设置/配置EJB定时服务的数据源 [英] Set/configure the EJB Timer Service’s DataSource

问题描述

  @Stateless 
 @我的应用程序使用EJB 3.1中的定时服务LocalBean 
 public class StatelessTimerSessionBean {
 
 @Schedule（minute =*，second =0，dayOfMonth =*，month =*，year =*，小时=9-17，dayOfWeek =周一至周五）
 public void myTimer（）{
 System.out.println（Timer event：+ new Date（））; 
 
 
 
 
 $ blockquote 
 
.. set EJB定时服务的Timer DataSource设置为一个有效的JDBC资源。

启动GlassFish服务器管理控制台：通常 http：// localhost：4848  
 
 
在左侧导航至 [配置] > [server-config]> [EJB容器]  
 
 
然后单击 TAB 顶部 [EJB定时服务]  
 
 
然后用您的JDBC资源填写计时器数据源：例如。 [MySQL的普]。 （  注意：默认为 jdbc / __ TimerPool   ）
 
 
 重新启动 / li>

 4。仍然破碎？ TimerService刚刚停止工作（它曾经工作过）？
 
 
因此，经过一天完整的部署保存后，这发生在我身上。

I'm trying to use the Timer Service in EJB 3.1 in my app.
@Stateless
@LocalBean
public class StatelessTimerSessionBean {

    @Schedule(minute = "*", second = "0", dayOfMonth = "*", month = "*", year = "*", hour = "9-17", dayOfWeek = "Mon-Fri")
    public void myTimer() {
        System.out.println("Timer event: " + new Date());
    }
}



  
".. set the EJB Timer Service’s Timer DataSource setting to a valid JDBC resource.."
from EJB Timer Service

I cannot figure out how to configure the Timer Datasource correctly?

The error I get when deploying is:
SEVERE: Exception while invoking class org.glassfish.ejb.startup.EjbApplication start method
java.lang.RuntimeException: EJB Timer Service is not available
Running: glassfish-3.1.2.2
解决方案
1. Example Database Setup


I use MySQL for my database.
Create the table EJB__TIMER__TBL from {GF_HOME}/glassfish/lib/install/databases/ejbtimer_{DB_ENGINE}.sql
DB_ENGINE  = e.g MySQL:
CREATE TABLE EJB__TIMER__TBL (
    `CREATIONTIMERAW`      BIGINT        NOT NULL,
    `BLOB`                 BLOB,
    `TIMERID`              VARCHAR(255)  NOT NULL,
    `CONTAINERID`          BIGINT        NOT NULL,
    `OWNERID`              VARCHAR(255)  NULL,
    `STATE`                INTEGER       NOT NULL,
    `PKHASHCODE`           INTEGER       NOT NULL,
    `INTERVALDURATION`     BIGINT        NOT NULL,
    `INITIALEXPIRATIONRAW` BIGINT        NOT NULL,
    `LASTEXPIRATIONRAW`    BIGINT        NOT NULL,
    `SCHEDULE`             VARCHAR(255)  NULL,
    `APPLICATIONID`        BIGINT        NOT NULL,
    CONSTRAINT `PK_EJB__TIMER__TBL` PRIMARY KEY (`TIMERID`)
);


2. Server Configuration


Start your GlassFish server admin console: usually http://localhost:4848
On your left navigate to [Configurations] > [server-config] > [EJB Container]
Then click the TAB up top [EJB Timer Service]
Then fill out Timer Datasource: with your JDBC Resource eg. [mysql-pu]. (  Note: Defaults to jdbc/__TimerPool)
Restart the Server


3. The Result

...

INFO: EJB5181:Portable JNDI names for EJB TimerBean: [java:global/ejb-timer-service-app/TimerBean, java:global/ejb-timer-service-app/TimerBean!com.sun.ejb.containers.TimerLocal]
INFO: WEB0671: Loading application [ejb-timer-service-app] at [/ejb-timer-service-app]

...


4. Still Broken? TimerService just stopped working (it used to work)?

So this happened to me after a day full of "deploy on save". The TimerService was unavailable all of a sudden.
Severe:   Exception while loading the app
Severe:   Undeployment failed for context /ejb-timer-service-app
Warning:   Cannot deploy or load EJBTimerService: org.glassfish.deployment.common.DeploymentException: Error in linking security policy for ejb-timer-service-app -- Inconsistent Module State
