Examples of org.quartz.impl.DirectSchedulerFactory

org.quartz.impl.DirectSchedulerFactory

hreads * // don't forget to start the scheduler: DirectSchedulerFactory.getInstance().getScheduler().start();

Several create methods are provided for convenience. All create methods eventually end up calling the create method with all the parameters:

 public void createScheduler(String schedulerName, String schedulerInstanceId, ThreadPool threadPool, JobStore jobStore, String rmiRegistryHost, int rmiRegistryPort)

Here is an example of using this method:

* *

// create the thread pool SimpleThreadPool threadPool = new SimpleThreadPool(maxThreads, Thread.NORM_PRIORITY); threadPool.initialize(); * // create the job store JobStore jobStore = new RAMJobStore(); DirectSchedulerFactory.getInstance().createScheduler("My Quartz Scheduler", "My Instance", threadPool, jobStore, "localhost", 1099); * // don't forget to start the scheduler: DirectSchedulerFactory.getInstance().getScheduler("My Quartz Scheduler", "My Instance").start();

You can also use a JDBCJobStore instead of the RAMJobStore:

 DBConnectionManager.getInstance().addConnectionProvider("someDatasource", new JNDIConnectionProvider("someDatasourceJNDIName")); JobStoreTX jdbcJobStore = new JobStoreTX(); jdbcJobStore.setDataSource("someDatasource"); jdbcJobStore.setPostgresStyleBlobs(true); jdbcJobStore.setTablePrefix("QRTZ_"); jdbcJobStore.setInstanceId("My Instance");
