Thanks Jim,


I created a class using this example, but cannot get the output to show. I get all levels but the TRACE level. Can anyone point out what I am doing wrong please?

Thanks

The test class:

import org.apache.log4j.*;

public class TestLogging {

    // Initialize a logging category.  Here, we get THE ROOT CATEGORY
    //static Category cat = Category.getRoot();
    // Or, get a custom category
    static Category cat = Category.getInstance(TestLogging.class.getName());

    public static void main(String args[]) {
        // Try a few logging methods
                cat.setAdditivity(true); //--> Will append
        cat.debug("Start of main()");
                cat.log(TraceLevel.TRACE, "Got here");
        cat.info("Testing a log message with priority set to INFO");
        cat.warn("Testing a log message with priority set to WARN");
        cat.error("Testing a log message with priority set to ERROR");
        cat.fatal("Testing a log message with priority set to FATAL");
                cat.log(Level.ERROR, "Test ERROR message");

        new TestLogging().init();
    }

    public void init() {
        java.util.Properties prop = System.getProperties();
        java.util.Enumeration enum = prop.propertyNames();

        cat.info("***System Environment As Seen By Java***");
        cat.debug("***Format: PROPERTY = VALUE***");

        while (enum.hasMoreElements()) {
            String key = (String) enum.nextElement();
            cat.info(key + " = " + System.getProperty(key));
        }
    }

}


The config file: #### Use two appenders, one to log to console, another to log to a file log4j.rootCategory=DEBUG, stdout, R

# Print only messages of priority WARN or higher for your category
log4j.category.your.category.name=DEBUG

#### First appender writes to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout


# Pattern to output the caller's file name and line number. log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

#### Second appender writes to a file
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log

# Control the maximum log file size
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
