This tutorial will show you to how to connect a Apache Qpid JMS 1.1 client to a Solace Message Router using AMQP, add a topic subscription and publish a message matching this topic subscription. This is the publish/subscribe message exchange pattern as illustrated here:

At the end, this tutorial walks through downloading and running the sample from source.

This tutorial focuses on using a non-Solace JMS API implementation. For using the Solace JMS API see Solace Getting Started JMS Tutorials.


This tutorial assumes the following:

  • You are familiar with Solace core concepts.
  • You have access to Solace messaging with the following configuration details:

    • Connectivity information for a Solace message-VPN
    • Enabled client username and password

One simple way to get access to Solace messaging quickly is to create a messaging service in Solace Cloud as outlined here. You can find other ways to get access to Solace messaging below.


The goal of this tutorial is to demonstrate how to use a Apache Qpid JMS 1.1 over AMQP using Solace messaging. This tutorial will show you:

  1. How to build and send a message on a topic
  2. How to subscribe to a topic and receive a message

Get Solace Messaging

This tutorial requires access Solace PubSub+ messaging and requires that you know several connectivity properties about your Solace messaging. Specifically you need to know the following:

Resources Value Description
Host String This is the address clients use when connecting to the PubSub+ messaging to send and receive messages. (Format: DNS_NAME:Port or IP:Port)
Message VPN String The PubSub+ message router Message VPN that this client should connect to.
Client Username String The client username. (See Notes below)
Client Password String The client password. (See Notes below)

There are several ways you can get access to PubSub+ Messaging and find these required properties.

Option 1: Use PubSub+ Cloud

  • Follow these instructions to quickly spin up a cloud-based PubSub+ messaging service for your applications.
  • The messaging connectivity information is found in the service details in the connectivity tab (shown below). You will need:

    • Host:Port (use the SMF URI)
    • Message VPN
    • Client Username
    • Client Password

Option 2: Start a PubSub+ Software

  • Follow these instructions to start the PubSub+ Software in leading Clouds, Container Platforms or Hypervisors. The tutorials outline where to download and how to install the PubSub+ Software.

  • The messaging connectivity information are the following:

    • Host: <public_ip> (IP address assigned to the VMR in tutorial instructions)

    • Message VPN: default

    • Client Username: sampleUser (can be any value)

    • Client Password: samplePassword (can be any value)

      Note: By default, the PubSub+ Software "default" message VPN has authentication disabled.

Option 3: Get access to a PubSub+ Appliance

  • Contact your PubSub+ appliance administrators and obtain the following:

    • A PubSub+ Message-VPN where you can produce and consume direct and persistent messages
    • The host name or IP address of the Solace appliance hosting your Message-VPN
    • A username and password to access the Solace appliance

Obtaining Apache Qpid JMS

This tutorial assumes you have downloaded and successfully installed the Apache Qpid JMS client. If your environment differs from the example, then adjust the build instructions appropriately.

The easiest way to install it is through Gradle or Maven.

Java Messaging Service (JMS) Introduction

JMS is a standard API for sending and receiving messages. As such, in addition to information provided on the Solace developer portal, you may also look at some external sources for more details about JMS. The following are good places to start:


The last (Oracle docs) link points you to the JEE official tutorials which provide a good introduction to JMS.

This tutorial focuses on using JMS 1.1 (April 12, 2002), for JMS 2.0 (May 21, 2013) see Solace Getting Started AMQP JMS 2.0 Tutorials.

Connecting to Solace Messaging

In order to send or receive messages, an application must start a JMS connection.

There are three parameters for establishing the JMS connection: the Solace messaging host name with the AMQP service port number, the client username and the optional password.

ConnectionFactory connectionFactory = new JmsConnectionFactory(solaceUsername, solacePassword, solaceHost);
Connection connection = connectionFactory.createConnection();

Next, a session needs to be created. The session will be non-transacted using the acknowledge mode that automatically acknowledges a client's receipt of a message.

Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

At this point the application is connected to Solace messaging and ready to publish messages.

Publishing messages

In order to publish a message to a topic a JMS message MessageProducer needs to be created.

Diagram: Sending a Persistent Message to a Queue

final String TOPIC_NAME = "T/GettingStarted/pubsub";
Topic topic = session.createTopic(TOPIC_NAME);
MessageProducer messageProducer = session.createProducer(null);

Now we can publish the message.

TextMessage message = session.createTextMessage("Hello world!");
messageProducer.send(topic, message,

Now if you execute the program it will successfully publish a message, but another application is required to receive it.

Receiving messages

In order to receive a message from a topic a JMS MessageConsumer needs to be created.

Diagram: Receiving a Persistent Message from a Queue

final String TOPIC_NAME = "T/GettingStarted/pubsub";
Topic topic = session.createTopic(TOPIC_NAME);
MessageConsumer messageConsumer = session.createConsumer(topic);

We will be using the anonymous inner class for receiving messages asynchronously.

messageConsumer.setMessageListener(new MessageListener() {
    public void onMessage(Message message) {
        try {
            if (message instanceof TextMessage) {
                System.out.printf("TextMessage received: '%s'%n", ((TextMessage) message).getText());
            } else {
                System.out.println("Message received.");
            System.out.printf("Message Content:%n%s%n", message.toString());
            latch.countDown(); // unblock the main thread
        } catch (Exception ex) {
            System.out.println("Error processing incoming message.");

If you execute the program, it will block at the latch.await() call until a message is received. Now if you execute the program that publishes a message, the program will resume and print out the received message.


Combining the example source code shown above results in the following source code files:

Getting the Source

Clone the GitHub repository containing the Solace samples.

git clone
cd solace-samples-amqp-qpid-jms1


You can build and run both example files directly from Eclipse or with Gradle.

./gradlew assemble

The examples can be run as:

cd build/staged/bin
./topicSubscriber amqp://<HOST:AMQP_PORT> <USERNAME> <PASSWORD>
./topicPublisher amqp://<HOST:AMQP_PORT> <USERNAME> <PASSWORD>

Sample Output

First start the TopicSubscriber so that it is up and waiting for published messages. You can start multiple instances of this application, and all of them will receive published messages.

$ topicSubscriber amqp://<HOST:AMQP_PORT> <USERNAME> <PASSWORD>
TopicSubscriber is connecting to Solace messaging at amqp://<HOST:AMQP_PORT>...
Connected to the Solace messaging.
Awaiting message...

Then you can start the TopicPublisher to publish a message.

$ topicPublisher amqp://<HOST:AMQP_PORT> <USERNAME> <PASSWORD>
TopicPublisher is connecting to Solace messaging amqp://<HOST:AMQP_PORT>...
Connected to the Solace messaging.
Sending message 'Hello world!' to topic 'T/GettingStarted/pubsub'...
Sent successfully. Exiting...

Notice how the published message is received by the TopicSubscriber.

Awaiting message...
TextMessage received: 'Hello world!'
Message Content:
JmsTextMessage { org.apache.qpid.jms.provider.amqp.message.AmqpJmsTextMessageFacade@18c1752a }

With that you now know how to use the Apache Qpid JMS 1.1 over AMQP using Solace messaging to implement the publish/subscribe message exchange pattern.
