JMS to PubSub to BigQuery (GCP): A Step-by-Step Guide to Integrating Messaging Systems

Are you tired of dealing with disparate messaging systems and struggling to integrate them with your data analytics pipeline? Look no further! In this article, we’ll take you through a comprehensive guide on how to integrate JMS (Java Message Service) with PubSub (Google Cloud Pub/Sub) and BigQuery (Google Cloud BigQuery) on the Google Cloud Platform (GCP). By the end of this tutorial, you’ll be able to seamlessly stream messages from JMS to PubSub and ultimately to BigQuery, unlocking the power of real-time data analytics.

Prerequisites

Before we dive into the integration process, make sure you have the following prerequisites in place:

• A GCP account with the following services enabled:
  • Google Cloud Pub/Sub
  • Google Cloud BigQuery
  • Java Message Service (JMS)
• A basic understanding of Java and Java-based messaging systems
• Familiarity with GCP services and their respective APIs

Step 1: Set up JMS

In this step, we’ll set up a basic JMS system using Apache ActiveMQ, a popular open-source messaging broker. You can choose any other JMS provider, but for simplicity, we’ll use ActiveMQ.

Download and install ActiveMQ from the official website. Once installed, create a new queue by navigating to the ActiveMQ web console and clicking on the “Queues” tab.

  Queue Name: my-jms-queue
  Queue Type: standard

Create a new Java-based producer to send messages to the queue:

  import javax.jms.Connection;
  import javax.jms.ConnectionFactory;
  import javax.jms.Destination;
  import javax.jms.Message;
  import javax.jms.MessageProducer;
  import javax.jms.Session;

  public class JMSSender {
    public static void main(String[] args) {
      ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
      Connection connection = factory.createConnection();
      connection.start();

      Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
      Destination destination = session.createQueue("my-jms-queue");
      MessageProducer producer = session.createProducer(destination);

      for (int i = 0; i < 10; i++) {
        Message message = session.createTextMessage("Hello, JMS! " + i);
        producer.send(message);
      }

      connection.close();
    }
  }

Step 2: Set up PubSub

In this step, we'll create a PubSub topic and subscription to receive messages from JMS.

Create a new PubSub topic using the GCP Console or the command-line tool:

  gcloud pubsub topics create my-pubsub-topic

Create a new PubSub subscription to receive messages from the topic:

  gcloud pubsub subscriptions create my-pubsub-subscription --topic=my-pubsub-topic

Step 3: Integrate JMS with PubSub using a Java-based Bridge

In this step, we'll create a Java-based bridge to forward messages from JMS to PubSub. We'll use the Google Cloud Pub/Sub API Client Library for Java to interact with PubSub.

Add the following dependencies to your Java project:

  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-pubsub</artifactId>
      <version>1.108.2</version>
    </dependency>
    <dependency>
      <groupId>org.apache.activemq</groupId>
      <artifactId>activemq-all</artifactId>
      <version>5.15.13</version>
    </dependency>
  </dependencies>

Implement the Java-based bridge to forward messages from JMS to PubSub:

  import com.google.cloud.pubsub.v1.AckReply;
  import com.google.cloud.pubsub.v1.Message;
  import com.google.cloud.pubsub.v1.Publisher;
  import com.google.cloud.pubsub.v1.Subscriber;
  import com.google.protobuf.ByteString;
  import com.google.pubsub.v1.ProjectSubscriptionName;
  import javax.jms.Connection;
  import javax.jms.ConnectionFactory;
  import javax.jms.Destination;
  import javax.jms.JMSException;
  import javax.jms.MessageConsumer;
  import javax.jms.Session;

  public class JMSBridge {
    public static void main(String[] args) {
      ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
      Connection connection = factory.createConnection();
      connection.start();

      Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
      Destination destination = session.createQueue("my-jms-queue");
      MessageConsumer consumer = session.createConsumer(destination);

      Publisher publisher = Publisher.newBuilder(
          ProjectSubscriptionName.format("my-project-id", "my-pubsub-subscription"))
          .setEndpoint("https://pubsub.googleapis.com/v1/")
          .build();

      while (true) {
        Message jmsMessage = consumer.receive();
        ByteString byteString = ByteString.copyFrom(jmsMessage.getBody(), "UTF-8");
        Message pubsubMessage = Message.newBuilder().setData(byteString).build();
        publisher.publish(pubsubMessage);
      }
    }
  }

Step 4: Integrate PubSub with BigQuery

In this step, we'll create a BigQuery dataset and table to store messages received from PubSub.

Create a new BigQuery dataset and table using the GCP Console or the command-line tool:

  bq mk my-bigquery-dataset
  bq mk my-bigquery-table my-bigquery-dataset
    (
      message STRING
    )

Create a new PubSub subscriber to receive messages and stream them to BigQuery:

  gcloud pubsub subscriptions create my-pubsub-subscription-bigquery --topic=my-pubsub-topic

Implement the PubSub subscriber to stream messages to BigQuery:

  import com.google.cloud.bigquery.BigQuery;
  import com.google.cloud.bigquery.BigQueryOptions;
  import com.google.cloud.bigquery.InsertAllRequest;
  import com.google.cloud.bigquery.InsertAllResponse;
  import com.google.cloud.bigquery.TableId;
  import com.google.cloud.pubsub.v1.AckReply;
  import com.google.cloud.pubsub.v1.Message;
  import com.google.cloud.pubsub.v1.Subscriber;
  import com.google.protobuf.ByteString;

  public class PubSubSubscriber {
    public static void main(String[] args) {
      BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();
      TableId tableId = TableId.of("my-bigquery-dataset", "my-bigquery-table");

      Subscriber subscriber = Subscriber.newBuilder(
          ProjectSubscriptionName.format("my-project-id", "my-pubsub-subscription-bigquery"),
          (pubsubMessage, consumer) -> {
            ByteString byteString = pubsubMessage.getData();
            String message = byteString.toStringUtf8();
            InsertAllRequest request =
                InsertAllRequest.newBuilder(tableId)
                    .addRow(message)
                    .build();
            InsertAllResponse response = bigquery.insertAll(request);
            consumer.ack();
          })
          .build();

      subscriber.startAsync().awaitRunning();
      while (true) {
        subscriber.awaitTerminated();
      }
    }
  }
