16.2. Simple Example of Using Logging

Changing the log levels and output destination

To change the log level and output destination of the log messages in the wsdl_first sample application, complete the following steps:
  1. Run the sample server as described in the Running the demo using java section of the README.txt file in the InstallDir/samples/wsdl_first directory. Note that the server start command specifies the default logging.properties file, as follows:
    PlatformCommand
    Windows start java -Djava.util.logging.config.file=%CXF_HOME%\etc\logging.properties demo.hw.server.Server
    UNIX java -Djava.util.logging.config.file=$CXF_HOME/etc/logging.properties demo.hw.server.Server &
    The default logging.properties file is located in the InstallDir/etc directory. It configures the Apache CXF loggers to print WARNING level log messages to the console. As a result, you see very little printed to the console.
  2. Stop the server as described in the README.txt file.
  3. Make a copy of the default logging.properties file, name it mylogging.properties file, and save it in the same directory as the default logging.properties file.
  4. Change the global logging level and the console logging levels in your mylogging.properties file to INFO by editing the following lines of configuration: 
    .level= INFO
java.util.logging.ConsoleHandler.level = INFO
  5. Restart the server using the following command:
    PlatformCommand
    Windows start java -Djava.util.logging.config.file=%CXF_HOME%\etc\mylogging.properties demo.hw.server.Server
    UNIX java -Djava.util.logging.config.file=$CXF_HOME/etc/mylogging.properties demo.hw.server.Server &
    Because you configured the global logging and the console logger to log messages of level INFO, you see a lot more log messages printed to the console.
