The request sent by the client was syntactically incorrect?

I have a controller like follows 

@Controller
public class SettingsController {
   @RequestMapping(value="/editname",method=RequestMethod.POST)
   public void editName(@RequestParam(value="firstname") String firstname,
                        @RequestParam(value="lastname") String lastname) {
      final Object principal = 
         SecurityContextHolder.getContext().getAuthentication().getPrincipal();
      try {
         jdbcPersonRepository.updateName(principal.toString(), firstname, lastname);
      } catch (SignInNotFoundException e) {
      }
    }
 }

and I have my ajax form submit.

 $(function() {
  //twitter bootstrap script
    $("button#submit").click(function(){
    var $form = $(this).closest("form");
    var type = $form.attr('method');
    $.ajax({
      type: $form.attr('method'),
      url: $form.attr('action'),
      data: $form.serialize(),
      dataType : "json",
        success: function(msg){
                $("#thanks").html(msg)
               $("#form-content").modal('hide');    
        },
        error: function(){
           //alert("failure");
        }
      });
});
});

and my twitter bootstrap model which has a form which triggers the ajax is as follows

  <!-- Name Edit div -->
<div id="form-content" class="modal hide fade in" tabindex="-1">
  <form name="edit-form" action="<c:url value="/editname" />" method="post">
    <div class="modal-header">
      <h4>Edit Name</h4>
    </div>
    <div class="modal-body">
     <div class="control-group">
        <div class="controls">
          <ul class="nav nav-list">
            <li class="nav-header">First Name</li>
            <li><input type="text" placeholder="First Name" name="firstName" id="firstName" class="input-xlarge help-inline"></li>
            <li class="nav-header">Last Name</li>
            <li><input type="text" placeholder="Last Name" name="lastName" id="lastName" class="input-xlarge help-inline"></li>
         </ul>
        </div>
      </div>
    </div>
    <div class="modal-footer">
       <button id="submit"  class="btn btn-success">Update</button>
       <button class="btn" data-dismiss="modal" >Close</button>
    </div>
  </form>
</div>

Does any anybody have a clue regarding this error. ?

In the method declaration, the @RequestMapping annotations give the parameter names as firstname and lastname. In the form HTML they are firstName and lastName.

Request parameter names are case sensitive ... ergo, they don't match, and Spring tells you this is an invalid request because mandatory parameters are missing.
