javax.jms.InvalidClientIDException: Broker: localhost - Client: FS_Proceduer already connected from /127.0.0.1:port

Question

How do you resolve this JMSException? Thanks!

Broker: localhost - Client: FS_Proceduer already connected

javax.jms.InvalidClientIDException: Broker: localhost - Client: FS_Proceduer already connected from /127.0.0.1:56556

This is triggered by this method:

private void connectAndInitActiveMQ() throws JMSException{
        logger.debug("It's ready to connect to jms service");
        if(null != connection){
            try{
                logger.debug("Closing connection");
                connection.close();
            }catch(Exception e){
                logger.error(e.getMessage(), e);
            }
        }
        logger.debug("Creating a new connection");

        logger.debug("Is queueConnectionFactory null? "+(queueConnectionFactory==null));

        connection = queueConnectionFactory.createConnection();

        logger.debug("Is the new connection null? "+(connection==null));

        logger.debug("Starting the new connection");
        connection.start();

        logger.debug("Connected successfully: " + connection);

        session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
        queue = session.createQueue(queueName);
        messageProducer = session.createProducer(queue);
    }

Is it the factory problem? Or some other source?

You would get this error if you configured your connections to have the same client ID. The JMS spec is explicit that only a single connection can connect to the remote with the same Client ID at any given time, resolve your configuration and things should work just fine.
