Problems with building custom worklist application

Question

I'am trying to build a custom worklist application using this: http://download.oracle.com/docs/cd/E15523_01/integration.1111/e10224/bp_worklistcust.htm
Here is the code I've built so far (it si quite simple but, for now, I'm just trying to get hold of the concepts involved):
public class Test {
public static void main(String[] args) {
IWorkflowServiceClient wfsc = WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.REMOTE_CLIENT);
ITaskQueryService queryService = wfsc.getTaskQueryService();
IWorkflowContext context;
try {
context = queryService.authenticate("jstein", "welcome1".toCharArray(), null);
} catch (WorkflowException e) {
e.printStackTrace();
When I run this I get the following exception trace:
Exception in thread "main" oracle.bpel.services.workflow.client.WorkflowServiceClientException: javax.naming.NameNotFoundException: Unable to resolve 'TaskQueryService'. Resolved '' [Root exception is javax.naming.NameNotFoundException: Unable to resolve 'TaskQueryService'. Resolved '']; remaining name 'TaskQueryService'

I would appreciate any help. I'm really stuck with this..
Thanks! :)

Answer 1

I've finally found a solution to this problem. The problem was that I was trying to connect to a workflow api on the *7001* port but that wasn't the correct port. The correct port is *8001*.
I came to this conclusion quite accidental (or out of desperation if you like).
What I don't understand is that in every single official Oracle document about workflow and worklist the port they were targeting was *7001*. I have to emphasize that I installed SOA 11g suite with all default settings.
Problem solved, moving on.
