change from the historical, searching the CLASSPATH is necessary for webapp deployments.

This class understands files with any of the following extensions { .properties, .logging, .xml . If neither configuration property is defined, if the resource identified by the property can not be located, or if a log4j configuration resource can not be located in the default location along the class path then this class will will a message on stderr.

A watcher is setup on the log4j configuration if one is found.

This class cannot be instantiated.
