Note this example is somewhat dated. It predates the schedule API which was added to EJB 3.1. Modern applications should use the schedule API which has many, if not all, the same features as Quartz. In fact, Quartz is the engine that drives the @Schedule and ScheduleExpression support in OpenEJB and TomEE.

Despite being dated from a scheduling perspective it is still an excellent reference for how to plug-in and test a custom Java EE Resource Adapter.

Project structure

As .rar files do not do well on a standard classpath structure the goal is to effectively "unwrap" the .rar so that its dependencies are on the classpath and its ra.xml file can be found in scanned by OpenEJB.

We do this by creating a mini maven module to represent the rar in maven terms. The pom.xml of the "rar module" declares all of the jars that would be inside .rar as maven dependencies. The ra.xml file is added to the project in src/main/resources/META-INF/ra.xml where it will be visible to other modules.



The connector in question has both inbound and outbound Resource Adapters. The inbound Resource Adapter can be used to drive message driven beans (MDBs)

the outbound Resource Adapter, QuartzResourceAdapter, can be injected into any component via @Resource and used to originate and send messages or events.

<connector xmlns=""

  <description>Quartz ResourceAdapter</description>
  <display-name>Quartz ResourceAdapter</display-name>

  <eis-type>Quartz Adapter</eis-type>

  <resourceadapter id="QuartzResourceAdapter">



Using the Outbound Resource Adapter

Here we see the outbound resource adapter used in a stateless session bean to schedule a job that will be executed by the MDB

package org.superbiz.quartz;

import org.apache.openejb.resource.quartz.QuartzResourceAdapter;
import org.quartz.Job;
import org.quartz.JobDetail;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.Scheduler;
import org.quartz.SimpleTrigger;

import javax.ejb.Stateless;
import javax.naming.InitialContext;
import java.util.Date;

public class JobBean implements JobScheduler {

    public Date createJob() throws Exception {

        final QuartzResourceAdapter ra = (QuartzResourceAdapter) new InitialContext().lookup("java:openejb/Resource/QuartzResourceAdapter");
        final Scheduler s = ra.getScheduler();

        //Add a job type
        final JobDetail jd = new JobDetail("job1", "group1", JobBean.MyTestJob.class);
        jd.getJobDataMap().put("MyJobKey", "MyJobValue");

        //Schedule my 'test' job to run now
        final SimpleTrigger trigger = new SimpleTrigger("trigger1", "group1", new Date());
        return s.scheduleJob(jd, trigger);

    public static class MyTestJob implements Job {

        public void execute(JobExecutionContext context) throws JobExecutionException {
            System.out.println("This is a simple test job to get: " + context.getJobDetail().getJobDataMap().get("MyJobKey"));

Recieving data from the Inbound Resource Adapter

package org.superbiz.quartz;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;

@MessageDriven(activationConfig = {
        @ActivationConfigProperty(propertyName = "cronExpression", propertyValue = "* * * * * ?")})
public class QuartzMdb implements Job {

    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("Executing Job");

Test case

package org.superbiz.quartz;

import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;

import javax.naming.Context;
import javax.naming.InitialContext;
import java.util.Date;
import java.util.Properties;

public class QuartzMdbTest {

    private static InitialContext initialContext = null;

    public static void beforeClass() throws Exception {

        if (null == initialContext) {
            Properties properties = new Properties();
            properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.core.LocalInitialContextFactory");

            initialContext = new InitialContext(properties);

    public static void afterClass() throws Exception {
        if (null != initialContext) {
            initialContext = null;

    public void testLookup() throws Exception {

        final JobScheduler jbi = (JobScheduler) initialContext.lookup("JobBeanLocal");
        final Date d = jbi.createJob();
        System.out.println("Scheduled test job should have run at: " + d.toString());

    public void testMdb() throws Exception {
        // Sleep 3 seconds and give quartz a chance to execute our MDB
