To be honest I didn't found a way to add this line: -Djava.util.logging.config.file=mylogging.properties
to an Web Dynamic Project that deploys on Tomcat Server. If you know how to this, pls let me know. In the meantime I found an other solution. I wrote a static class with this input: Logger log = Logger.getLogger("myApp"); log.setLevel(Level.ALL); log.info("initializing - trying to load configuration file ..."); Properties preferences = new Properties(); try { FileInputStream configFile = new FileInputStream("/path/to/app.properties"); preferences.load(configFile); LogManager.getLogManager().readConfiguration(configFile); } catch (IOException ex) { System.out.println("WARNING: Could not open configuration file"); System.out.println("WARNING: Logging not configured (console output only)"); } log.info("starting myApp"); Now when the application starts, the properties file will be read by Log Manager and openjpa logs in the configured file. But I have the feeling that this does not work so good as I hoped. So I swapped back to normal openJpa Logging mode for openJPA Log. And the other things will be logged by Java. Now an other question. Is there a possibility to add date and time to the normal openJPA logging mode, that I configured like that: <property name="openjpa.Log" value="File=logs/org.apache.openjpa.log, DefaultLevel=WARN, Runtime=WARN, Tool=WARN, SQL=WARN"/> I nedd a prefix with date and time for the log messages.
