Cannot find Symbol error on Web Services Tutorial

[stepcicc]

Good day

I've added a JAVA ME Webservice client to my project. I have managed to retrieved the WSDL file and created the stub file successfully. My problem lies in the waitScreen source code. Basically I have login screen that send username and password to web service that returns boolean. I have a "Cannot find symbol" error on bold code. I'm new at Java so not sure how to handle this error. Should I add the webservice as reference somewhere even though the project appears under Source Packages?

My code for waitScreen is as follows:

task1 = new SimpleCancellableTask();
task1.setExecutable(new org.netbeans.microedition.util.Executable() {
public void execute() throws Exception {
// write task-execution user code here
AuthenticateService auth = new AuthenticateService_Stub();
boolean logged = auth.Authenticate(getLoginScreen().getUsername(),getLoginScreen().getPassword());
if (!logged) throw new Exception();

Thank you
