I started a project in java with ActiveMQ 5.17.0. Therefore I have downloaded ActiveMQ and opened my terminal from the folder bin and execute ./activemq start.

I received:

INFO: Loading '/Users/NAME/Downloads/apache-activemq-5.17.0//bin/env'
INFO: Using java '/usr/bin/java'
INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details
./activemq: line 343: [: : integer expression expected
INFO: pidfile created : '/Users/NAME/Downloads/apache-activemq-5.17.0//data/activemq.pid' (pid '3084')

As I have seen in other posts, this is the expected result.

A part of my Java Code is:

public static void main(String[] args) {
    ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:8161"); // ActiveMQ-specific
    Connection con = null;
    try {
        con = factory.createConnection();
        Session session = con.createSession(false, Session.AUTO_ACKNOWLEDGE); // non-transacted session

        Queue queue = session.createQueue("test.queue"); // only specifies queue name

        MessageProducer producer = session.createProducer(queue);
        Message msg = session.createTextMessage("hello queue"); // text message
        producer.send(msg);

    } catch (JMSException e) {
        e.printStackTrace();
    } finally {
        if (con != null) {
            try {
                con.close(); // free all resources
            } catch (JMSException e) { /* Ignore */ }
        }
    }
}

As soon as I try to open the website https://localhost:8161/admin/admin I receive the response that Safari, Chrome, and Firefox do not get connection to localhost.

Anybody any suggestions what to do?

I have already tried to download again, different browsers, start and stop the server several times.

CodePudding user response：

1. The URL for the admin UI should be http: http://localhost:8161/admin or http://127.0.0.1:8161/admin/

2. The script activemq fails parsing the output of java -version. Maybe set the line VERSION= to your java version (e.g. VERSION=17 for java 17) to check if that is the issue.

CodePudding user response：

Your code sample shows that you are attempting to send messages to the Web UI URL vs the JMS protocol port.

Try changing your code to use port '61616':

        ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616); // ActiveMQ-specific

For the web browser access, try starting with the non-SSL url: http://localhost:8161/admin/admin instead of 'https'.
