我有两个tomee实例聚集.
每个人都有一个注释方法
@Schedule(dayOfWeek = "*")
public void runMeDaily() {...}
我想每天只运行一次这种方法.一天不两次(每个实例一个)
我可以使用此处描述的标志仅在一个WebLogic群集节点上运行@Scheduled任务？或者只选择一些节点,但我想知道是否有更优雅的方式来做到这一点.
这个问题与集群环境中的EJB3.1 @Schedule有些相关,但我没有使用JBOSS.(而且没有回答)
在我的服务器日志中,我偶尔可以看到例外:
Aug 11, 2015 10:13:34 AM org.apache.activemq.broker.TransportConnection serviceTransportException
WARNING: Transport Connection to: tcp://127.0.0.1:55472 failed: java.io.EOFException
那些似乎不是实际事件或消息发送到队列.它们只是随机发生的.
这是Tomcat/Tomee上的ActiveMQ
配置ActiveMQ的代码是:
我的ActiveMQ配置非常简单:
<?xml version="1.0" encoding="UTF-8"?>
<tomee>
<!-- see http://tomee.apache.org/containers-and-resources.html -->
<!-- activate next line to be able to deploy applications in apps -->
<!-- <Deployments dir="apps" /> -->
<Resource id="MyJmsResourceAdapter" type="ActiveMQResourceAdapter">
BrokerXmlConfig = broker:(tcp://localhost:61616)
ServerUrl = tcp://localhost:61616
</Resource>
<Resource id="MyJmsConnectionFactory" type="javax.jms.ConnectionFactory">
ResourceAdapter = MyJmsResourceAdapter
</Resource>
</tomee>
要定义队列我有一个简单的代码:
@Resource(name = "myQueue")
private Queue barQueue;
@Resource
private ConnectionFactory connectionFactory;
/**
* Push Message to Queue …我正在使用tomee服务器来运行我的javaEE应用程序.我写了一个注入对象的过滤器.但是,该对象似乎没有实例化:
以下是我的代码:
Filter.java
@Priority(value = 2)
@Provider
@Singleton
public class Filter implements ContainerRequestFilter {
@Inject
private Faculty faculty;
public void filter(ContainerRequestContext requestContext) {
System.out.println("faculty name is :"+faculty.getFacultyName());
}
}
Faculty.java
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
public class Faculty {
private List<String> facultyMembers;
private String facultyName;
@PostConstruct
public void initialize() {
this.facultyMembers = new ArrayList<String>();
facultyMembers.add("Ian Schultz");
facultyMembers.add("Diane Reyes");
facultyName = "Computer Science";
}
public List<String> getFacultyMembers() {
return facultyMembers;
}
public String getFacultyName() {
return facultyName;
}
}
我正在获得NPE.以下是堆栈跟踪: …
我下载了最新的TomEE Plume 1.7.4版本,并尝试从IntelliJ IDEA 14内部启动它,看起来我是一个正常的服务器设置,我收到超时错误,并重复打印以下错误消息:
2016年4月11日上午9:20:31 org.apache.openejb.server.ejbd.EjbDaemon服务WARNUNG:"null OEJP/4.7"FAIL"安全错误 - [Ljava.net.URI;未列入白名单,因为可以取消预防,之前已被阻止加载它." - 调试StackTrace
我可以从普通的shell启动服务器,所以似乎与IDE有关.有谁知道问题是什么？
我正在转换Web应用程序以使用TomEE而不是Jboss 5.1.0并看到以下异常:

我的应用程序运行TomEE 7.0.0-SNAPSHOT webprofile.
当这些任务访问数据库时,他们需要一个事务.但是,Runnable/ Callableno事务内部是活动的.
ManagedScheduledExecutorService的文档说明了这一点
如果需要事务,请使用javax.transaction.UserTransaction实例.通过使用Resource注释请求注入UserTransaction对象,可以使用UserTransaction实例(...).
但是,注入了
@Resource
private UserTransaction userTransaction;
是null在调用任务时.
我采用的另一种方法是将无状态EJB注入到我的任务中,希望这会为我创建一个事务.
这导致启动时出现以下异常:

但是使用JAX-RS客户端(或cxf webclient)总是使用Johnzon,即使我将Jackson提供给Webclient.create方法也是如此.经过一些调试后,我确信TomEE会以某种方式将Johnzon添加到客户端工厂,并且不能使用其他的json消息体解析器.
这是TomEE CXF集成的错误还是我错过了什么？
当内存不足[OOME]错误时，如何配置Tomcat自动重新启动。
