There is a new component in the ECM platform: a scheduler that can
trigger core events at designated times.
The times specification is the same as the one used by the Unix cron
program, and therefore quite flexible, see
http://quartz.sourceforge.net/javadoc/org/quartz/CronTrigger.html
The component is named org.nuxeo.ecm.platform.scheduler.core and
lives at
http://svn.nuxeo.org/nuxeo/org.nuxeo.ecm.platform.scheduler/trunk/core
A unit test shows how to do the configuration (see test/resources/
test-nxscheduler.xml), basically you have to use an extension point
and say for instance:
<schedule id="testing">
<username>Administrator</username>
<password>Administrator</password>
<eventId>testEvent</eventId>
<eventCategory>default</eventCategory>
<!-- every second -->
<cronExpression>*/1 * * * * ?</cronExpression>
</schedule>
There is also a core listener example that shows how to reconnect to
a CoreSession and from there get the document root. This is possible
because the scheduler recreates a UserSession before sending the
regular core event.
This depends on a trunk version of org.nuxeo.ecm.core.repository (to
get a proper service registration of the CoreSession).
