Hi, I have a building block which sets up a Quartz job to send out emails every morning. The job is fired three times every morning instead of once. We have a hosted instance of Blackboard, which I am told runs on three virtual servers. I am guessing this is what is causing the problem, as the building block was previously working fine ...
Our use of Quartz so far has been to configure the database backed scheduler and any jobs/triggers in the spring config which is then loaded when the app is run on the cluster. Each server in the cluster then shares the triggers so that the triggers are only run by one of the servers each time. I now want to dynamically create new trigg...

Hi everyone I'm using Quartz in my .NET application. At first, I was using it in a windows service but it didn't work, so I moved it to a normal project to test it.

Hi, I have 2 instances which implements 2 different instance IDs in 2 different windows services as: //windows service 1 instance 1 properties["quartz.scheduler.instanceName"] = "instanceName1"; properties["quartz.scheduler.instanceId"] = "instanceID1"; //windows service 2 instance 2 properties["quartz.scheduler.instanceName"] = "inst...
Simple question, I think. I have org.springframework.scheduling.quartz.CronTriggerBean triggering one job once a day. Because this method can last a long time (over 24 hours), will the next day at the same time a new job be executed if the last one is not ended yet? If yes - is it possible to turn off executing new jobs until the last ...
Anybody have experience or thoughts on a scheduler to couple with a persistent Gearman queue? Obviously there's crontab available, but i'd like some more functionality. We're looking at Java Quartz. Please weigh in if you've done this before in any capacity! ...
I have chosen nearly 200 files to write on a position automatically on a particular time. Created a separate job names in Quartz scheduler. The job will be triggered on a time.

Hi, I have multiple quartz cron jobs in a load balanced environment. Currently these jobs are running on each node, which is not desirable. I want a node to run only a particular scheduler and if the node crashes, another node should run the scheduler intended for the node that crashed. How can this be done with spring 2.5.6/tomcat load ...
Hi everyone, I would like to implement asynchronous email sending in my web application when users register for a new account. This is so that if there is a problem or delay in sending the email message (e.g. the mail server is down or the network connection to the mail server is slow) the user won't be kept waiting for the sending to c...
HI, I recently installed tomcat 6.024 on windows 2008 R2 to run a java app.The app uses quartz-1.6.5 to schedule some jobs that need to run 3 times a day. The server freezes every now and then and have to reboot the machine. The catalina log displays the following when I shut down tomcat: SEVERE: A web application appears to have start...
I have a question in scheduling jobs in web application. If we have to schedule jobs in web application we can either use java util Timer/TimerTask or Quartz(there are also other scheduling mechanism, but I considered Quartz). I was considering which one to use, when i hit the site http://oreilly.com/pub/a/java/archive/quartz.html?page=1...

This should be really easy. I'm using Quartz running under Apache Tomcat 6.0.18, and I have a jobs.xml file which sets up my scheduled job that runs every minute. What I would like to do, is if the job is still running when the next trigger time rolls around, I don't want to start a new job, so I can let the old instance complete. Is t...
Where is the documentation for quartz xml files (specifically jobs.xml)? I found the javadoc online, but I can't seem to find the documentation for how to write an xml file, just some brief examples e.g. this one from O'Reilly. edit: apparently the java class that reads the jobs.xml is JobInitializationPlugin, but I don't see the docs f...
