Does ActiveMQ support max message processing time in consumer

Question

I have a ActiveMQ consumer script running in Java where I am calling consumer.receive() in a while(true) loop.

I need to implement timeout for each message processed (eg: if a message process goes beyond 15 seconds I have to receive the next one).

I have given the client acknowledge mode for ACK.

Please look at the consumeMessage method where I have implemented the consume.

Desired outcome:

After 15 seconds the first message needs to be discarded (ie it should not invoke acknowledge() ). The next message needs to be processed instead.

//package consumer;

import javax.jms.DeliveryMode;
import javax.jms.Destination;
import javax.jms.ExceptionListener;
import javax.jms.JMSException;

import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;

public class ActivmqConsumer implements ExceptionListener {

    ActiveMQConnectionFactory connectionFactory = null;
    Connection connection = null;
    Session session = null;

    public ActivmqConsumer() throws Exception{
        String USERNAME = "admin";      
        String PASSWORD = "admin";
        this.connectionFactory = new ActiveMQConnectionFactory(USERNAME, PASSWORD, "tcp://192.168.56.101:61616?jms.prefetchPolicy.all=1");
        // Create a Connection
        this.connection = connectionFactory.createConnection();
        connection.start();
        connection.setExceptionListener(this);
        // Create a Session
        this.session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);
    }

    public void consumeMessage(String destinationName, EventProcesser eventprocess){
        Destination destination = null;
        MessageConsumer consumer = null;
        try{
        // Create the destination (Topic or Queue)
        destination = session.createQueue(destinationName);

        // Create a MessageConsumer from the Session to the Topic or Queue
        consumer = session.createConsumer(destination);

        // Wait for a message
        while(true){
            Message message = consumer.receive(2);
            if(message==null){
                continue;
            }
            else if(message instanceof TextMessage) {
                TextMessage textMessage = (TextMessage) message;
                String text = textMessage.getText();
                System.out.println("Received: " + text);
                eventprocess.processEvent(text);
                message.acknowledge();
            } else{
                System.out.println("Received: " + message);
            }
         }
        }catch(Exception ex){
            ex.printStackTrace();
        }finally{
            try{
            consumer.close();
            }catch(Exception ex){
                ex.printStackTrace();
            }
        }
    }
}

There is no "max message processing time" or equivalent feature in ActiveMQ. You'll need to monitor the processing yourself. Maybe take a look at this question/answer for ideas on how to do that. An alternative would be to use a JTA transaction manager and consume the message in a transaction with a timeout of 15 seconds. Using an MDB in a Java EE container would be a simple way to get the transaction timeout functionality.
