Activemq custom authentication

1. Clone repository

2. Install service for authentication

2.1 If you want to use Rails test service

Be sure, that you have installed rails environment

  • cd ruby-auth-service
  • bundle install

(run only once, next time is not necessary)

  • rails server

Check, that service works

Should be {"notice":"Login OK"}

There are only pairs admin/admin and userName/password are valid.

2.2 If you want to use C# test service

  • open csharp-auth-service, run service with Visual Studio
  • open TestLoginForm.html in csharp-auth-service/AuthActiveMQService and send form, result should contains "Login OK"

3. Install ActiveMQ

  • Download & unzip activemq 5.10.0
  • Create backup copy of ${ACTIVEMQ_HOME}/conf/activemq.xml

4. Modify config

  • Modify ${ACTIVEMQ_HOME}/conf/activemq.xml Add to tag broker tag plugins with content below
<plugins>
    <bean id="authenticationPlugin" xmlns="http://www.springframework.org/schema/beans"
            class="com.hill30.activemq.auth.RestAuthenticationPlugin">
        <property name="authServiceUrl">
            <value>http://localhost:1141/api/auth</value>
        </property>
    </bean>
</plugins>
  • NOTE 1: Visual Studio starts app at other port, change it appropriately
  • NOTE 2: for ruby service url should be
    <value>http://localhost:3000/auth/auth/</value>
  • Edit url for service appropriate to your service

5. Compile & install authentication plugin

To compile from source:

  • cd plugin
  • mvn install
  • cp target/activemq-rest-auth.jar ${ACTIVEMQ_HOME}/lib/

OR just copy already compiled plugin from plugin/activemq-rest-auth.jar to ${ACTIVEMQ_HOME}/lib/

  • ${ACTIVEMQ_HOME}/bin/activemq start

6. Check sending messages

  • tail -n 100 -f ${ACTIVEMQ_HOME}/data/activemq.log Output should looks like

    2014-11-25 08:24:23,646 | INFO | Connector ws started | org.apache.activemq.broker.TransportConnector | main 2014-11-25 08:24:23,650 | INFO | Apache ActiveMQ 5.10.0 (localhost, ID:npakudin-mac.local-62876-1416889463309-0:1) started | org.apache.activemq.broker.BrokerService | main 2014-11-25 08:24:23,653 | INFO | For help or more information please see: http://activemq.apache.org | org.apache.activemq.broker.BrokerService | main 2014-11-25 08:24:23,656 | WARN | Store limit is 102400 mb (current store usage is 0 mb).

This command displays the contents of activemq.log and do not stop when end of file is reached, but rather to wait for additional data to be appended to the input.

  • Open http://localhost:8161/admin/topics.jsp
  • Select topic "ServiceTracker.Inbound.userName" (if not exists, connect Android application - it will create it) and press link "Send To"
  • Press Send button
  • Check, that counter Messages Enqueued increased

7. Check Android application connection

  • Run Android app (if it was run before, clear data and run again)

  • Enter url of your ActiveMQ listener, e.g. tcp://192.168.0.100:1883

  • Open http://localhost:8161/admin/topics.jsp and send message to topic "ServiceTracker.Inbound.userName". Message body shoud be valid JSON, e.g.

    {}

Check, that Android app shows the message

  • Press to that message, enter any data to any field and press Save
  • Check, that topic ServiceTracker.Outbound appeared in ActiveMQ admin console and it's counter Messages Enqueued increased

P.S. How to send persistent message from NMS with QoS = EXACTLY_ONCE

MQTT connector for ActiveMQ contains the code below

QoS qoS;
if (message.propertyExists(QOS_PROPERTY_NAME)) {
    int ordinal = message.getIntProperty(QOS_PROPERTY_NAME);
    qoS = QoS.values()[ordinal];

} else {
    qoS = message.isPersistent() ? QoS.AT_MOST_ONCE : QoS.AT_LEAST_ONCE;
}

To send persistent message from NMS with QoS = EXACTLY_ONCE is enough to set QoS for each message. If you use NMS:

For ActiveMQ 5.10

msg.Properties.SetInt("ActiveMQ.MQTT.QoS", 2); // 2 - EXACTLY_ONCE

For ActiveMQ 5.9

msg.Properties.SetInt("QoSPropertyName", 2); // 2 - EXACTLY_ONCE

It's impossible to do it with ActiveMQ web console.
