Using the JRE Logging Configuration File

The following example shows how you set logging name spaces and levels in the JRE_DIRECTORY/lib/logging.properties file, which is used to set the log level for the Java runtime environment. All applications using this JRE will have the same logging configuration. The sample configuration below sets the logging level to INFO for the javax.jms.connection name space and specifies that output be written to java.util.logging.ConsoleHandler.

#logging.properties file.
# "handlers" specifies a comma separated list of log Handler 
# classes. These handlers will be installed during VM startup.
# Note that these classes must be on the system classpath.
# By default we only configure a ConsoleHandler, which will only
# show messages at the INFO and above levels.

	handlers= java.util.logging.ConsoleHandler

# Default global logging level.
# This specifies which kinds of events are logged across
# all loggers. For any given facility this global level
# can be overriden by a facility-specific level.
# Note that the ConsoleHandler also has a separate level
# setting to limit messages printed to the console.

    .level= INFO

# Limit the messages that are printed on the console to INFO and above.

    java.util.logging.ConsoleHandler.level = INFO
    java.util.logging.ConsoleHandler.formatter = 
                                    java.util.logging.SimpleFormatter

# The logger with javax.jms.connection name space will write
# Level.INFO messages to its output handler(s). In this configuration 
# the ouput handler is set to java.util.logging.ConsoleHandler.

    javax.jms.connection.level = INFO
