将EJB Jar部署到Glassfish时发生java异常

2 周，6 日 Questions & Answers 7134

这是我第一次尝试使用JMS。我已经成功创建/部署了一个war文件，其中包含一个servlet，我可以使用它上传文件。上载文件时，它会向JMS队列发送一条消息。接下来，我编写了一个侦听器来从队列中检索上载的消息，但当我尝试部署它时，我遇到以下错误：

SEVERE: Invalid ejb jar [file-listener-ejb-1.0.jar]: it contains zero ejb. 
Note: 
1. A valid ejb jar requires at least one session, entity (1.x/2.x style), or message-  driven bean. 
2. EJB3+ entity beans (@Entity) are POJOs and please package them as library jar. 
3. If the jar file contains valid EJBs which are annotated with EJB component level annotations (@Stateless, @Stateful, @MessageDriven, @Singleton), please check server.log to see whether the annotations were processed properly.

这是一个非常简单的项目，只有一个类，使用Maven构建。该类如下所示：

package my.package;

import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@MessageDriven(mappedName = "jms/FileUploadedQueue", activationConfig = {
        @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
        @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") })
public class FileListener implements MessageListener
{
    private static Logger log = LoggerFactory.getLogger(FileListener.class);

    public FileListener()
    {
        // empty constructor
    }

    public void onMessage(Message message)
    {
        try
        {
            log.info("Received message: " + ((TextMessage)message).getText());
        }
        catch (JMSException ex)
        {
            String error = "Received error code '"
                    + ex.getErrorCode()
                    + "' retrieving message from queue jms/FileUploadedQueue.";

            Exception linkedEx = ex.getLinkedException();

            if (linkedEx != null)
            {
                log.error(error += "Linked exception: ", linkedEx);
            }
            else
            {
                log.error(error, linkedEx);
            }
        }
    }
}

我的pom。xml如下所示：

这构建了一个jar文件，当我尝试部署到Glassfish 3.1服务器（通过管理控制台）时，会导致上述错误

因为我的类上有@MessageDriven注释，所以我不确定我做错了什么。不幸的是，服务器。日志文件不包含有关错误的任何详细信息

我是否应该将jar打包到ear中并部署它

------编辑----------

我创建了一个包含ejb jar的ear，当我将ear部署到Glassfish时，我得到了相同的错误。所以，我认为这一定与注释有关。但是，我看过多个示例/教程，看不出有什么不对

欢迎提出任何见解/建议
