Subclassing java.util.logging.Formatter doesn't work

Question

I am using java.util.logging for logging (I don\'t want to use log4j or anything else).

This is my complete private logging.properties:

com.mycomp.myproj.LogFormatter is not in your system class path.

LogManager will do the following call for loading your class:

Formatter getFormatterProperty(String name, Formatter defaultValue) {
        String val = getProperty(name);
        try {
            if (val != null) {
                Class clz = ClassLoader.getSystemClassLoader().loadClass(val);
                return (Formatter) clz.newInstance();
            }
        } catch (Exception ex) {
            // We got one of a variety of exceptions in creating the
            // class or creating an instance.
            // Drop through.
        }
        // We got an exception.  Return the defaultValue.
        return defaultValue;
}

You need to make sure your class LogFormatter is in the system's class path.
