    <p>Scheduler tasks should be placed only in Global class. Create two tasks, schedule only once first with <code>initialDelay</code> = 0 milliseconds.</p> <p>For the second task, you need to calculate seconds between current DateTime and next planned occurrence (ie. tomorrow at 8:00 o'clock) using common date/time classes, then set this difference as <code>initialDelay</code> and also set <code>frequency</code> to 24 hours.</p> <p>In result, it will start at the application start and will schedule the task for execution each day at required hour.</p> <p><strong>Edit</strong></p> <p>There's complete sample, (save/edit the class: <code>/app/Global.java</code>):</p> <pre><code>import akka.util.Duration; import org.joda.time.DateTime; import org.joda.time.Seconds; import play.Application; import play.GlobalSettings; import play.Logger; import play.libs.Akka; import java.util.concurrent.TimeUnit; public class Global extends GlobalSettings { @Override public void onStart(Application application) { Akka.system().scheduler().scheduleOnce( Duration.create(0, TimeUnit.MILLISECONDS), new Runnable() { @Override public void run() { Logger.info("ON START --- " + System.currentTimeMillis()); } } ); Akka.system().scheduler().schedule( Duration.create(nextExecutionInSeconds(8, 0), TimeUnit.SECONDS), Duration.create(24, TimeUnit.HOURS), new Runnable() { @Override public void run() { Logger.info("EVERY DAY AT 8:00 --- " + System.currentTimeMillis()); } } ); } public static int nextExecutionInSeconds(int hour, int minute){ return Seconds.secondsBetween( new DateTime(), nextExecution(hour, minute) ).getSeconds(); } public static DateTime nextExecution(int hour, int minute){ DateTime next = new DateTime() .withHourOfDay(hour) .withMinuteOfHour(minute) .withSecondOfMinute(0) .withMillisOfSecond(0); return (next.isBeforeNow()) ? next.plusHours(24) : next; } } </code></pre>

    1. COevery time I call http://localhost:9000 the task works again. So it means it is going to work when every user make a request. Is it not possible to start task one at the time app starts? I created the instance of Global class in controller class in index() method as Global gl=new Global(); gl.onStart(null);

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
