I want to use quartz in my small and simple web application. (Quartz 2.1.6 and tomcat 7.0.22). I want to change trigger cron expression without restart my application. I put jobs in xml file quartz-jobs.xml and set up XMLSchedulingDataProcessorPlugin in quartz.properties
Problem: when i change content of quartz-jobs.xml, quartz deceted file was changed and reload it, delete and create new job. I see it in log file. But content of this file is old (the same as it will on startup).
So i have in filesystem new version of quartz-jobs.xml, but quartz takes somewhere old version of that file.
Filesystem is plain ext4 with default setings.
So, how to refresh quartz jobs and triggers from xml file?
Here is my configuration:
quartz.properties:
org.quartz.scheduler.instanceName = SMSScheduler
org.quartz.threadPool.threadCount = 1
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
org.quartz.scheduler.skipUpdateCheck=true
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = quartz-jobs.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 30
org.quartz.plugin.jobInitializer.wrapInUserTransaction = false
quartz-jobs.xml
<?xml version='1.0' encoding='utf-8'?>

EDIT: reported to terracota https://jira.terracotta.org/jira/browse/QTZ-334
You should try to specify the absolute path to your quartz-jobs.xml file to avoid the issue of tomcat not reloading the files in the webapp context even when they are changed.

We built a small java project for our business needs with quartz.properties and quartz_jobs.xml with the same configuration mentioned, but without Tomcat (Java application project).
Even in the small program, after starting the Java class (scheduler.start()), modifying the quartz-jobs.xml did not trigger the cron based on the expression change.
To solve, I provided the absolute path in quartz.properties, and then the cron expression changes were picked up by the scheduler Factory.
