Question

 package jboss5.ejb3.mdb;

import java.util.HashMap;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.EJB;
import javax.ejb.EJBException;
import javax.ejb.MessageDriven;
import javax.ejb.MessageDrivenBean;
import javax.ejb.MessageDrivenContext;
import javax.ejb.TransactionManagement;
import javax.ejb.TransactionManagementType;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;
import javax.naming.InitialContext;

@MessageDriven(
    activationConfig = {
    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
    @ActivationConfigProperty(propertyName="destination", propertyValue="queue/Queue1"),
    }
    )

@TransactionManagement(TransactionManagementType.CONTAINER)
@EJB(name = "EJB3MessageDrivenLocal1", beanInterface = EJB3MessageDrivenLocal.class)

 public class EJB3MessageDrivenBean implements MessageDrivenBean, MessageListener
 {
ObjectMessage msg = null;
private MessageDrivenContext mdc = null;

public EJB3MessageDrivenBean() {}

public void setMessageDrivenContext(MessageDrivenContext mdc) {
    this.mdc = mdc;
}

public void onMessage(Message inMessage) {
        }

@Override
public void ejbRemove() throws EJBException {
    // TODO Auto-generated method stub
}
 }

上面的代码是我的消息驱动bean，适用于单个队列＆＃39; Queue1＆＃39;。现在我想将Queue2与同一个mdb相关联。我可以通过创建另一个mdb类来做同样的事情＆＃34; EJB3MessageDrivenBean2＆＃34;并且只需更改activationConfig属性，如下所示。

    @MessageDriven(
    activationConfig = {
    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
    @ActivationConfigProperty(propertyName="destination", propertyValue="queue/Queue2"),
    }
    )

但是在这个方法中我必须复制我的代码，并且将来如果我必须关联另一个队列Queue3，那么我必须再次复制java文件。

通过更改xml文件或任何其他方法的任何其他方法。

更多细节

让我们说队列1中的消息是JmsMsg11，JmsMsg12，JmsMsg13，JmsMsg14 让我们说队列2中的消息是JmsMsg21，JmsMsg22，JmsMsg23，JmsMsg24

我必须同时处理JmsMsg11和JmsMsg21。在处理JmsMsg11之后，我必须处理JmsMsg12然后处理JmsMsg13然后处理JmsMsg14。同样适用于queue2。

我通过以下代码在ejb-jar.xml和weblogic-ejb-jar.xml中进行了一些更改，在weblogic 10.x中做了同样的事情。不知道怎么做jboss 5.x. ejb-jar.xml
