TIBCO Sink Connector for Confluent Platform

The Kafka Connect TIBCO Sink connector is used to move messages from Kafka to TIBCO Enterprise Messaging Service (EMS).


If you are required to use the Java Naming and Directory Interface™ (JNDI) to connect to TIBCO EMS, there is a general JMS Sink connector for Confluent Platform available that uses a JNDI-based mechanism to connect to the JMS broker.


The TIBCO Sink connector includes the following features:

At least once delivery

This connector guarantees that records are delivered to the Kafka topic at least once. If the connector restarts, there may be some duplicate records in the Kafka topic.

Dead Letter Queue

This connector supports the Dead Letter Queue (DLQ) functionality. For information about accessing and using the DLQ, see Confluent Platform Dead Letter Queue.

Multiple tasks

The TIBCO Sink connector supports running one or more tasks. You can specify the number of tasks in the tasks.max configuration parameter. This can lead to performance gains when multiple files need to be parsed.

JMS message format

The format of outgoing JMS message values is configured with the jms.message.format property, using one of the following options:

string (default)

When using the string message format, record values are run through Values.convertToString(...) from the Connect Data package and produced as a JMS TextMessage.

Primitive values are converted to their string equivalent and structured objects are transformed to a sensible string representation that is similar to the JSON representation, with the exception of simple string values (not in objects or arrays) which are unquoted.

Note that Single Message Transformation can be used with the configured jms.message.format to transform the record value to the desired string representation before the connector processes each record.


Record values are serialized without the Avro schema information and produced as a JMS BytesMessage. JMS consumers must have the schema to deserialize the data.

It it is important to note that the connector attempts to infer the Avro schema for records that have no schema. If the connector cannot infer the schema, the task is killed. If you are processing data without a schema, consider using one of the other jms.message.format configurations.


Record values are converted to a UTF-8 encoded JSON representation and produced as a JMS TextMessage.


Record values are passed along in bytes form without any conversion. Note that record values must be converted to bytes form before the connector processes them. Configure the value.converter property to org.apache.kafka.connect.converters.ByteArrayConverter to ensure the record values arrive in byte format.

Forward Kafka properties to JMS

The connector can be configured to forward various values from the Kafka record to the JMS Message.

  • Enable jms.forward.kafka.key to convert the record’s key to a string and forward it as the JMSCorrelationID.
  • Enable jms.forward.kafka.metadata to forward the record’s topic, partition, and offset on JMS Message properties.
    • Kafka topic is applied to the message as a string property named KAFKA_TOPIC.
    • Partition is applied to the message as an Int property named KAFKA_PARTITION.
    • Offset is applied to the message as a Long property named KAFKA_OFFSET.
  • Enable jms.forward.kafka.headers to add each header from the SinkRecord to the JMS Message as a string property.


The connector converts the record key and headers to a sensible string representation that is similar to the JSON representation, with the exception of simple string values (not in objects or arrays), which are unquoted. No other conversion is done to the key and headers before forwarding them on to the JMS Message. If another format is needed, out-of-the-box or custom Single Message Transformation can be used with the connector to transform the record keys and/or headers to the desired string representation before the JMS sink connector processes each record.


You can use this connector for a 30-day trial period without a license key.

After 30 days, you must purchase a connector subscription which includes Confluent enterprise license keys to subscribers, along with enterprise-level support for Confluent Platform and your connectors. If you are a subscriber, you can contact Confluent Support at support@confluent.io for more information.

For license properties, see Confluent Platform license, and for information about the license topic, refer to License topic configuration.

Configuration properties

Install the TIBCO Sink connector

You can install this connector by using the confluent connect plugin install command, or by manually downloading the ZIP file.


  • You must install the connector on every machine where Connect will run.
  • Kafka Broker: Confluent Platform 3.3.0 or later, or Kafka 0.11.0 or later.
  • Connect: Confluent Platform 4.1.0 or later, or Kafka 1.1.0 or later (requires header support in Connect).
  • TIBCO EMS with JMS 1.1 support.
  • tibjms Client Library. For more details, see Installing TIBCO JMS client library.
  • Java 8+. Note that Java 8 is deprecated in versions 7.2 and later of Confluent Platform. For more details, view Java compatibility with Confluent Platform by version.
  • An install of the Confluent Hub Client. Note that this is installed by default with Confluent Enterprise.

Install the connector using the Confluent CLI

To install the latest connector version, navigate to your Confluent Platform installation directory and run the following command:

confluent connect plugin install confluentinc/kafka-connect-tibco-source:latest

You can install a specific version by replacing latest with a version number as shown in the following example:

confluent connect plugin install confluentinc/kafka-connect-tibco-source:1.0.0-preview

TIBCO client library

The Kafka Connect TIBCO connector does not come with the TIBCO JMS client library. If you are running a multi-node Connect cluster, the TIBCO connector and TIBCO JMS client JAR must be installed on every Connect worker in the cluster. For detailed instructions, see Installing TIBCO JMS client library.

Installing TIBCO JMS client library

This connector relies on a provided tibjms client JAR that is included in the TIBCO EMS installation. The connector will fail to create a connection to TIBCO EMS if you have not installed the JAR on each Connect worker node.

The installation steps are:

  1. Download and Install TIBCO Enterprise Message Service™ (Mac or Linux). If you have already installed TIBCO EMS, skip to the next step.

  2. Unzip the download and copy only the tibco/ems/{version}/lib/tibjms.jar file into the share/java/kafka-connect-tibco-sink directory of your Confluent Platform installation on each worker node.

    Note that The share/java/kafka-connect-tibco-sink directory is for Confluent Platform. If you are using a different installation, find the location of the Confluent TIBCO Sink connector JAR files and place the tibjms JAR file into the same directory.

  3. Restart all of the Connect worker nodes.

Install the connector manually

Download and extract the ZIP file for your connector and then follow the manual connector installation instructions.

Quick start

This quick start uses the TIBCO Sink connector to consume records from Kafka and send them to TIBCO Enterprise Message Service™ - Community Edition.

  1. Download TIBCO Enterprise Message Service™ - Community Edition (Mac or Linux) and run the appropriate installer. See the TIBCO Enterprise Message Service™ Installation Guide for more details. Similar documentation is available for each version of TIBCO EMS.

  2. Install the connector through the Confluent Hub Client.

    # run from your CP installation directory
    confluent connect plugin install confluentinc/kafka-connect-tibco-sink:latest
  3. Install the TIBCO JMS Client Library.

  4. Start Confluent Platform.

    confluent local start
  5. Produce test data to the sink-messages topic in Kafka.

    seq 10 | confluent local produce sink-messages
  6. Create a tibco-sink.json file with the following contents:

      "name": "TibcoSinkConnector",
      "config": {
        "connector.class": "io.confluent.connect.jms.TibcoSinkConnector",
        "tasks.max": "1",
        "topics": "sink-messages",
        "tibco.url": "tcp://localhost:7222",
        "tibco.username": "admin",
        "tibco.password": "",

        "confluent.topic.bootstrap.servers": "localhost:9092",
        "confluent.topic.replication.factor": "1"
  7. Load the TIBCO Sink connector.


    You must include a double dash (--) between the topic name and your flag. For more information, see this post.

    confluent local load tibco --config tibco-sink.json
  8. Confirm that the connector is in a RUNNING state.

    confluent local status tibco
  9. Confirm the messages were delivered to the connector-quickstart queue in TIBCO.
