If that fails, then the "quartz.properties" * file located (as a resource) in the org/quartz package is loaded. If you * wish to use a file other than these defaults, you must define the system * property 'org.quartz.properties' to* point to the file you want. * </p> *  * <p> * See the sample properties files that are distributed with Quartz for * information about the various settings available within the file. * </p> *  * <p> * Alternativly, you can explicitly initialize the factory by calling one of * the <code>initialize(xx)</code> methods before calling <code>getScheduler()</code>. * </p> *  * <p> * Instances of the specified <code>{@link org.quartz.spi.JobStore}</code>, * <code>{@link org.quartz.spi.ThreadPool}</code>, classes will be created * by name, and then any additional properties specified for them in the config * file will be set on the instance by calling an equivalent 'set' method. For * example if the properties file contains the property 'org.quartz.jobStore. * myProp = 10' then after the JobStore class has been instantiated, the method * 'setMyProp()' will be called on it. Type conversion to primitive Java types * (int, long, float, double, boolean, and String) are performed before calling * the propertie's setter method. * </p> *  * @author James House * @author Anthony Eden * @author Mohammad Rezaei */public class StdSchedulerFactory implements SchedulerFactory {    /*     * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~     *      * Constants.     *      * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~     */    public static final String PROPERTIES_FILE = "org.quartz.properties";
