Hey guys,

Facing some issues when trying to use the remote Java API to start a process (the sample evaluation one) that is deployed on my workbench and I'm all out of ideas:

1) Here is my code that is connecting to the Workbench:
import static org.junit.Assert.*;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
 
 
import org.jbpm.test.JbpmJUnitBaseTestCase;
import org.junit.Test;
import org.kie.api.KieServices;
import org.kie.api.logger.KieRuntimeLogger;
import org.kie.api.runtime.KieSession;
import org.kie.api.runtime.manager.RuntimeEngine;
import org.kie.api.runtime.manager.RuntimeManager;
import org.kie.api.runtime.process.ProcessInstance;
import org.kie.api.task.TaskService;
import org.kie.api.task.model.TaskSummary;
import org.kie.services.client.api.RemoteRestRuntimeFactory;
import org.kie.services.client.api.command.RemoteRuntimeEngine;
public class ProcessRemoteTest {
 @Test
  public void test() throws MalformedURLException {
  String deploymentId = "org.jbpm:Evaluation:1.0";
        URL appUrl = new URL("http://localhost:8080/jbpm-console/");
        String user = "krisv";
        String password = "krisv";        
 
 
 
  RemoteRestRuntimeFactory  restSessionFactory  = new RemoteRestRuntimeFactory(deploymentId, appUrl, user, password);
        RemoteRuntimeEngine engine = restSessionFactory.newRuntimeEngine();
 
 
        KieSession ksession = engine.getKieSession();
     
        // start a new process instance
        Map params = new HashMap();
        params.put("employee", "krisv");
        params.put("reason", "Performance Evaluation");
        ProcessInstance processInstance =
             ksession.startProcess("evaluation", params);
        System.out.println("Process started ...");
   
  }
}



 2) Here is my pom.xml:

3. When running I see the following error trace:



4. I had a look at the server logs and this is what I saw as well:

I had a look online but really struggling to get any answers. Any ideas of what I could be doing wrong? I am completely blank atm.

Thanks!

Are you running community or redhat edition of JBPM?

I had all sorts of problems with redhat jbpm 6.1, I could not get the REST services to work. In the end I deployed the community edition of 6.2 and it works fine. One note, I used this line instead to get the runtime engine

RuntimeEngine engine = RemoteRuntimeEngineFactory.newRestBuilder().addUrl(new URL(instanceUrl)).addUserName(user).addPassword(password).addDeploymentId(deploymentId).build();
