PUT request returning a 400 Bad Request Error

I am doing a PUT request to RESTfull service which changes password of a user. For the time being I have just hardcoded values of new and old password in my AJAX test my service. However it is giving me a 400 error.

AJAX call

$.ajax({
        type: "PUT",
        url: "api/teachers/"+user,
       data: {"old":"123","new":"qwe"},
       contentType: "application/json",
        success: function(data,status) 
        {
            datax = data;
            alert(data+status);
            ko.applyBindings(new AddMarkSheetKo(data));           
       },
        error: function(XMLHttpRequest, textStatus, errorThrown)
        {
            alert(XMLHttpRequest+textStatus+ errorThrown);
                  // error handler here
        }
      });

Restful function:

    @PUT
    @Path("/{name}")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response changePwd(@PathParam ("name")String name,@QueryParam ("old") String old, @QueryParam("new") String nw){
        System.out.println("entered function"+old+nw);
        Teacher t = DataAccessUtil.getByName(Teacher.class, name);
        if(t.getPassword().equals(old)){
            t.setPassword(nw);
            DataAccessUtil.update(t);
            return Response.ok().build();
        }
        else{
            return Response.status(Status.BAD_REQUEST).entity("Wrong password !!!").build();

        }
        //return reposnse;
    }

This information might be useful that on the console it prints

entered functionnullnull

So it the restfull function is called however it is not receiving the query parameters.

Any help would be really appreciated!

First, you could replace the @QueryParam annotations with @FormParam ones to retrieve the 'new' and 'old' parameters of the PUT request. Then, you should remove the @Consumes("application/json") annotation and contentType:application/json from your server and browser side code, and finally replace the submitted data in JSON format into something like 'new=qwe&old=123'.

If you want to stay with a content in JSON format, you should probably map the incoming body with an entity (ie, a Java class annotated with JAXB annotations), so that the JAX-RS implementation you use could unmarshall the incoming JSON content into a Java object.

HTH.
