Glassfish计划(计时器)例外

Question

我正在尝试在Glassfish 4和java EE7上重复本教程.所以我用Netbeans中的maven创建了简单的WebApp.

我创建了简单的类:

import java.util.Date;
import javax.ejb.Schedule;
import javax.ejb.Stateless;

@Stateless
public class NewClass {

    @Schedule(minute = "*/1", hour = "*",persistent = false) 
    public void anyMethod() {
        System.out.println("hello "+new Date());
    }
}

但是,当我向应用程序deploing应用程序时,我得到此异常:

为什么EJB计时器服务不可用？我该如何启用它？:)

Answer 1

我也有同样的问题,但@ wumbrath的回答没有用.如果是这种情况 - 请先尝试回答 - 删除以下文件:

applications/ejb-timer-service-app
generated/ejb/ejb-timer-service-app
generated/jsp/ejb-timer-service-app
generated/policy/ejb-timer-service-app
generated/ejb-timer-service-app
lib/databases/ejbtimer

当然,重启服务器.

Answer 2

如果您使用嵌入式 glassfish，它可能会被禁用，您应该尝试下载独立的 glassfish，然后重试。

关于配置，您可以验证 glassfish 管理控制台中的设置，通常可以通过以下位置访问http://localhost:4848：

以下设置是相关的：

• 配置 -> 服务器配置 -> EJB 容器 -> EJB 计时器服务选项卡
• 资源 -> JDBC -> JDBC 连接池 -> __TimerPool（这里您还可以通过 Ping 按钮测试连接）
