Getting error when submitting form using SpringMVC and REST

Hello there,

Created an online form in JSP using SpringMVC tag libraries. The controller for my form is a RESTful web service.

The RESTful web service has two calls:

(1) http://localhost:8080/myapp/applications/new

This brings up the online form in the browser (this works).

(2) http://localhost:8080/myapp/applications/create

This saves the form data to a database (handles submit). This is where it breaks.

Followed the conventions from the sample demo petclinic app which comes with the Spring Framework.

Online form:

The RESTful web service which serves as form controller:

@Controller
@Path(ApplicationsResource.APPLICATION_URL)
public class ApplicationsResource
{
	private final Logger log = LoggerFactory.getLogger(ApplicationsResource.class);

public static final String APPLICATION_URL = "/applications";

@Autowired
	private ApplicationManager applicationManager;

@POST
	@Path("create")
	@Produces(MediaType.TEXT_HTML)
	@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
	public void getNewApplication(@Context HttpServletRequest request, @ModelAttribute Application app)
	{
		log.info("ApplicationsResource - Inside getNewApplication() method.");
		String contentType = request.getContentType();
		log.info("Content-Type:" + contentType);
		
		try
		{
			if ("POST".equalsIgnoreCase(request.getMethod()))
			{
				if (app != null)
				{
					applicationManager.save(app);
					log.info("Added application: " + app.getName());
				}
				else
				{
					log.info("Application not added");
				}
			}
		}
		catch (Exception e)
		{
			log.info("Exception: ", e);
			throw new WebApplicationException(Response.status(RestError.SERVER_ERROR_HTTP_RESP).type("application/json;charset=utf-8").entity(new ErrorOutput(RestError.SERVER_ERROR_CODE, RestError.SERVER_ERROR_MSG, e.toString())).build());
		}
	}
	
	@InitBinder
	public void setAllowedFields(WebDataBinder dataBinder)
	{
		dataBinder.setDisallowedFields(new String[] {"id"});
	}

@GET
	@Path("new")
	@Produces( { MediaType.TEXT_HTML })
	public ModelAndView getNewApplicationForm()
	{
		log.info("ApplicationsResource - Inside getNewApplicationForm");
		ModelAndView mv = new ModelAndView("/applications/applications_new");
		mv.addObject("application", new Application());
		return mv;
	}
}

Exception thrown when I click on submit:

Does anyone know why I am getting this exception?

Would really appreciate it if someone could help me with this issue...

Happy programming and thank you for taking the time to read this.

Found the solution!

It was a RESTEasy problem... The fix was putting the @Form Application App inside the parameter list and prepending the domain model object's setters with @FormParam("name").
