example1
Example 1
=========
Overview:
=========
This example will demonstrate how to quickly get quartz up
and running and how to schedule a simple job.
Running the Example:
====================
1\. Windows users - Modify the example1.bat file (if necessary)
to set your JAVA_HOME. Run example1.bat
2\. UNIX/Linux users - Modify the example1.sh file (if necessary)
to set your JAVA_HOME. Execute example1.sh
Configuration Files:
====================
1\. You can decide to specify a log4j.properties file to
control logging output (optional)
public class SimpleExample {
public void run() throws Exception {
Logger log = LoggerFactory.getLogger(SimpleExample.class);
log.info("------- Initializing ----------------------");
// First we must get a reference to a scheduler
SchedulerFactory sf = new StdSchedulerFactory();
Scheduler sched = sf.getScheduler();
log.info("------- Initialization Complete -----------");
// computer a time that is on the next round minute
Date runTime = evenMinuteDate(new Date());

// Tell quartz to schedule the job using our trigger
sched.scheduleJob(job, trigger);

// Start up the scheduler (nothing can actually run until the
// scheduler has been started)

// run the job!

to set your JAVA_HOME. Run example2.bat
2\. UNIX/Linux users - Modify the example2.sh file (if necessary)
to set your JAVA_HOME. Execute example2.sh
