/**
 * <p>
 * A Servlet that can be used to initialize Quartz, if configured as a
 * load-on-startup servlet in a web application.
 * </p>
 *
 * <p>
 * You'll want to add something like this to your WEB-INF/web.xml file:
 *
 * <pre>
 *     &lt;servlet&gt;
 *         &lt;servlet-name&gt;
 *             QuartzInitializer
 *         &lt;/servlet-name&gt;
 *         &lt;display-name&gt;
 *             Quartz Initializer Servlet
 *         &lt;/display-name&gt;
 *         &lt;servlet-class&gt;
 *             org.quartz.ee.servlet.QuartzInitializerServlet
 *         &lt;/servlet-class&gt;
 *         &lt;load-on-startup&gt;
 *             1
 *         &lt;/load-on-startup&gt;
 *         &lt;init-param&gt;
 *             &lt;param-name&gt;config-file&lt;/param-name&gt;
 *             &lt;param-value&gt;/some/path/my_quartz.properties&lt;/param-value&gt;
 *         &lt;/init-param&gt;
 *         &lt;init-param&gt;
 *             &lt;param-name&gt;shutdown-on-unload&lt;/param-name&gt;
 *             &lt;param-value&gt;true&lt;/param-value&gt;
 *         &lt;/init-param&gt;
 *         &lt;init-param&gt;
 *             &lt;param-name&gt;start-scheduler-on-load&lt;/param-name&gt;
 *             &lt;param-value&gt;true&lt;/param-value&gt;
 *         &lt;/init-param&gt;
 *     &lt;/servlet&gt;
 * </pre>
 *
 * </p>
 * <p>
 * The init parameter 'config-file' can be used to specify the path (and
 * filename) of your Quartz properties file. If you leave out this parameter,
 * the default ("quartz.properties") will be used.
 * </p>
 *
 * <p>
 * The init parameter 'shutdown-on-unload' can be used to specify whether you
 * want scheduler.shutdown() called when the servlet is unloaded (usually when
 * the application server is being shutdown). Possible values are "true" or
 * "false". The default is "true".
 * </p>
 *
 * <p>
 * The init parameter 'start-scheduler-on-load' can be used to specify whether
 * you want the scheduler.start() method called when the servlet is first loaded.
 * If set to false, your application will need to call the start() method before
 * the scheduler begins to run and process jobs. Possible values are "true" or
 * "false". The default is "true", which means the scheduler is started.
 * </p>
 *
 * A StdSchedulerFactory instance is stored into the ServletContext. You can gain access
 * to the factory from a ServletContext instance like this:
 * <br>
 * <pre>
 *     StdSchedulerFactory factory = (StdSchedulerFactory) ctx
 *                .getAttribute(QuartzFactoryServlet.QUARTZ_FACTORY_KEY);</pre>
 * <p>
 * The init parameter 'servlet-context-factory-key' can be used to override the
 * name under which the StdSchedulerFactory is stored into the ServletContext, in 
 * which case you will want to use this name rather than 
 * <code>QuartzFactoryServlet.QUARTZ_FACTORY_KEY</code> in the above example.
 * </p>
 * 
 * Once you have the factory instance, you can retrieve the Scheduler instance by calling
 * <code>getScheduler()</code> on the factory.
