JMS Messaging Support for Ignition Projects * * * ## Configure Messaging Broker 1. Install ActiveMQ on a server and configure it. ([INSTALLATION and CONFIGURATION 1. Install latest Java x64 JRE 2. Down - Pastebin.com](https://pastebin.com/cwW59zPR)) 2. Get an MQTT client. ([http://mqttfx.jensd.de/](http://mqttfx.jensd.de/)) 3. Establish a connection with your broker. ## Ignition Project 1. (PRE-REQ) Install Nick's Database Module. ([Database Module](http://www.perfectabstractions.com/database-module.html)) 2. Import attached project. ## Gateway Startup Turn up logging for 'activemq' logger. A couple things happen on the first strartup of the project: - **The latest activemq-all.jar is downloaded from Maven to %IGNITION\_INSTALL%/lib/core/gateway/activemq-all-latest.jar.** The JAR is manually added to JAVA paths upon download. Once Ignition services are restarted, the JAR is automatically loaded along with everything else in /lib/core/gateway. ([https://mvnrepository.com/artifact/org.apache.activemq/activemq-all](https://mvnrepository.com/artifact/org.apache.activemq/activemq-all)) - **Tables are created in 'DefaultH2' data source.** You will get an error in the gateway logs if this datasource is not found. ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/b/b8b7ed5df1da89f087eedbd28a16380302c77c56.png) _TABLES_ **activemq\_connections:** Your ActiveMQ connection strings and connection wide configuration. **activemq\_subscriptiontopics:** ActiveMQ topics that you will be subscribing to. Each topic can have a custom `MessageListener`. Leaving the column NULL will default to the generic listener (eg. `project.activemq.AMQMessageListenerScript.AMQMessageListener`). Custom message listeners can be added to shared.activemq.message\_listeners package (eg. `shared.activemq.message_listeners.CustomMessageListenerScript.CustomMessageListener`). ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/4/40f5e3f624c079215e4864150f930deff6915e06.png) **activemq\_connectionsubscriptionlinks:** Here is where you tell each connection what topics it should subscribe to. Joins connection Id to topic Id. **activemq\_projectsubscriptionlinks:** Here is where you allow a message received on a specific topic to be passed through to a project client message handler. Joins topic id to an Ignition project name. The project must have an `OnActiveMqMessage` client message handler. Your custom `MessageListener` overrides this functionality. During Gateway startup script execution, each connection is established and all enabled topics are subscribed to. Reconnections and resubscriptions are handled automatically. ## Publishing Messages from Ignition `shared.activemq.publisher.publishToConnectionId(connectionId,topicPath,message={})` `shared.activemq.publisher.publishToConnectionName(connectionName,topicPath,message={})` > TODO: automatic update facility for activemq-all.jar. > TODO: allow custom javax.jms.ExceptionListener > TODO: allow custom org.apache.activemq.transport.TransportListener > TODO: USE\_CASE\_SPECIFIC create memory tags from KV pairs and update value on message received > TODO: USE\_CASE\_SPECIFIC create com.inductiveautomation.ignition.common.sqltags.model.event.TagChangeListener and publish to ActiveMQ on memory tag value change > TODO: build client interface for managing connections > TODO: advisory/control layer between client and gateway [ActiveMQIntegration-global-latest.proj](https://us1.discourse-cdn.com/inductiveautomation/original/2X/b/b22eeae57f7d88e3c911d45ddfbf9d6a2fba4f71.proj) (4.0 KB) [ActiveMQIntegration-project-latest.proj](https://us1.discourse-cdn.com/inductiveautomation/original/2X/d/d0aa74b2a87ca5401bb8acfe905880a6e0225819.proj) (30.3 KB) ---

Hi Chris. Any word on the street whether OPC Foundation and the Object Management Group will merge their standards, thereby implementing a data or field messaging bus (OpenFMB) within OPC-UA? OMG’s DDS is used in military, and other situational awareness applications. It emphasizes a stateful way of being for all components on the data bus.

I have not heard, but would that be necessary since both specifications are building support for AMQP, MQTT, etc? ---

I was looking at DDS as a WAN closed loop control protocol. Looks like a wrapper of translator to make an OPC-UA server capable of being a node on DDS. ---

thanks for sharing, just tried your example, but the connection between Ignition and broker can’t be established. this error occured: “javax.jms.JMSException: Cannot send, channel has already failed: tcp://127.0.0.1:1883” ---

Hey. You have to talk to the native JMS port 61616. ActiveMQ routes the messages to other connected clients, regardless of the protocol. ---

are the project files complete, or the correct version? There seem to be windows missing, at least comparing what’s on the videos with what’s in the project files? I know the thread is quite old, but this looks like a great example to learn from. The maven link for the activemq jar seems to have gone away, but after downloading activemq-all-5.15.12.jar by hand to …/lib/core/gateway/activemq-all-latest.jar it does start up, create the H2 schema objects, but that’s as far as I get … attempting to create/save a connection definition results in the UI doing nothing. (checked the project file itself: only the main window is present in the definition. Shoud there be others for the subscription/topic and connection management as shown in the videos?
