Description
I have some code that worked fairly well with the release version of ActiveMQ 4.1 using OpenWire. One of my colleagues upgraded the server to the latest snapshot of ActiveMQ 5, and suddenly while I could still write to the queues on that server I could no longer read from them.
Upgrading my client's jar to 5.0 cured the problem. The client was now able to read from and write to the 5.0 server. However the client and server versions should not need to be in such close sync.
For example, this simple program to write a couple of messages and then read them back fails until I change the jar archive to match the server's:
import javax.jms.*; import org.apache.activemq.*; import org.apache.activemq.command.*; public class CompletedRead { private static String url = "tcp://queue.example.com:61616"; private static String queue = "foo"; public static void main(String[] args) throws JMSException { ConnectionFactory out = new ActiveMQConnectionFactory(url); Connection connection = out.createConnection(); Destination destination = new ActiveMQQueue( queue ); connection.start(); Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); MessageProducer producer = session.createProducer(destination); TextMessage message = session.createTextMessage(); message.setText("118652"); producer.send(message); message.setText("118653"); producer.send(message); producer.close(); session.close(); connection.close(); receive(); } private static void receive() throws JMSException { ConnectionFactory in = new ActiveMQConnectionFactory(url); Connection connection = in.createConnection(); Destination destination = new ActiveMQQueue( queue ); connection.start(); Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); MessageConsumer consumer = session.createConsumer(destination); TextMessage message = (TextMessage) consumer.receive(10000); System.out.println(message.getText()); message = (TextMessage) consumer.receive(10000); System.out.println (message.getText()); consumer.close(); session.close(); connection.close(); }
