JavaFX2: Consume Restful services

I am trying to work on an architecture to consume RESTFul services from a JavaFX application. The requirement is to use spring's rest template(Not too pressed for this. If spring does not work then probably I can look at jersey or resteasy.

My setup is as below:

My main class has a dropdown listing values from a RESTFul service.

The architecture to hit the RESTFul services is as below:

  1. I have a client class that gives me the instance of the service class that hits the rest services.

  2. In the service class, I have various methods that I hit on the RESTFul service.

    public MyService1()
{
    AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(
        MyConfig.class);
    context.registerShutdownHook();
}

@Autowired
private RestOperations restTemplate;

private final Logger   LOG = LoggerFactory.getLogger(MyService1.class);

public List<MyObject> getMyObjects() throws IOException
{
    HttpEntity<MultiValueMap<String, HttpEntity<?>>> request = new HttpEntity<MultiValueMap<String, HttpEntity<?>>>(
        createParts(), createMultiPartHeaders());

    Map<String, String> vars = new HashMap<String, String>();

    List<MyObject> myObjects = restTemplate.getForObject(
        "http://localhost:8080/my-webservices/objects", List.class, vars);

    return myObjects;
}

With the above setup, I get the exception:

Exception in Application start method
Exception in thread "main" java.lang.RuntimeException: Exception in Application start method

It seems like you have not added the dependency library containing "BeanCreationException" class. Please add the jar file of spring as dependency for that JavaFX Project.
