Info
titleAbout Quartz

Quartz is a full-featured, open source job scheduling system that can be integrated with, or used along side virtually any J2EE or J2SE application. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components or EJBs.

  • Integrating Quartz with the framework requires some glue code.

Coding a Quartz ActionJob

Code Block
titleActionJob.java

The following class performs the glue between Quartz and Webwork:

Code Block
package com.trantek.sit.action;

import com.opensymphony.xwork.ActionProxy;
import com.opensymphony.xwork.ActionProxyFactory;
import com.opensymphony.xwork.interceptor.component.ComponentInterceptor;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import java.util.HashMap;

public class WebWorkJobActionJob implements Job
{
    public void execute(JobExecutionContext context) throws JobExecutionException
    {
        try
        {
            HashMap ctx = new HashMap();
            ctx.put(ActionContext.PARAMETERS, context.getJobDetail().getJobDataMap());
            ctx.put(ComponentInterceptor.COMPONENT_MANAGER, ???);
            ctx.put(???, ???)
            ServletDispatcher.createContextMap()
            ActionProxy proxy = ActionProxyFactory.getFactory().
                    createActionProxy("", context.getJobDetail().getName(), ctx);

            proxy.execute();
        }
        catch (Exception e)
        {
            throw new JobExecutionException(e);
        }
    }
}

To schedule webwork actions you simply Actions to be run by Quartz, create a job Job where

  • the The name of your job is the name of the WW action Action to execute (no ".action" equivalent suffix).
  • all All the parameters you want to send to the WW action is contained in being sent to the Action are provided by the JobDataMap of the JobDetail

...

  • object.
    Info

    According to the Javadocs of org.quartz.ee.servlet.QuartzInitializerServlet

...

  • , the Quartz scheduler is setup as a servlet.

Sample Quartz Email Action

The following code schedules an e-mail action:

Code Block
java
java
titleScheduling an Email Alert
Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();

JobDetail jobDetail = new JobDetail("email.send", 
                                     scheduler.DEFAULT_GROUP, WebWorkJob.class);

Map m = jobDetail.getJobDataMap();
m.put("to", "me@bogusdomain.com");
m.put("subject", "quartz test");
m.put("body", "This is a quartz test, Hey ho");
m.put("smtpServer", "smtp.bogusdomain.com");
m.put("from", "quartz@bogusdomain.com");

SimpleTrigger trigger = new SimpleTrigger("myTrigger", 
                                          scheduler.DEFAULT_GROUP, 
                                          new Date(), null, 0, 0L);

scheduler.deleteJob("email.send", scheduler.DEFAULT_GROUP);
scheduler.scheduleJob(jobDetail, trigger);
