I connect with WB with this code:

 CommandWebService client = RemoteRuntimeEngineFactory.newCommandWebServiceClientBuilder() 
.addServerUrl(commandWsdlUrl) 
.addUserName(userId) 
.addPassword(passId) 
.addDeploymentId(deploymentId) 
.buildBasicAuthClient(); 

and I tray to use the GetProcessInstancesCommand:

    GetProcessInstancesCommand getProcessInstancesCommand = new GetProcessInstancesCommand ();
JaxbCommandsRequest request = new JaxbCommandsRequest(deploymentId, getProcessInstancesCommand);
JaxbCommandsResponse response = client.execute(request);

and it returns a empty list in processInstancesList variable but I have instances running in the project.+

I don't know what is the problem, can you help me, please?
