How to send java object in angular JS

I have JS file that is trying to do a POST method, but needs a specific java object as input.

here is the signature of the Post method in the server:

@Path("/branches")
public class BranchResource {

@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response post(BranchDescriptor branch) {
.
.

here is the the JS function (using Angular)

$scope.retry = function() {
    $http({
           url : "rest/branches",
           method : "POST",
           dataType : "json",//not sure is needed
           data : "way to get Branch descriptor "
           headers : {
                 "Content-Type" : "application/json; charset=utf-8",
                 "Accept" : "application/json"
           }
    }).success(function(data) {
           $scope.items = data;
    }).error(function(data) {
           alert('err');
    });
 };

I was receiving the following errors:

??? 27, 2014 3:27:48 PM com.sun.jersey.spi.container.ContainerRequest getEntity
SEVERE: A message body reader for Java class    xxx.api.BranchDescriptor, and Java type class xxx.BranchDescriptor, and MIME media type application/octet-stream was not found.
The registered message body readers compatible with the MIME media type are:
application/octet-stream ->
  com.sun.jersey.core.impl.provider.entity.ByteArrayProvider
  com.sun.jersey.core.impl.provider.entity.FileProvider
  com.sun.jersey.core.impl.provider.entity.InputStreamProvider
  com.sun.jersey.core.impl.provider.entity.DataSourceProvider
  com.sun.jersey.core.impl.provider.entity.RenderedImageProvider
*/* ->

So, I tried to add a data like that:

data : { "_protectedBranch" : "pf_something", "_newBranch" : "some_branch", "_commitId" : "some_commit", "_commiter" : "someone" },

and got the following error:

??? 27, 2014 3:42:46 PM com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException
SEVERE: The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container
org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "_protectedBranch" (Class xxx.BranchDescriptor), not marked as ignorable
 at [Source: HttpInputOverHTTP@66aee27d; line: 1, column: 22] (through reference chain: xxx.BranchDescriptor["_protectedBranch"])
    at org.codehaus.jackson.map.exc.UnrecognizedPropertyException.from(UnrecognizedPropertyException.java:53)

How can I Pass the BranchDescriptor object for sending? What am I missing?

OK, found out what I was missing, it was just a way of creating the branch and send it to the data in the http:

var branch = {
            protectedBranch:"some_branch",
            newBranch:"some_branch",
            commitId: "some_commit",
            commiter:"some_commiter"
    }
    $scope.retry = function() {
        $http({
               url : "rest/branches",
               method : "POST",
               data : branch,
               headers : {
                     "Content-Type" : "application/json; charset=utf-8",
                     "Accept" : "application/json"
               }
        }).success(function(data) {
               $scope.items = data;
        }).error(function(data) {
               alert('err');
        });

hope it will be help to others.

You don't need the dataType and you can try sending an object instead of string like that:

$http({
   url : "rest/branches",
   method : "POST",
   data : {branch : "way to get Branch descriptor" },
   headers : {
        "Content-Type" : "application/json; charset=utf-8",
        "Accept" : "application/json"
   }
})

In the docs:

The $http service will automatically add certain HTTP headers to all requests.

  • Accept: application/json, text/plain, * / *
  • Content-Type: application/json

Angular js sends the request with the above headers unlike jQuery which sends this:

  • 'application/x-www-form-urlencoded; charset=UTF-8'

You need to pass a javascript object in data like this : data: {param1: param1value, param2: param2value}
