This article describes how to implement a JS7 workflow with two shell jobs that communicate over a Message Queue Service (MQ). These jobs include one job for publishing and one job for receiving and executing JS7 - REST Web Service API calls.

...

• the js7-jms-example.jar used in this example.,
• a configuration file named js7-jms-example.config containing credentials for the connection and information about the workflow.

...

• Either download the .jar file from the Active MQ web site and add it to the class path
• or, in the case of a Maven project; , add the following dependency to the project configuration.
  
  

...

# Message Server Settings
jms_url             = tcp://localhost:61616
jms_queue_name      = test
jms_time_to_live    = 5000 

# JS7 JOC Cockpit Settings
joc_api_url         = http://localhost:4444/joc/api/
username            = root
password            = root

# /orders/add API Settings
controller_id       = js7
workflow_path       = /myWorkflowToStart

...

• the produce argument specifies the use of a SOSProducer to publish a message (JSON body) to a Message Queue Service.
• the consume argument specifies the use of a SOSConsumer to read a message (JSON body) from a Message Queue Service andto:
  • login to the JS7 REST Web Service API,
  • send the API call /orders/add with the body received from the Message Queue Service and finally to
  • logout.

The Java executable has to be included in the PATH environment variable or the Java call has to be adjusted to include the path to the Java executable.
