Hello there,
Created an online form in JSP using SpringMVC tag libraries. The controller for my form is
a RESTful web service (JBoss RESTEasy).
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:
| <%@ 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 modelAttribute="application" method="POST"
action="create">
| <table>
| <tr>
| <td>Name:</td>
| <td><form:input path="name" size="30"
maxlength="80"/></td>
| </tr>
| <tr>
| <td>Description:</td>
| <td><form:input path="description" size="30"
maxlength="80"/></td>
| </tr>
| <tr>
| <td>Image URL:</td>
| <td><form:input path="imgUrl" size="30"
maxlength="80"/></td>
| </tr>
| </table>
| <input type="submit" value="Save" />
| </form:form>
| </body>
| </html>
|
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:
| Failed executing POST /applications/create
|
| org.jboss.resteasy.spi.BadRequestException:
|
| Could not find message body reader for type:

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.
