Question

我正在尝试在Glassfish 4和java EE7上重复this tutorial。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());
    }
}

但是当我将app下载到服务器时，我得到了这个例外：

Severe:   Exception while loading the app

为什么EJB Timer Service不可用？我该如何启用它？：）

Answer 1

我也有同样的问题，但@ wumbrath的回答并不奏效。如果是这种情况 - 请先尝试该答案 - 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

如果您使用的是嵌入式玻璃鱼，可能会被禁用，您应该尝试下载独立的玻璃鱼并再试一次。

关于配置，您可以验证glassfish管理控制台中的设置，通常可以在http://localhost:4848处找到：

以下设置是相关的：

配置 - ＆gt; server-config - ＆gt; EJB容器 - ＆gt; EJB计时器服务选项卡
资源 - ＆gt; JDBC - ＆gt; JDBC连接池 - ＆gt; __TimerPool（这里你也可以通过Ping按钮测试连接）

Answer 3

转到安装glassfish：

mv glassfish/glassfish-4.1.1/glassfish/domains/domain1
rm -rf applications/ejb-timer-service-app/
rm -rf generated/ejb/ejb-timer-service-app/
rm -rf generated/jsp/ejb-timer-service-app/
rm -rf generated/policy/ejb-timer-service-app/
rm -rf generated/ejb-timer-service-app 
rm -rf lib/databases/ejbtimer/
