Trying to use the jakarta.jms Apache Qpid AMQP client to process messages.
I am trying to use poolable connection factory using org.messagehub.
Standlone java code works, refer the java changes.
When I try use the same in Spring XML DSL in Camel, the AMQP component doesn't support the jakarta.jmx connection factory.
Does the apache-amqp component support JMS 2.0 from Apache Qpid client yet?
package org.example;
import jakarta.jms.Connection;
import jakarta.jms.ConnectionFactory;
import jakarta.jms.DeliveryMode;
import jakarta.jms.Destination;
import jakarta.jms.ExceptionListener;
import jakarta.jms.JMSException;
import jakarta.jms.Message;
import jakarta.jms.MessageConsumer;
import jakarta.jms.MessageProducer;
import jakarta.jms.Session;
import jakarta.jms.TextMessage;
import org.apache.camel.component.jms.JmsConfiguration;
import org.messaginghub.pooled.jms.JmsPoolConnectionFactory;
import javax.naming.Context;
import javax.naming.InitialContext;
public class AMQPArtemisClient {
public static void main(String[] args) throws Exception {
try {
// The configuration for the Qpid InitialContextFactory has been supplied in
// a jndi.properties file in the classpath, which results in it being picked
// up automatically by the InitialContext constructor.
Context context = new InitialContext();
ConnectionFactory factory = (ConnectionFactory) context.lookup("myFactoryLookup");
Destination queue = (Destination) context.lookup("myQueueLookup");
System.setProperty("USER","admin");
System.setProperty("PASSWORD","admin");
//added for poolable connection
JmsPoolConnectionFactory poolConnectionFactory = new JmsPoolConnectionFactory();
poolConnectionFactory.setMaxConnections(5);
poolConnectionFactory.setConnectionFactory(factory);
// Connection connection = factory.createConnection(System.getProperty("USER"), System.getProperty("PASSWORD"));
Connection connection = poolConnectionFactory.createConnection(System.getProperty("USER"), System.getProperty("PASSWORD"));
connection.setExceptionListener(new MyExceptionListener());
connection.start();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer messageProducer = session.createProducer(queue);
MessageConsumer messageConsumer = session.createConsumer(queue);
TextMessage message = session.createTextMessage("Hello world!");
messageProducer.send(message, DeliveryMode.NON_PERSISTENT, Message.DEFAULT_PRIORITY, Message.DEFAULT_TIME_TO_LIVE);
TextMessage receivedMessage = (TextMessage) messageConsumer.receive(2000L);
if (receivedMessage != null) {
System.out.println(receivedMessage.getText());
} else {
System.out.println("No message received within the given timeout!");
}
connection.close();
} catch (Exception exp) {
System.out.println("Caught exception, exiting.");
exp.printStackTrace(System.out);
System.exit(1);
}
}
private static class MyExceptionListener implements ExceptionListener {
@Override
public void onException(JMSException exception) {
System.out.println("Connection ExceptionListener fired, exiting.");
exception.printStackTrace(System.out);
System.exit(1);
}
}
}

- Camel component I tried to configure the AMPQ component
<bean id="jmsConnectionFactory" class="org.apache.qpid.jms.JmsConnectionFactory" >
<property name="username" value="admin"/>
<property name="password" value="secret"/>
<property name="remoteURI" value="amqp://localhost:5672" />
</bean>
<bean id="jmsPooledConnectionFactory" class="org.messaginghub.pooled.jms.JmsPoolConnectionFactory" init-method="start" destroy-method="stop">
<property name="maxConnections" value="5" />
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="jmsPooledConnectionFactory" />
<property name="concurrentConsumers" value="5" />
</bean>
<!-- uses the AMQP component -->
<bean id="jms" class="org.apache.camel.component.amqp.AMQPComponent">
<property name="configuration" ref="jmsConfig" />
<property name="connectionFactory" ref="jmsPooledConnectionFactory"/>
</bean>
When I try configuration like below I get exception jakarta.jms exception where it expects javax.jms, for now i had to lower the version of messaging hub to 2.0.5 and use qpid-jms-client jar to 1.6.0.
<bean id="amqp" class="org.apache.camel.component.amqp.AmqpComponent">
<property name="connectionFactory">
<bean class="org.apache.qpid.jms.JmsConnectionFactory" factory-method="createFromURL">
<property name="remoteURI" value="amqp://localhost:5672" />
<property name="topicPrefix" value="topic://" /> <!-- only necessary when connecting to ActiveMQ over AMQP 1.0 -->

</property>
