GreenVulcano^® ESB uses this element to define a group of Timer Tasks.

The Triggers Element is used by: RSHTask, ServiceCallerTask, ShellTask and TestTask.

Might contain the following subelements:

A Trigger that is used to fire a Task at a given moment in time, and optionally repeated at a specified interval.

The following table shows the SimpleTriggerBuilder element's attributes:

Attribute	Type	Description
type	fixed	This attribute must assume the value cron-trigger
class	fixed	This attribute must assume the value it.greenvulcano.scheduler.util.quartz.impl.trigger.SimpleTriggerBuilder
name	required	Trigger name
startTime	optional	Trigger starting time in ISO format: yyyy-MM-dd HH:mm:ss
endTime	optional	Trigger ending time in ISO format: yyyy-MM-dd HH:mm:ss. If not defined is the server starting time rounded to the next minute.
repeatInterval	optional	The period of repetition of the trigger, in ms. If not defined the task is executed only once.
repeatCount	optional	The number of repetitions of the trigger. If not defined the task is executed only once. If 'period' == -1, the task is repeated endlessly (or to 'endTime').
timeZone	optional	Trigger TimeZone. If not defined is used the TimeZone defined for DateUtils.
calendarName	optional	Associate the Calendar with the given name with this Trigger.

Might contain the following sub-elements:

This element defines additional properties of the Trigger.

Might contain the following sub-elements:

This element represents a Trigger that is used to fire a Task based upon repeating calendar time intervals.

The following table shows the DateIntervalTriggerBuilder element's attributes:

Attribute	Type	Description
type	fixed	This attribute must assume the value cron-trigger
class	fixed	This attribute must assume the value it.greenvulcano.scheduler.util.quartz.impl.trigger.DateIntervalTriggerBuilder
name	required	Trigger name.
startTime	optional	Trigger starting time in ISO format: yyyy-MM-dd HH:mm:ss If not defined is the server starting time rounded to the next minute.
endTime	optional	Trigger ending time in ISO format: yyyy-MM-dd HH:mm:ss
repeatIntervalUnit	optional	The period of repetition of the trigger, in time unit. The attribute admitted values are: SECOND MINUTE HOUR DAY WEEK MONTH YEAR
repeatInterval	optional	The number of repeatIntervalUnit for repetitions of the trigger. If not defined the default is 1.
timeZone	optional	Trigger TimeZone. If not defined is used the TimeZone defined for DateUtils.
calendarName	optional	Associate the Calendar with the given name with this Trigger.

Might contain the following sub-elements:

This element represents a Trigger that is used to fire a Task at given moments in time, defined with Unix cron-like definitions.

The following table shows the CronTriggerBuilder element's attributes:

Attribute	Type	Description
type	fixed	This attribute must assume the value cron-trigger
class	fixed	This attribute must assume the value it.greenvulcano.scheduler.util.quartz.impl.trigger.CronTriggerBuilder
name	required	Trigger name.
cronExpression	required	Defines a cron expression. Reference: http://www.quartz-scheduler.org/documentation/quartz-1.x/tutorials/crontrigger
startTime	optional	Trigger starting time in ISO format: yyyy-MM-dd HH:mm:ss If not defined is the server starting time rounded to the next minute.
endTime	optional	Trigger ending time in ISO format: yyyy-MM-dd HH:mm:ss
timeZone	optional	Trigger TimeZone. If not defined is used the TimeZone defined for DateUtils.
calendarName	optional	Associate the Calendar with the given name with this Trigger.
