The JMS Consumer class.

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;
import org.springframework.jms.core.JmsTemplate;

public class JmsMessageConsumer {

private JmsTemplate jmsTemplate;

public JmsTemplate getJmsTemplate() {
    return jmsTemplate;
}

public void setJmsTemplate(JmsTemplate jmsTemplate) {
    this.jmsTemplate = jmsTemplate;
}

public Message receiveMessage() throws JMSException {
    System.out.println("Start  : Inside JMS message Consumer");
    Message msg =(Message)getJmsTemplate().receive();
    msg.acknowledge();
    System.out.println("End  : Inside JMS message Consumer");
    return msg;
}}

The session is already closed when the receive() exits. With CLIENT_ACKNOWLEDGE, the template automatically acks the message before exiting.

Is there any way where explicitly acknowledgement can be done? – Sarvesh H Feb 02 '23 at 02:32
Not using the `receive()` method - although you can run it in a transaction and throw an exception to roll it back. You can also drop down to the lower level JMS API using a `JmsTemplate.execute()` command. – Gary Russell Feb 02 '23 at 13:30
