Camel-Camunda integration


#1

Hello people,

I am exploring the potential of “camel <-> camunda” integration. Specifically, I am interested in consuming external tasks from Camunda (The rest of camunda-bpmn component is out of scope for now)

Do I understand it correclty, that camunda-bpmn component has a dependency to Camunda engine ?


#2

Pls correct me if I am wrong: I think, that the error handling of “org.camunda.bpm.camel.component.externaltasks.TaskProcessor” is the reason for having an embedded camunda-engine?

private ExternalTaskService getExternalTaskService() {

    return camundaEndpoint.getProcessEngine().getExternalTaskService();

}

plus

 CamundaUtils.retryIfOptimisticLockingException(new Callable<Void>() {
            @Override
            public Void call() {
                externalTaskService.handleFailure(task.getId(),
                        task.getWorkerId(),
                        exception != null ? exception.getMessage() : "task failed",
                        retries,
                        calculatedTimeout);
                return null;
            }
        });

The loose coupling of Camunda BPMN and any client via external task client is imho not well implemented.

I will have a look at the other community project “https://github.com/camunda/camunda-external-task-client-spring-boot”. Though, I loose the Camel integration :frowning:
