Add Custom HTTP Header to Request sent by BlazeDS and AMF

in our application we have a flex Client, this client uses BlazeDS and AMF to excute operation,
Is there a way to add a custom Http header to the request sent from the AMF so i can read in our Filter in Java server Side
Thanks.

You can use a custom header with anything you like in it, like this:
headers = [
new URLRequestHeader("contentType", "application/x-www-form-urlencoded"),
new URLRequestHeader("Accept-Language", "en_US"),
new URLRequestHeader("X-Authorization", "Bearer " + API_KEY)
];
Then use it like:
var urlReq:URLRequest = new URLRequest(API_URL);
urlReq.method = URLRequestMethod.GET;
urlReq.requestHeaders = headers;
var _jsonLoader:URLLoader = new URLLoader();
_jsonLoader.load(urlReq);

Dropwizard Jersey client Multipart http request

Dropwizard (Version 0.8.2) uses Jersey internally to provide HTTP client. I am using this client to send a Multipart POST request to an external Rest Endpoint to a SMS Service. Code is given below but it doesn't seems to be working because i am not receiving any message through this method also it does not throw any error.
URI for the first sample is http://enterprise.com/GatewayAPI/rest?userid=%s&password=%s&method=xlsUpload&filetype=zip&msg_type=TEXT&auth_scheme=PLAIN&v=1.1
FileDataBodyPart fileDataBodyPart = new FileDataBodyPart(fileName, file,
MediaType.APPLICATION_OCTET_STREAM_TYPE);
FormDataMultiPart multiPart = new FormDataMultiPart();
multiPart.field("fileName", fileName).bodyPart(fileDataBodyPart);
Entity<FormDataMultiPart> entity =
Entity.entity(multiPart, multiPart.getMediaType());// MediaType.MULTIPART_FORM_DATA_TYPE)
Client tenacityClient = TenacityJerseyClientBuilder
.builder(AppDependencyKeys.BULK_SMS)
.usingTimeoutPadding(Duration.milliseconds(500)).build(client)
.register(MultiPartFeature.class);
Invocation invocation = getResourceBuilder(tenacityClient, uri).buildPost(entity);
Future<Response> futureResponse = invocation.submit();
long start = System.currentTimeMillis();
futureResponse.get();
But the same works with below method when i use Apache Commons Httpclient. working code for the same is given below.
HttpClient client = new HttpClient();
PostMethod method = new
PostMethod("http://enterprise.com/GatewayAPI/rest");
Part[] parts = {
new StringPart("method", "xlsUpload"),
new StringPart("userid", "*******"),
new StringPart("password", "*******"),
new StringPart("filetype", "zip"),
new StringPart("v", "1.1"),
new StringPart("auth_scheme", "PLAIN"),
new FilePart(file.getName(), file)
};
method.setRequestEntity(new MultipartRequestEntity(parts, method.getParams()));
int statusCode = client.executeMethod(method);
log.info("Status code: {}", statusCode);
But i want to use the first way as that suits my infrastructure better.

I think you should set up properly media type for entity. Currently, you created new FormDataMultiPart but, you did not set and media type and it uses "text/plain" y default.
So, you should set up MediaType.APPLICATION_OCTET_STREAM_TYPE to your FormDataMultiPart as media type.

PHP RESTful API accessing Jersey Client POST data

I am using a PHP RESTful API which is consumed by a Java desktop application using jersey 2.21.
Usually, when I send a POST request from AngularJS, I can access the data via:
$data = json_decode(file_get_contents("php://input"));
However, when I use jersey, the data is put in the $_POST array. Here is my Jersey code:
final HashMap<String, String> params = // some hashmap with a few entries
ClientConfig config = new ClientConfig();
Client client = ClientBuilder.newClient(config);
MultivaluedMap formData = new MultivaluedHashMap(params);
WebTarget target = client.target(url);
// Get JSON
String jsonResponse = target.request(MediaType.APPLICATION_JSON_TYPE).post(Entity.entity(formData, MediaType.APPLICATION_FORM_URLENCODED_TYPE), String.class);
return jsonResponse;
How do I post the data from Jersey so that I can access it via the above PHP call?
I know I can just use the $_POST array, but I need this API to be consumed from a mobile app, Java desktop & an AngularJS app.
Thanks in advance

Thanks to #jonstirling, I got it.
I had to set the content type as JSON. here is the updated code:
ClientConfig config = new ClientConfig();
Client client = ClientBuilder.newClient(config);
WebTarget target = client.target(url);
String data = new Gson().toJson(params);
// POST JSON
Entity json = Entity.entity(data, MediaType.APPLICATION_JSON_TYPE);
Invocation.Builder builder = target.request(MediaType.APPLICATION_JSON_TYPE);
String jsonResponse = builder.post(json, String.class);
return jsonResponse;

EodData wsdl java connection

I am stuck trying to figure out how to initiate a WSDL connection with EodData.com
the wsdl address is
http://ws.eoddata.com/data.asmx?wsdl
I am using CXF to create a client connection:
QName qname = new QName("http://ws.eoddata.com/Data", "Data");
Data data = new Data(new URL("http://ws.eoddata.com/data.asmx?wsdl"), qname);
DataHttpGet dataGet = data.getDataHttpGet();
dataGet.login("xxx", "ppp");
and I got
Caused by: org.apache.cxf.interceptor.Fault: Unmarshalling Error: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Header"). Expected elements are <{http://ws.eoddata.com/Data}LoginResult>
Not sure how I should initiate the connection?

A quick test using the following code worked for me.
Using WSDL2Java:
wsdl2java -autoNameResolution http://ws.eoddata.com/data.asmx?wsdl
Then using the code you provided with a few changes:
QName qname = new QName("http://ws.eoddata.com/Data", "Data");
Data data = new Data(new URL("http://ws.eoddata.com/data.asmx?wsdl"), qname);
DataSoap dataSoap = data.getDataSoap();
LOGINRESPONSE response = dataSoap.login("xxx", "ppp");
System.out.println(response.getMessage());
The response was:
Invalid Username or Password

Using the Jersey client to do a POST operation

In a Java method, I'd like to use a Jersey client object to do a POST operation on a RESTful web service (also written using Jersey) but am not sure how to use the client to send the values that will be used as FormParam's on the server. I'm able to send query params just fine.

Not done this yet myself, but a quick bit of Google-Fu reveals a tech tip on blogs.oracle.com with examples of exactly what you ask for.
Example taken from the blog post:
MultivaluedMap formData = new MultivaluedMapImpl();
formData.add("name1", "val1");
formData.add("name2", "val2");
ClientResponse response = webResource
.type(MediaType.APPLICATION_FORM_URLENCODED_TYPE)
.post(ClientResponse.class, formData);
That any help?

Starting from Jersey 2.x, the MultivaluedMapImpl class is replaced by MultivaluedHashMap. You can use it to add form data and send it to the server:
WebTarget webTarget = client.target("http://www.example.com/some/resource");
MultivaluedMap<String, String> formData = new MultivaluedHashMap<String, String>();
formData.add("key1", "value1");
formData.add("key2", "value2");
Response response = webTarget.request().post(Entity.form(formData));
Note that the form entity is sent in the format of "application/x-www-form-urlencoded".

It is now the first example in the Jersey Client documentation
Example 5.1. POST request with form parameters
Client client = ClientBuilder.newClient();
WebTarget target = client.target("http://localhost:9998").path("resource");
Form form = new Form();
form.param("x", "foo");
form.param("y", "bar");
MyJAXBBean bean =
target.request(MediaType.APPLICATION_JSON_TYPE)
.post(Entity.entity(form,MediaType.APPLICATION_FORM_URLENCODED_TYPE),
MyJAXBBean.class);

If you need to do a file upload, you'll need to use MediaType.MULTIPART_FORM_DATA_TYPE.
Looks like MultivaluedMap cannot be used with that so here's a solution with FormDataMultiPart.
InputStream stream = getClass().getClassLoader().getResourceAsStream(fileNameToUpload);
FormDataMultiPart part = new FormDataMultiPart();
part.field("String_key", "String_value");
part.field("fileToUpload", stream, MediaType.TEXT_PLAIN_TYPE);
String response = WebResource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(String.class, part);

Simplest:
Form form = new Form();
form.add("id", "1");
form.add("name", "supercobra");
ClientResponse response = webResource
.type(MediaType.APPLICATION_FORM_URLENCODED_TYPE)
.post(ClientResponse.class, form);

Also you can try this:
MultivaluedMap formData = new MultivaluedMapImpl();
formData.add("name1", "val1");
formData.add("name2", "val2");
webResource.path("yourJerseysPathPost").queryParams(formData).post();
