Now let”s create a consumer application which will receive message from the ActiveMQ Queue.

Create Project

Using eclipse, select File → New → Maven Project. Tick the Create a simple project(skip archetype selection) and click Next.

Enter the details, as shown below −

• groupId − com.tutorialspoint

• artifactId − consumer

• version − 0.0.1-SNAPSHOT

• name − ActiveMQ Consumer

Click on Finish button and a new project will be created.

pom.xml

Now update the content of pom.xml to include dependencies for ActiveMQ.

         </plugin>
         <plugin>

            <version>1.14</version>
            <executions>
               <execution>

                  <goals><goal>uberize</goal></goals>
               </execution>
            </executions>
         </plugin>
      </plugins>
   </build>  
</project>

Now create a Consumer class which will receive message from the ActiveMQ Queue.

package com.tutorialspoint.activemq;

import java.io.Console;

import javax.jms.Connection;
import javax.jms.Destination;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.qpid.jms.JmsConnectionFactory;

public class Consumer {
   public static void main(String[] args) throws Exception {
      // Create a connection to ActiveMQ JMS broker using AMQP protocol
      JmsConnectionFactory factory = new JmsConnectionFactory("amqp://localhost:5672");
      Connection connection = factory.createConnection("admin", "password");
      connection.start();

      // Create a session
      Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

      // Create a queue
      Destination destination = session.createQueue("MyFirstQueue");

      // Create a consumer specific to queue
      MessageConsumer consumer = session.createConsumer(destination);

      Console c = System.console();
      String response;
      do {      	
         // Receive the message
         Message msg = consumer.receive();
         response = ((TextMessage) msg).getText();

         System.out.println("Received = "+response);

      } while (!response.equalsIgnoreCase("Quit"));

      // Close the connection
      connection.close();
   }
}

Consumer class creates a connection, starts the session, creates a consumer and then receives message from queue if there is any. If queue contains quit as message then application terminates else it will keep polling queue for messages.

We”ll run this application in ActiveMQ – Test Application chapter.
