Internal

• EJB Annotations
• EJB Timer Service

Overview

Used by EJB to designate timeout callback methods that will be invoked by automatically-created timers.

Example:

@Schedule(hour="3", dayOfMonth="1", info="something")
public void toBeExecutedAt3AMOnTheFirstDayOfTheMonth() {
   ...
}

Configuration

The annotation is configured using a cron-like time expression, using the following attributes:

• second (if not specified, default is 0)
• minute (if not specified, default is 0)
• hour (if not specified, default is 0)
• dayOfMonth
• month
• dayOfWeek
• year

{{{1}}}

The following example fires a timer every 20 seconds, continuously:

@Schedule(hour="*", minute="*", second = "0/20")
public void fireEvery20SecsContinously() {
   ...
}
