Spring POST not returning valid numbers

Question

I am extremely new to spring, but I managed to come up with this code from my javascript

$scope.addMe = function(){
        var params = {
            date :111111,
            username: 'thisGuy',
            notetext: 'this is a new note that was just added'
        };
        $http.post(afHttp.baseUrl + "/blah/" + $scope.dog.id, {params: params})
            .success(function(data) {
            });
    }

and in elclipe I have

@POST
@Path("/{id}")
public void getAddMssg(@PathParam("id") int id, @FormParam("date") int date, @FormParam("username") String username, @FormParam("notetext") String notetext) {
    System.out.println("date:      "+date);
    System.out.println("username:   "+ username);
    System.out.println("notetext:   "+ notetext);
    System.out.println("id:   "+ id);

}

And when I look at my console log in eclipse it says

date:   0
username:   null
notetext:   null
id:   123124

What am I doing wrong? I have been working on this for awhile with no avail. Can someone please help?

Oh sorry I forgot to add I am using angularjs.

Pass params into that argument, not {params:params}. Also, add the Content-Type header as the third argument:

$http.post(afHttp.baseUrl + "/blah/" + $scope.dog.id, params, {
    headers: { 'Content-Type': 'application/x-www-form-urlencoded'}})

And on the server-side, proceed @POST with @Consumes(MediaType.APPLICATION_FORM_URLENCODED):

@POST
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)

The fully qualified name for MediaType is javax.ws.rs.core.MediaType, in case you need to import it.

yes, I say that, see my comment, and user say that result is zero – baltov Oct 26 '13 at 16:23
I certainly am not an expert, but I want to figure this out. See if my latest update works please. – sdanzig Oct 26 '13 at 16:29
Okay, thanks, so I added that and got the error "(Unsupported Media Type)" when adding that – alex wilhelm Oct 26 '13 at 16:33

I am using angularjs, sorry about that. – alex wilhelm Oct 26 '13 at 15:53
ok, that is a error: replace {params:params} with params only: [link](http://docs.angularjs.org/api/ng.$http#methods_post) post(url, data, config) – baltov Oct 26 '13 at 16:02
I don't quite undestand, can you give an example of what you mean? – alex wilhelm Oct 26 '13 at 16:06
Oh sorry I was looking at the wrong thing, what would config be though? – alex wilhelm Oct 26 '13 at 16:08
$http.post(afHttp.baseUrl + "/blah/" + $scope.dog.id, params) .success(function(data) { }); In AngularjS post methot take second parameter data object, you send other object with name param. I think so is all right. Third parameter is optional. Not needed for you. – baltov Oct 26 '13 at 16:08
Yeah, I am still getting 0's and nulls – alex wilhelm Oct 26 '13 at 16:13
ok, add " HttpServletRequest request" as last parameter in java method and debug what is in. In _parameters variable. Sorry now i can't create a project to test that. – baltov Oct 26 '13 at 16:19
Can you elaberate on what you mean/ example? I have been googling HttpServletRequest request and I have not come up with anything that uses it as a java param. – alex wilhelm Oct 26 '13 at 16:30
[link](http://stackoverflow.com/questions/8504258/spring-3-mvc-accessing-httprequest-from-controller) I mean that: public void getAddMssg(@PathParam("id") int id, @FormParam("date") int date, @FormParam("username") String username, @FormParam("notetext") String notetext, HttpServletRequest request) {... Show us, please, new code for javascript function? – baltov Oct 26 '13 at 16:33
Am I suppose to use it in the body too? – alex wilhelm Oct 26 '13 at 16:35
debug it, set a breakpoint in first line in body, and see what is in – baltov Oct 26 '13 at 16:36
I have never really used debug before, but here are the errors I got for running it and putting a breaker on the first line: SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container com.sun.jersey.api.container.ContainerException: Exception obtaining parameters and Caused by: java.lang.IllegalStateException: The @FormParam is utilized when the content type of the request entity is not application/x-www-form-urlencoded – alex wilhelm Oct 26 '13 at 16:55
