ActiveMQ 4.1.1 client can write to but not read from ActiveMQ 5.0 server
------------------------------------------------------------------------
Key: AMQ-1359
URL: https://issues.apache.org/activemq/browse/AMQ-1359
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.0.0
Reporter: Elliotte Rusty Harold
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();
}
