I am struggling with some problem regarding Camunda Message Correlation.
I saw the video from BPMN Messaging on Youtube, but i am wondering if there is a way to setup 2 processes. Process A runs on the process engine on PC A, and Process B runs on the engine B on PC B. Process A uses a send task to send some message to a receive task on Process B which is located on another IP address but in the same network.
I managed to run a Process on PC A and send a command with postmen from PC B to start the process. That is no problem.
Command like this:
On side A: localhost:8080/engine-rest/process-definition/key/Process_1kaxj2c/start
On side B: 192.168.1.111:8080/engine-rest/process-definition/key/Process_1kaxj2c/start
Thanks for answering so fast. Yes i thought thats the way, but i did not managed to get it done. Can you give me a deeper insight pls? The best would be an example.
It’s pretty straight forward.
the endpoint is 192.168.1.111:8080/engine-rest and the call is linked in my post above.
If you have any particular problem problem or error occurring when you try it, let me know.
Ok thank you. I will try to find it out. But where do i configure the endpoints? I did not find any related method in the docs.
Can i add the endpoint IP to the specific message in the java class?
With postman it is pretty straight forward, yes. Simply use the link: ‘localhost:8080/engine-rest/message’ or ‘192.168.1.111:8080/engine-rest/message’. But that’s trivial. What i want to achieve is not to use postman. I want that the java class with the execution method handles the message sending on a different IP.
When i deploy process A which has a send task with a java class (delegation) attached which correlates a message named ‘overhanding2’ i get the error ‘Cannot correlate message ‘overhanding2’: No process definition or execution matches the parameters’. As expected because ‘overhanding2’ is defined in the receive task in process B running on engine B on another IP. But not on process A, engine A. How can i connect this?
Unfortunately I am facing a build failure causing from a plugin. Error msg: Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.17:test (default-test) on project customer: Tests in error:
** IntegrationTest.testHappyPath » IllegalState Failed to load ApplicationContext**
** InMemoryH2Test.com.camunda.consulting.customer.unit.InMemoryH2Test » NoClassDefFound**
Is there also a way without using spring framework?
Ok the project shows how you can send messages between pools. But my problem is that i have 2 separated processes and they communicate with send and receive tasks.
Do you think you can setup a project like this in the youtube video with AskTDog. And the asktDog process is located on another PC on another Engine? This would be fantastic.
