I am trying to call the process instance remotely, copy the code from Chapter 17. Remote API section

17.1.1.1. Example usage

When I ran the code, I got java.lang.NoSuchMethodError: org.apache.http.auth.AuthState.update(Lorg/apache/http/auth/AuthScheme;Lorg/apache/http/auth/Credentials;)V exception.

If I include all the runtime jar from jbpm-install then it works just fine.

Can somebody please help and advise if I miss out anything?

Dependency put in the pom file.

        String deploymentId = "com.sample:test:1.0";

        String user = "krisv";

        String password = "krisv";

        RemoteRuntimeEngineFactory restSessionFactory = new RemoteRestRuntimeFactory(

                deploymentId, instanceUrl, user, password);

        RemoteRuntimeEngine engine = restSessionFactory.newRuntimeEngine();

        KieSession ksession = engine.getKieSession();

        TaskService taskService = engine.getTaskService();

        Map<String, Object> params = new HashMap<String, Object>();

        params.put("customerId", "1234");

        ProcessInstance processInstance = ksession.startProcess("test.testRemoteCall", params);

        long procId = processInstance.getId();

        String taskUserId = user;

        taskService = engine.getTaskService();

        List<TaskSummary> tasks = taskService.getTasksAssignedAsPotentialOwner(user, "en-UK");

        long taskId = -1;

        for (TaskSummary task : tasks) {

            if (task.getProcessInstanceId() == procId) {

                taskId = task.getId();

            }

        }

        if (taskId == -1) {

            throw new IllegalStateException("Unable to find task for " + user

                    + " in process instance " + procId);

        }

        taskService.start(taskId, taskUserId);

    }

}

Got this exception.
