Featured Article: Using the Quartz Enterprise Scheduler in J2EE (46 messages)
- Posted by: Dion Almaer

Debu Panda of Oracle has written about the Quartz Scheduler, which is the open source equivalent of cron for J2EE. Debu walks you through an example of scheduling a job using the Quartz API.
Quartz is an open source enterprise job scheduler from Open Symphony project. For details and downloading Quartz please look at http://www.quartzscheduler.org/quartz/. You can use Quartz to schedule jobs in your J2EE applications such as EJBs. This article will describe Quartz can be used in your J2EE applications to schedule cron like jobs. This will include how to configure Quartz in J2EE containers taking Oracle Application Server 10g Containers for J2EE (OC4J 9.0.4) as an example.

A couple of things:

1) It would be helpful to show an example of how to configure Quartz to work without a custom servlet. It can be done and is probably the most likely way people will use it within a J2EE application. I recently implemented something like this, and had to figure it out for myself since the Quartz docs weren't very explicit. Basically, you
-Configure your web app to use the Quartz initializer servlet, loading on startup. For example (from web.xml):
<servlet>
<servlet-name>quartz</servlet-name>
<display-name>Quartz Initializer Servlet</display-name>
<servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
-Add a "quartz.properties" file to your classpath, indicating how jobs will be loaded (as well as the quartz system properties). For example (from quartz.properties):
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.fileName = quartz-jobs.xml
org.quartz.plugin.jobInitializer.overWriteExistingJobs = true
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
-Add an xml file configuring your jobs and triggers, using the file name specified under the "org.quartz.plugin.jobInitializer.fileName" property.
For example (from quartz-jobs.xml, in this case):
<job>
    <job-detail>
      <name>alertJob</name>
      <group>alertJobs</group>
      <job-class>com.somecompany.AlertJob</job-class>
      <volatility>false</volatility>
      <durability>false</durability>
      <recover>false</recover>
    </job-detail>
    <trigger>
      <cron>
        <name>dailyTrigger</name>
        <group>alertTriggers</group>
        <job-name>alertJob</job-name>
        <job-group>alertJobs</job-group>
        
        <cron-expression>0 15 2 ? * MON-FRI</cron-expression>
      </cron>
    </trigger>
  </job>
Again, I think this is the most flexible, easy to use way to implement quartz, and I'm surprised it's not documented better. In most systems I use, I don't want to hard-code something like a scheduled process that might be subject to frequent scheduling change.

2) The author mentions the "userThreads" setting for application servers to allow Quartz to use user threads. Unfortunately, I'm kind of thread-dumb, so I don't exactly know what this means or why it's important. What happens if Quartz is deployed without this setting? What implications does this setting have to other aspects of server performance (will it cause a conflict with some other setting)? I actually am in the middle of deploying an app that uses Quartz on OC4J and would like to be aware of the implications and necessity of this setting.

Thanks,

Drew

Drew,
Thanks for the example without having to use a Custom Servlet. I was creating this for very customers that wanted to use cron type triggers with EJBs. I tried to venture this way but could not make this work for an EJB methods. This works great for Java classes though.

Quartz uses its own thread pools and are not container managed threads and it's cannot use the thread pooling from the container. Even I had problems firing Triggers/Jobs when I disabled User Threads.

Please make sure that you do not set the max threads to very high in the quartz.properies file. According to Quartz doc:"A maximum of 5 should be fine for a typical application".

Hope this helps..

regards
Debu

Debu,

Thanks for the info on EJBs. I've been using an EJB-less environment. As far as user threads are concerned, right now I only have one job running nightly. I've configured 2 threads. Should I be concerned?

Also, in the deployment environment, the server is running a full 9iAS install, not just the oc4j container. So I can't just run the oc4j jar with a user threads switch. Any ideas on how to enable that setting in the 9iAS server? Perhaps there's a console setting? Also, I'm still unclear if this setting has any impact on any other parts of the system, or if there's any situation I should be aware of that this setting might cause.

Thanks,

Drew

>> You can set the -userThreads in the OC4J options in the Advanced Settings for your OC4J instance.

Use Message-Driven Beans[ Go to top ]
- Posted by: Te Vo
- Posted on: April 07 2004 01:23 EDT
- in response to Debu Panda
A technique I've seen used with Quartz and EJB Methods was to let the Quartz jobs simply send JMS messages that trigger message-bean driven beans. Works great, even if Quartz is embedded within an application server, either using the servlet or - what we did with WebLogic - custom-written startup-classes.

Is there any particular reason why the "QuartzServlet" couldn't be replaced with a "QuartzServletContextListener" which performs the same tasks upon application deployment?

Here's the code from the Quartz servlet that sets up the scheduler:
public void init(ServletConfig cfg) throws javax.servlet.ServletException {
        super.init(cfg);

        log("Quartz Initializer Servlet loaded, initializing Scheduler...");

        try {

            StdSchedulerFactory.getDefaultScheduler().start();

        } catch (Exception e) {
            log("Quartz Scheduler failed to initialize: " + e.toString());
            throw new ServletException(e);
        }
    }

    public void destroy() {
        try {
            Scheduler sched = StdSchedulerFactory.getDefaultScheduler();

            if (sched != null) sched.shutdown();
        } catch (Exception e) {
            log("Quartz Scheduler failed to shutdown cleanly: " + e.toString());
            e.printStackTrace();
        }

        log("Quartz Scheduler successful shutdown.");
    }
From what I can tell, there's no reason that can't be wrapped in a context listener. That's actually not a bad idea, because then your app is a little more portable. I've found that some servers handle the startup parameter on a servlet (in WEB-INF) differently. If I'm not mistaken, Tomcat treats it as a boolean, and I know that Orion and OC4J treat it as a number, to specify the order of load (I vaguely recall that the servlet spec doesn't force it one way or the other). Using a context listener avoids this issue altogether. Though of course then you'd to deal with the fact that it wouldn't run on older servlet specs.

Thanks for the tip; I may go ahead and change my app to do this. I may even contribute the results back into Quartz.

OK if quartz.properties and jobs.xml are kept in /WEB-INF/classes then quartz is able to see it. In web.xml then just define the quartz init servlet as

<servlet>
<servlet-name>quartz</servlet-name>
<display-name>Quartz Initializer Servlet</display-name>
<servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

That should do it.

"quartz-jobs.xml" vs RAM or JDBCJobStore[ Go to top ]
- Posted by: ohIDidntKnowThat ohIDidntKnowThat
- Posted on: March 31 2005 10:17 EST
- in response to Drew McAuliffe
Drew,
I have not tried your method..but sounds promising for what I have to do.
I am EXTREMELY confused after reading all the quartz documentations out there(ranging from the opensymphony tutorial, Debu's article, Bosanac's o'reilly article, JLG plugin documentation at http://demo.jgsullivan.com/struts/QuartzPlugIn.html and your input:-)..My brain hurts:) Ignorance is a bliss, ain't it?:)

In my case I have a Struts action class which implements the StatefulJob interface (why struts? Because my whacky customer wants to run the job at his whim and fancy..grrr!-where do these people come from ?? - Well not as a chron job..but just to run it at any point in time). So I did the struts action class implementing the StatefulJob interface. Two birds in one shot..same action file can be used as just a job and also as a chron job (this is what prompted me to look at the sketchy documentation of the JLG plugin mentioned above, but that confused me more..as they mention nothing about how to use the JDBCJobStore in there)

My question is this:- if I use the "quartz-jobs.xml" and set it in the quartz.properties like you(Drew) have suggested...AND if I ALSO use the JDBCJobStore, which settings take precedence...Is that the ones in the "quartz-jobs.xml" or the JDBCJobStore table..

Also what takes precedence if I use the "quartz-jobs.xml" and a RAMJobDataStore?

Before I had a regular servlet doing the same thing but triggered by a crontab job. The EJB is there on that JNDI name.

Any idea?

I have removed the 'java:comp/env/' and just have the value from ejb-ref-name in web.xml.
Now it can find the EJB but the method I want to use have both input argument and return value. I don't need the return value but I must use the argument. Therefore I have:

JobDetail jd = new JobDetail("SystemStatus Trigger", "SystemStatus Trigger Job", EJBInvokerJob.class);
jd.getJobDataMap().put("ejb", "ejb/vadis2004/integration/core/systempollerws");
jd.getJobDataMap().put("method", "forcePollSystems");
Object[] jdArgs = {new ForcePollSystemsRequest()};
jd.getJobDataMap().put("args", jdArgs);

now I get:

java.lang.NoSuchMethodException: forcePollSystems

I think I got the solution. I changed where the method is fetched from the original:
methodExecute = remoteClass.getDeclaredMethod(method, argTypes);

To the new one:

methodExecute = remoteClass.getMethod(method, argTypes);

At this moment Quartz is quite unstable and buggy:
v 1.3.3 does not execute all jobs which were scheduled to run at the same time, v 1.3.4 fixed the problem but CronTrigger does not work with day-of-week specs.

Quartz bug database suddenly became empty and does not allow submitting new bugs now :((((

userThreads setting in JDEV[ Go to top ]
- Posted by: Christopher Buchholz
- Posted on: June 08 2004 18:56 EDT
- in response to Dion Almaer
Thanks for the great article, I am working on implementing a job scheduler within a J2EE container running on OC4J right now, so this really helps! :-)

Since you're using OC4J over Oracle, I was hoping maybe you also used JDev, and if so, do you know where I can find a userThreads setting within JDev (for when I just run the server on my own computer for development).

For example, I hit the "debug" button to start up the OC4J appserver and deploy the app and run it (on my local machine). Somewhere I must be able to configure it to send that userThreads command line parameter, I just can't find where.

Thanks,

userThreads setting in JDEV[ Go to top ]

- in response to Christopher Buchholz
Hello everybody:

As Christopher, I am using JDev to develope an application which use Quartz to schedule jobs, and I am having some troubles with threads and deadlocks. After reading all documentation and trying all the reasonable combination of properties configuration, I think that my problems is related to the userThreads configuration that Debu mention in his useful article.

So, If someone could help us (Christopher and me), I need to configure JDev to use user threads in debugging mode.

Thanks in advance,
Antonio Crespo.

Configure userThreads in JDev[ Go to top ]
- Posted by: Antonio Crespo
- Posted on: September 23 2004 10:18 EDT
- in response to Christopher Buchholz
Hello:

I have found where to configure the '-useThreads' parameter in JDeveloper 10g for run/debug mode.
- Select the project which you want to set with the above parameter.
- Go to Tools > Project properties...
- Select 'J2EE' in the tree of the left panel.
- In the box labeled with 'Embedded OC4J Command Line' add at the end of the command the parameter '-useThreads'. The command after that should appear like this:
   ${java} ${jvm} -classpath ${oc4j.jar} ${java.options}
   ${memory.archive.flag} ${keep.alive.timeout.flag}
   ${oracle.dms.sensors.flag} ${oracle.jms.lock.flag}
   ${oc4j.main.class} -config ${server.xml} -userThreads

Hope it will be useful for someone.
Antonio.

Does running in container work with clustering[ Go to top ]
- Posted by: Scott Vallely
- Posted on: November 03 2004 15:14 EST
- in response to Dion Almaer
Will running Quartz in container work with clustering? Its's started by a servet when each node is started, with the web.xml tag - "load-on-startup" - so there's one quartz instance per node. Does this mean you'll get duplicate jobs?
Also, quartz is multi-threaded, so running in a J2EE address space is dubious and requires running the app server with -useThreads to enable it.

The J2EE 1.4 spec makes it clear that the creation of threads from within an enterprise app is at the very least strongly discouraged. Section 6.2.1 makes it pretty clear:

"...
For example, if enterprise beans were allowed to manage threads, the J2EE platform could not manage the life cycle of the enterprise beans, and it could not properly manage transactions.
..."

Section 4.2.1.1 opens the door to creating threads in a webapp, but makes it clear that problems could occur:

"...
If a web component creates a thread, the J2EE platform must ensure that the newly created thread is not associated with any JTA transaction.
..."

So the idea of starting Quartz in a servlet, although it may work in some containers, goes against the intent of the J2EE spec designers, and could break your applications in unforseen ways. You may have to make changes to security policies to enable this, but then you have to be sure you know what you're doing.

I found your article very interesting.
And i use quartz for xml file creation scheduling.
But i cannot use quartz with log4j !
I have to put some jar file in the home/lib directory of the oc4j instance and reference them in the server.xml(init-library path=....) file.
But the process can't write the log file.
Thank you.

I'm having problems using quartz in JBOSS. This problem is related to the user Threads.
I want to know the similar command for enabling User Threads in JBOSS (like -userThreads in OC4J).

I currently use Spring application framework and Quartz, the using them combined has made intergration very simple!

grab a refrence to org.springframework.scheduling.quartz.SchedulerFactoryBean
in a servelet like..
WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext( servletContext );

StdScheduler myScheduler = ( StdScheduler ) wac.getBean( "mySchedulere" );

myScheduler, is a bean in the applicationContenxt.

when you want to add trigger's,and jobs dynamitically, OR add the trigger and job information to the applicationContenxt.xml

i've deleted tons of code using this.

I am deploying quartz scheduler as a mbean in jboss, and looking it up by jndi. The jboss server startup the quartz scheduler itself, but you must use database to maintain the state of all the jobs.

I am just wondering if there are anyways to invoke a job there is in another machine, such as having Machine A invoke method in Machine B and its resource.

Using Quartz for BIG jobs[ Go to top ]

I am planning to use quartz in my next project to run BIG jobs. I mean these may take a bit of time to execute, say 5-10 minutes or so. These jobs do some data extractions and generate a huge data file, which might load up the system. Should there be a problem using quartz for this. The application is simple J2EE with hibernate + spring and no ejbs.

Also, I read in the same message thread that there is a problem in scheduling weekly cron jobs. Is this still a problem. I plan to use quartz for mostly weekly jobs.

I read you comment containing Quartz in J2EE and you described the thing i am planning to do. I want to to use the TimerTask which is implemented in Quartz. My setting values should come from the database(JDBC) and my Bean should start automatically with my JBOSS Server. But I have no clue where i have to start. Maybe you can tell me some steps which may help a little bit. How can I make a Bean or how can I deploy this Bean to the JBoss Server. Those are some questions i delve with! It would be nice if you could answer some :-).

Thanks
Anna

i have configured my quartz and running. my bean method which runs as a scheduled quartz job is as follows:: public void doJob() throws Exception{ TestLocalHome tl = null; TestLocal th = null; try{ InitialContext ic = new InitialContext(); tl = (TestLocalHome)ic.lookup("java:comp/env/ejb/Test"); th = tl.create("name"); }catch (Exception e){ System.out.println e.printStackTrace(); } } The method is trying to access another entity bean called Test within the application. I am getting the following exception when this method executes. i have tried looking up the bean like :: tl = (TestLocalHome)ic.lookup("ejb/Test"); and still it fails to work.

Quartz invoking an EJB method[ Go to top ]
- Posted by: Harald Busch
- Posted on: January 20 2009 02:11 EST
- in response to Dion Almaer
Hello, I got an exception (see below) while trying to invoke an EJB method which I try to schedule from within a servlet via EJBInvokerJob.class. I use GlassFish v2ur2 and Quartz 1.6.4 and there are no security restrictions on that EJB. The security manager in GlassFish is turned off. It seems that Quartz is not allowed to invoke it due to the following reading: java.rmi.AccessException: Client is not authorized for this invocation. Did anybody face a similar problem and found a solution ? Thanks for your help. 2009-01-20 08:06:10,231: {INFO} core.JobRunShell Job Report Generation.Income Report threw a JobExecutionException: org.quartz.JobExecutionException: java.rmi.AccessException: CORBA NO_PERMISSION 9998 Maybe; nested exception is: org.omg.CORBA.NO_PERMISSION: vmcid: 0x2000 minor code: 1806 completed: Maybe [See nested exception: java.rmi.AccessException: CORBA NO_PERMISSION 9998 Maybe; nested exception is: org.omg.CORBA.NO_PERMISSION: vmcid: 0x2000 minor code: 1806 completed: Maybe] at org.quartz.jobs.ee.ejb.EJBInvokerJob.execute(EJBInvokerJob.java:175) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:525) Caused by: java.rmi.AccessException: CORBA NO_PERMISSION 9998 Maybe; nested exception is: org.omg.CORBA.NO_PERMISSION: vmcid: 0x2000 minor code: 1806 completed: Maybe at com.sun.corba.ee.impl.javax.rmi.CORBA.Util.mapSystemException(Util.java:277) at com.sun.corba.ee.impl.javax.rmi.CORBA.Util.wrapException(Util.java:741) at com.sun.corba.ee.impl.presentation.rmi.StubInvocationHandlerImpl.privateInvoke(StubInvocationHandlerImpl.java:243) at com.sun.corba.ee.impl.presentation.rmi.StubInvocationHandlerImpl.invoke(StubInvocationHandlerImpl.java:152) at com.sun.corba.ee.impl.presentation.rmi.bcel.BCELStubBase.invoke(BCELStubBase.java:225) at org.omg.stub.javax.ejb._EJBHome_DynamicStub.getEJBMetaData(org/omg/stub/javax/ejb/_EJBHome_DynamicStub.java) at org.quartz.jobs.ee.ejb.EJBInvokerJob.execute(EJBInvokerJob.java:173) ... 2 more Caused by: org.omg.CORBA.NO_PERMISSION: vmcid: 0x2000 minor code: 1806 completed: Maybe Caused by: java.rmi.AccessException: Client is not authorized for this invocation. 2009-01-20 08:06:15,232: {DEBUG} simpl.SimpleJobFactory Producing instance of Job 'Report Generation.Income Report', class=org.quartz.jobs.ee.ejb.EJBInvokerJob 2009-01-20 08:06:15,232: {DEBUG} core.JobRunShell Calling execute on job Report Generation.Income Report JACC Policy Provider: PolicyWrapper.implies, context(TimerEJB/TimerEJB)- permission((javax.security.jacc.EJBMethodPermission TimerSessionBean getEJBMetaData,Home,)) domain that failed(ProtectionDomain (file:/TimerEJB/TimerEJB ) null java.security.Permissions@a901f8 ( (java.lang.RuntimePermission getClassLoader) (java.lang.RuntimePermission loadLibrary.*) (java.lang.RuntimePermission accessDeclaredMembers) (java.lang.RuntimePermission getProtectionDomain) (java.lang.RuntimePermission modifyThreadGroup) (java.lang.RuntimePermission stopThread) (java.lang.RuntimePermission setContextClassLoader) (java.lang.RuntimePermission queuePrintJob) (javax.management.MBeanTrustPermission register) (unresolved com.sun.corba.ee.impl.presentation.rmi.DynamicAccessPermission access null) (unresolved javax.security.jacc.EJBMethodPermission TimerSessionBean quartzTestMethod,Remote,) (unresolved javax.security.jacc.EJBMethodPermission TimerSessionBean setTimer,Remote,long) (unresolved javax.security.jacc.EJBMethodPermission TimerSessionBean giveItBack,Local,) (unresolved javax.security.jacc.EJBMethodPermission TimerSessionBean giveItBack,Remote,) (unresolved javax.security.jacc.EJBMethodPermission TimerSessionBean quartzTestMethod,Local,) (unresolved javax.security.jacc.EJBMethodPermission TimerSessionBean timeout,Remote,javax.ejb.Timer) (unresolved com.sun.enterprise.security.CORBAObjectPermission * *) (java.util.PropertyPermission line.separator read) (java.util.PropertyPermission java.vm.version read) (java.util.PropertyPermission java.vm.specification.version read) (java.util.PropertyPermission java.vm.specification.vendor read) (java.util.PropertyPermission java.vendor.url read) (java.util.PropertyPermission java.vm.name read) (java.util.PropertyPermission * read,write) (java.util.PropertyPermission os.name read) (java.util.PropertyPermission java.vm.vendor read) (java.util.PropertyPermission path.separator read) (java.util.PropertyPermission java.specification.name read) (java.util.PropertyPermission os.version read) (java.util.PropertyPermission os.arch read) (java.util.PropertyPermission java.class.version read) (java.util.PropertyPermission java.version read) (java.util.PropertyPermission file.separator read) (java.util.PropertyPermission java.vendor read) (java.util.PropertyPermission java.vm.specification.name read) (java.util.PropertyPermission java.specification.version read) (java.util.PropertyPermission java.specification.vendor read) (javax.security.auth.PrivateCredentialPermission javax.resource.spi.security.PasswordCredential * "*" read) (javax.management.MBeanPermission [com.sun.messaging.jms.*:*] *) (java.net.SocketPermission localhost:1024- listen,resolve) (java.net.SocketPermission * connect,resolve) (java.io.FilePermission C:\DOCUME~1\e01a14b2\LOCALS~1\Temp
