How to start communication among these processes?

I have a workflow as below

sample.bpmn (3.4 KB)

So can we do interactions between send task , message start event and recieve task i.e. I want to send a message using send task which starts the start event and start event pass on the message or execute the receive task in the execution

It might be useful for you to follow this tutorial, it explains how messages work.

Hi Niall,
Thanks for the reply I watched referred video and it pretty much solve my doubts. But as explained in the tutorial when I’m trying to start a process using rest (http://localhost:8080/engine-rest/message),
I’m getting this error
{
“timestamp”: “2019-01-09T07:23:44.272+0000”,
“status”: 404,
“error”: “Not Found”,
“message”: “No message available”,
“path”: “/engine-rest/message”
}

Below is my pom file
pom.xml (2.3 KB)

Hi Niall,

Camunda rest end points are not working please tell me how to enable it.

Seems like your Camunda server isn’t running.
The REST API is available by default if you downloaded the standard distro.

I have started my application using @EnableProcess application using spring boot application. Below is my pom file have a look if something is miising
pom.xml (2.5 KB)

The Rest endpoint is different in the spring boot distro
try
localhost:8080/rest/message

You can read more about it in the docs: https://docs.camunda.org/manual/7.9/user-guide/spring-boot-integration/rest-api/
