ACTIVEMQ the default listening to port 61616, check this port to see if it starts successfully.

Netstat-an|grep 61616

If all goes well, you will see the following log

By the way, log on to the admin page to see if there are any problems with wood:

Next, use a simple point-to-point test message to send and receive messages.

Message reception

Import javax.jms.Destination;
Import javax.jms.JMSException;

Import org.apache.activemq.ActiveMQConnection;

Import Org.apache.activemq.ActiveMQConnectionFactory; public class Receiver {public static void main (string[] args) throws JMSException {ConnectionFactory factor y = new Activemqconnectionfactory (Activemqconnection.default_user, Activemqconnection.default_password, "
        tcp://10.0.0.109:61616 ");
        Connection Connection = Factory.createconnection ();

        Session session = Connection.createsession (Boolean.true, Session.auto_acknowledge);
        
        Destination Destination = Session.createqueue ("Testqueue");
        Messageconsumer consumer = session.createconsumer (destination); ObjectMessage message =(objectmessage) consumer.receive ();
            if (message!= null) {String messagestring = (string) message.getobject ();
        System.out.println ("Receive:" + messagestring); }
    }

}

See console print out: Receive:hello world ..., know to receive the message, the inside flow face ah ah ah ah ...

> Close

Query process ID (PID) to prevent its process:

Ps-ef | grep activemq
kill-9 pid

Run sender again, she can't connect, hahaha haha

Exception in thread "main" javax.jms.JMSException:Could don't connect to broker url:tcp://10.0.0.109:61616. Reason:java.net.ConnectException:Connection Refused:connect

Well, the basic set-up is over.

In the process, there is a small problem, is that I started with JDK1.6 to run, reported the common unsupported Major.minor version 51.0

For this issue, this post has a very good reference meaning:

Http://www.cnblogs.com/chinafine/articles/1935748.html

Find a class in the jar and execute the following command to find out minor version, major version:

Javap-verbose YourClassName

Or view the meta-inf\manifest in the jar directly. Mf.

Then compare the JDK version in the post and replace it with JDK1.7 OK.
