Question

我试图用JMS和glasfish 3做一个简单的消息发送者的虚拟示例。我创建了一个无状态bean，我在glasfish 3中定义了jsm / factory和jms / queue。代码bean是以下一个：

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。

每次我尝试调用此EJB消息时，都会收到以下异常：

我不明白问题的根源是什么。

Answer 1

抱歉。我的错误。我将glassfish中的队列定义为工厂。我有两个连接工厂，没有队列。我已经定义了一个资源命运和一个连接工厂，一切都很好。我的错。

另一方面，我不得不将队列从'jms / queue'重命名为'testQueue'。似乎'jms / queue'不是一个好名字。我想这是一个字符'/'的问题。是否有关于JMS中队列名称和连接工厂的语法规则？
