JEE Glassfish @schedule doesn't work

Question

I am first time using @Schedule in a stateless bean and for some reason it does not get executed by Glassfish though Glassfish says it was successfully deployed. My Java version is 1.8.0_91 Glassfish version 4.1.1

I simplified the code more and more so right now my code is the one below at the bottom with the key line being: @Schedule(second="0", minute=" ", hour=" ")

I am using jdbc/__TimerPool as JDBC resource in Glassfish and can successfully execute a ping for __TimerPool.

In my logs for Glassfish startup I found a stacktrace: java.lang.NullPointerException which is very similar (first lines are the same as an open defect of Glassfish/Eclipse ( https://java.net/jira/browse/GLASSFISH-21468 ) which according to what i read there is minor and thus should not prevent scheduing from working.

Anybody an idea whats wrong and how I can make this work?

Cheers thorsten

here the stacktrace:

here my bean:

import javax.ejb.Stateless;
import javax.ejb.Schedule;

@Stateless
public class PrintCenter implements PrintCenterRemote {
    public PrintCenter() {
        // TODO Auto-generated constructor stub
    }

    @Schedule(second="0", minute="*", hour="*")
    public void run(){
        System.out.println("Test");

    }
}

Answer 1

尝试将PrintCenter用作具有@ Startup @ Singleton批注的bean。

Answer 2

I found the solution. I need to start the domain in debug mode otherwise system.out.println is not put to server.log file :-)
