quartz.xml
Quartz is used in AquaLogic Commerce Services to execute scheduled jobs (for example,
building the Lucene index). A quartz.xml file is used to configure quartz jobs for the different
AquaLogic Commerce Services applications. The quartz.xml file is located in the following
application-specific paths.
• Storefront – <ALCS_APP_HOME>\commerceServices\WEB-INF\conf\spring\scheduling\
• Commerce Manager – <ALCS_APP_HOME>\commerceServicesManager\WEB-
INF\conf\spring\scheduling\
• Connect – <ALCS_APP_HOME>\commerceServicesConnect\WEB-
INF\conf\spring\scheduling\
Quartz files have three basic types of blocks of XML:
• Factory block – The definition of the Scheduler Factory, which is used to populate a
Scheduler class with the list of Triggers that it will be responsible for executing.
• Job block – The definition of the job that is being scheduled. This defines the method that
will be called by the Trigger and references the class in which the method lives.
• Trigger block – The definition of the trigger that will be used to trigger the job. This will
usually be either a SimpleTriggerBean (which runs a job every x milliseconds) or a
CronTriggerBean (which will run a job at a specified time).
There is usually one Factory definition in a quartz.xml file, and then each job has both a Job
definition and a Trigger definition.

Quartz Cron Configuration
The time/trigger to execute the scheduled job can be set with the cronExpression property. The
cron expression contains six required components and one optional component. A cron
expression is written on a single line and each component is separated from the next by space.
Only the last, or rightmost, component is optional. The table below describes the cron
components in detail.
