Question

I am using Spring MVC with JSON as specified in Ajax Simplification Spring 3.0 article.

After so many attempts and variations of my code depending on advice found on various forums, my code still doesn’t work.

I keep on getting the following error: (406) The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request “accept” headers ().

I have in my appconfig.xml as required.

app-config.xml

    <context:component-scan base-package="org.ajaxjavadojo" />

    <!-- Configures Spring MVC -->
    <import resource="mvc-config.xml" />

mvc-config.xml

<mvc:annotation-driven />

<!-- Forwards requests to the "/" resource to the "index" view -->
<mvc:view-controller path="/" view-name="index"/>


<!-- Resolves view names to protected .jsp resources within the /WEB-INF/views directory -->
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="mediaTypes">
<map>
  <entry key="html" value="text/html"/>
  <entry key="json" value="application/json"/>
</map>
</property>
<property name="viewResolvers">
<list>
  <bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
  <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/views/"/>
    <property name="suffix" value=".jsp"/>
  </bean>
</list>
</property>

</bean>

This is what I have for my controller

@Controller
@RequestMapping (value = "/convert")
public class ConversionController {

  @RequestMapping(method=RequestMethod.GET)
  public String getConversionForm(){
    return "convertView";
  }

  @RequestMapping(value = "/working", headers="Accept=application/json", method=RequestMethod.GET)
  public @ResponseBody Conversion getConversion(){
    Conversion d = new Conversion("d");
    return d;
  }
}

jsp jquery call

  function convertToDecimal(){
    $.getJSON("convert/working", {key: "r"}, function(aConversion){
      alert("it worked.");
      $('#decimal').val(aConversion.input);
    });
  }

I would really appreciate any input on this issue.
Thank you

Answer 1

Try remove the header limitation for Accept, put a breakpoint and see what’s the actual value. Or do this with FireBug.

Also take a look at this jquery issue
