Java.util.logging: write to one log file from many application (classes)

Question

I have a menuapp to launch many applications, all running in same JVM and i want to add logging information to them, using java.util.logging.
Intention is to redirect the logginginfo to a specific file within the menuapp. Then i want all logging from all applications written in same file. Finally, if needed (but i don't think it is), i will include code to write logging to specific file per app (class). The latter is probably not neccessary because there are tools to analyse the logging-files and allow to select filters on specific classes only.
The applications are in their own packages/jars and contain following logging-code:
        // Redirect error output
        try {
            myHandler = new FileHandler("myLogging.xml",1000000,2);
        } catch (IOException e) {
          System.out.println("Could not create file. Using the console handler");
        myLogger.addHandler(myHandler);
        myLogger.info("Our first logging message");
        myLogger.severe("Something terrible happened");
        ...When i launch the menuapplication, it writes info to "myLogging.xml.0"
but when i launch an application, the app writes info to "myLogging.xml.0.1"
I already tried to leave out the creation of a new Filehandler (try/catch block in code above) but it doesn't help.
Is it possible to write loginfo to same specific file?

Answer 1

You should open/close it somehow at every write from different processes.
But I personally prefer different file names to your forced merging, though.
