Hi
I was trying out the example on Camunda External Task Client (https://github.com/camunda/camunda-external-task-client-java/tree/master/examples/loan-granting).
I tried the above tutorial step by step. After deploying, I can see the process stuck at the first task.
But apparently the class App is not executing, coz I am not able to see the variables set during the first external task and the execution is not moving to next step.
Am I missing something here?. Why isn’t the external task executing and moving after the first step.
I am attaching my bpmn.
testExternal2.bpmn (3.8 KB)
public class App {
public static void main(String... args) throws InterruptedException {
// bootstrap the client
ExternalTaskClient client = ExternalTaskClient.create().baseUrl("http://localhost:8080/engine-rest").build();
// subscribe to the topic
client.subscribe("emailListener").lockDuration(1000).handler((externalTask, externalTaskService) -> {
// retrieve a variable from the Workflow Engine
int key1 = externalTask.getVariable("key1");
List<Integer> creditScores = new ArrayList<>(Arrays.asList(key1, 9, 1, 4, 10));
// create an object typed variable
ObjectValue creditScoresObject = Variables.objectValue(creditScores).create();
// set the recently created variable
externalTask.setVariableTyped("creditScores", creditScoresObject);
// complete the external task
externalTaskService.complete(externalTask);
// ,
// Collections.singletonMap("creditScores", creditScoresObject)
System.out.println("The External Task " + externalTask.getId() + " has been completed!");
}).open();
// subscribe to the topic
client.subscribe("caseCreation").lockDuration(1000).handler((externalTask, externalTaskService) -> {
// retrieve a variable from the Workflow Engine
ObjectValue creditScoresObject = externalTask.getVariable("creditScores");
externalTaskService.complete(externalTask);
System.out.println("The External Task " + externalTask.getId() + " has been completed!");
}).open();
Thread.sleep(3000);
}
}
