Class Log4jLoggerImpl

java.lang.Object

org.apache.ojb.broker.util.logging.Log4jLoggerImpl

All Implemented Interfaces:

java.io.Serializable, org.apache.ojb.broker.util.configuration.Configurable, Logger

public class Log4jLoggerImpl
extends java.lang.Object
implements Logger

This is a Logger implementation based on Log4j. It can be enabled by putting LoggerClass=org.apache.ojb.broker.util.logging.Log4jLoggerImpl in the OJB .properties file.
If you want log4j to initialize from a property file you can add LoggerConfigFile=log4j.properties to the org.apache.ojb.properties file. the logger only initializes log4j if the application hasn't done it yet You can find sample log4j.properties file in the log4j web site http://jakarta.apache.org/log4j in the javadoc look for org.apache.log4j.examples
