Example 7 with ClassLoadHelper

use of org.quartz.spi.ClassLoadHelper in project weicoder by wdcode.

the class DirectSchedulerFactory method createScheduler.

/**
 * Creates a scheduler using the specified thread pool, job store, and
 * plugins, and binds it to RMI.
 *
 * @param schedulerName
 *          The name for the scheduler.
 * @param schedulerInstanceId
 *          The instance ID for the scheduler.
 * @param threadPool
 *          The thread pool for executing jobs
 * @param threadExecutor
 *          The thread executor for executing jobs
 * @param jobStore
 *          The type of job store
 * @param schedulerPluginMap
 *          Map from a <code>String</code> plugin names to
 *          <code>{@link org.quartz.spi.SchedulerPlugin}</code>s.  Can use
 *          "null" if no plugins are required.
 * @param rmiRegistryHost
 *          The hostname to register this scheduler with for RMI. Can use
 *          "null" if no RMI is required.
 * @param rmiRegistryPort
 *          The port for RMI. Typically 1099.
 * @param idleWaitTime
 *          The idle wait time in milliseconds. You can specify "-1" for
 *          the default value, which is currently 30000 ms.
 * @param maxBatchSize
 *          The maximum batch size of triggers, when acquiring them
 * @param batchTimeWindow
 *          The time window for which it is allowed to "pre-acquire" triggers to fire
 * @throws SchedulerException
 *           if initialization failed
