Set the openjpa.Log property to commons to
use the Apache
Commons Logging thin library for issuing log messages. The
Commons Logging library act as a wrapper around a number of popular logging
APIs, including the
Jakarta Log4J
project, and the native
java.util.logging package in JDK.
When using the Commons Logging framework in conjunction with Log4J, configuration will be the same as was discussed in the Log4J section above.
When using JDK logging in conjunction with OpenJPA's Commons Logging support, logging will proceed through Java's built-in logging provided by the java.util.logging package. For details on configuring the built-in logging system, please see the Java Logging Overview.
By default, JDK's logging package looks in the
JAVA_HOME/lib/logging.properties file for logging configuration. This
can be overridden with the java.util.logging.config.file
system property. For example:
java -Djava.util.logging.config.file=mylogging.properties com.company.MyClass
Example 3.5. JDK Log Properties
# specify the handlers to create in the root logger
# (all loggers are children of the root logger)
# the following creates two handlers
handlers=java.util.logging.ConsoleHandler, java.util.logging.FileHandler
# set the default logging level for the root logger
.level=ALL
# set the default logging level for new ConsoleHandler instances
java.util.logging.ConsoleHandler.level=INFO
# set the default logging level for new FileHandler instances
java.util.logging.FileHandler.level=ALL
# set the default formatter for new ConsoleHandler instances
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
# set the default logging level for all OpenJPA logs
