Using a Portal Service

Question

Hi,
Am trying to use a portal service in my application and calling a method,it should return me the IResourceList which am going
to iterate and publish the Resource.
Interestingly,am getting the error "Build of the project Failed" Pls Note am working on JDI or NWDI & no compilation errors
at my end.
Please find the Code below :
user =(IUser) UMFactory.getUserFactory().getUserByLogonID(request.getUser().getLogonUid());
        IPortalRuntimeResources runtimeResources =PortalRuntime.getRuntimeResources();
IService aService = runtimeResources.getService("customer.MyService");
  customer.MyService tmp = (customer.MyService) aService;
  IResourceList list=(IResourceList)Util.getMethod(filterbasepath,arraylist,user);
Any help in this direction would be highly appreciated,kindly be specific as where have i gone wrong.
Regards
Manoj

Hi Harish,
1.Other components in the par file do not have classes with syntax error.
2.deployement descriptor has correct syntax.
3.deployement descriptor has services reference to the    Portal Service am using.
if i comment some part of the code say
user =(IUser) UMFactory.getUserFactory().getUserByLogonID(request.getUser().getLogonUid());
IPortalRuntimeResources runtimeResources =PortalRuntime.getRuntimeResources();
//IService aService = runtimeResources.getService("customer.MyService");
//customer.MyService tmp = (customer.MyService) aService;
//IResourceList list=(IResourceList)Util.getMethod(filterbasepath,arraylist,user);
i can upload the par file,that clearly indicates that
theres some problem in using the service "customer.MyService",though there are no compilation errors.
I have even tried the alternative
IService aService = runtimeResources.getService("IMyService.KEY");--->where IMyservice is the Interface Class.
