Getting error when submitting form using SpringMVC and REST
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:
<%@ 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>

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:
interface org.springframework.ui.Model of content type: application/x-www-form-urlencoded at
org.jboss.resteasy.core.MessageBodyParameterInjector$1 createReaderNotFound(MessageBodyParameterInjector.java:73)
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.
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").
See: Integrating RESTEasy with SpringMVC
You haven't told your controller what mime types it accepts and how to map them, it needs a Reader associated with that mime type to map it and send it into your method.
