我正在尝试使用JMS和glasfish 3做一个简单消息发送者的虚拟示例。我创建了一个无状态bean，并且已在glasfish 3中定义了jsm/factory和jms/queue。是以下一个：JEE 6 JMS示例
package converter.ejb.impl;
import javax.annotation.Resource;
import javax.ejb.Stateless;
import javax.jms.*;
import java.util.Date;
@Stateless
public class SimpleMessageClientBean {
@Resource(mappedName = "jms/ConnectionFactory")
private static ConnectionFactory connectionFactory;
@Resource(mappedName = "jms/Queue")
private Queue queue;
public void sampleMessageSend(){
try {
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false,
Session.AUTO_ACKNOWLEDGE);
MessageProducer messageProducer =
session.createProducer(queue);
TextMessage jmsMessage = session.createTextMessage("Hi, this
is a 'hello world' of JMS : "+new Date());
messageProducer.send(jmsMessage);
} catch (JMSException e) {
e.printStackTrace();
}
}
}
我通过servlet调用它，调用EJB和方法sampleMessageSend。
每次我尝试调用我收到下面的异常此EJB消息：

我不明白什么是问题的根源。
