Help submitting HTML form via SpringMVC and RESTful Web Service

**socal_javaguy** · Oct 9th, 2009, 10:22 PM

Hello there,

I am created an online form using SpringMVC tag library (as a JSP file) and also a Controller (think Model View Controller pattern) as a RESTful Web Service.

When I deploy and invoke the web service by doing this in the browser:

http://localhost:8080/myapp/applications/new

Am able to view the SpringMVC based form (in Firefox) but when I enter in information and click on Submit, it displays the following:

Code:

HTTP Status 404 - /application/new

type Status report

message /application/new

description The requested resource (/application/new) is not available.

The RESTful Web Service (Controller):

Code:

@Controller
@Path(ApplicationResource.APPLICATION_URL)
public class ApplicationResource
{
	private final Logger log = LoggerFactory.getLogger(ApplicationResource.class);
	
	public static final String APPLICATION_URL = "/applications";

	@Autowired
	private ApplicationManager applicationManager;

	@POST
	@Path("create")
	@Produces(MediaType.TEXT_HTML)
	public ModelAndView getNewApplication(@Context HttpServletRequest request)
	{
		log.debug("Inside getNewApplication() method.");
		ModelAndView modelAndView = new ModelAndView("/applications/applications_new");
		String message = "";
		try 
		{
			if ("POST".equalsIgnoreCase(request.getMethod()))
			{
				String name = request.getParameter("name");
				String description = request.getParameter("description");
				String imgUrl = request.getParameter("imgUrl");
				Application app = new Application();
				if (app != null)
				{
					app.setName(name);
					app.setDescription(description);
					app.setImgUrl(imgUrl);
					applicationManager.save(app);
					message = "Added application: " + app.getName();
				}
				else
				{
					message = "Invalid";
				}
				modelAndView.addObject("message", message);
			}
		}
		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());
		}
		return modelAndView;
	}

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

applications_new.jsp (Here's the view (which does launch when I invoke it)):

Code:

<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>

<html>
<body>
<form:form commandName="application" method="POST" action="/application/new">
	<table>
	<tr>
	  <td>Name:</td>
	  <td><form:input path="name"/></td>
	</tr>
	<tr>
	  <td>Description:</td>
	  <td><form:input path="description" /></td>
	</tr>
	<tr>
	  <td>Image URL:</td>
	  <td><form:input path="imgUrl" /></td>
	</tr>
	</table>
	<input type="submit" value="submit" />
</form:form>
</body>
</html>

What could I be possibly be doing wrong?

Thank you for taking the time to read this...

It's issues like this that make me wish there was a BeanPostProcessor that would scan for all @Path annotations and print out the resulting URL segments. It would be a good review of what you've declared, and comparing that against what you're trying to call would be enlightening.

In this case, I believe you're declaring the root of your URL to be "/applications/...", but you're trying to call "/application/...".
