Question

I’m trying to call a Webservice that consumes a json object with post method .I did it then It wont work again don’t know what is the problem.
here is my method

@POST
@Path("/post")
@Consumes("application/json")
@Produces("application/json")
public Response testClient(Client c) throws IOException {
    System.out.println(c.getAdresseCl());
    ResponseBuilder builder = Response.ok(c.getAdresseCl());
    builder.header("Access-Control-Allow-Origin", "*");
    builder.header("Access-Control-Max-Age", "3600");
    builder.header("Access-Control-Allow-Methods", "*");
    builder.header(
            "Access-Control-Allow-Headers",
            "X-Requested-With,Host,User-Agent,Accept,Accept-Language,Accept-Encoding,Accept-Charset,Keep-Alive,Connection,Referer,Origin");
    return builder.build();
}

to call this I used this

$.ajax({
  type: 'POST',
  url: "http://localhost:9080/FournisseurWeb/jaxrs/clients/post",
  data: '{"adresseCl":"tunis"}',
  dataType:'json',
  contentType: "application/json; charset=utf-8", 
  success: function (msg) {
    alert(msg);
  },

  error: function (xhr, ajaxOptions, thrownError) {
    alert('error');
  }

});

well I remark that when I set the contentType to application/json the method changes to OPTIONS .
and when I don’t use the content type I got “415 Unsupported Media Type ” I dont know how to fix this. I passed too much time without results 🙁
thank you for helping me

this is the method that consumes a text xml fomat and map it to an object to persist it next

@POST
@Path("/inscription")
@Produces(MediaType.TEXT_HTML)
public Response testClient(String s) {
    ResponseBuilder builder = null;

    try {

        final String xmlString = s;
        final StringReader xmlReader = new StringReader(xmlString);
        final StreamSource xmlSource = new StreamSource(xmlReader);
        final JAXBContext jaxbContext = JAXBContext
                .newInstance(Client.class);
        final Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
        final Client client = (Client) unmarshaller.unmarshal(xmlSource,
                Client.class).getValue();
        System.out.println("nomCl  : " + client.getNomCl());
        System.out.println("prenomCl  : " + client.getPrenomCl());
        System.out.println("emailCl  : " + client.getEmailCl());
        System.out.println("numTel  : " + client.getNumTel());
        System.out.println("long_  : " + client.getLong_());
        System.out.println("lat  : " + client.getLat());
        System.out.println("LoginCl  : " + client.getLoginCl());
        System.out.println("PasswordCl  : " + client.getPasswordCl());
        System.out.println("adresseCl  : " + client.getAdresseCl());
        EntityManagerFactory factory;
        factory = Persistence.createEntityManagerFactory("FournisseurWeb");
        EntityManager em = factory.createEntityManager();
        em.getTransaction().begin();
        em.persist(client);
        em.getTransaction().commit();
        em.close();
        factory.close();
        builder = Response.ok("true");
    } catch (Exception e) {
        System.out.println(e.getMessage());
        e.printStackTrace();
        builder = Response.ok("false");
        builder.header("Access-Control-Allow-Origin", "*");
        builder.header("Access-Control-Max-Age", "3600");
        builder.header("Access-Control-Allow-Methods", "POST");
        builder.header(
                "Access-Control-Allow-Headers",
                "X-Requested-With,Host,User-Agent,Accept,Accept-Language,Accept-Encoding,Accept-Charset,Keep-Alive,Connection,Referer,Origin");
        return builder.build();
    }
    builder.header("Access-Control-Allow-Origin", "*");
    builder.header("Access-Control-Max-Age", "3600");
    builder.header("Access-Control-Allow-Methods", "POST");
    builder.header(
            "Access-Control-Allow-Headers",
            "X-Requested-With,Host,User-Agent,Accept,Accept-Language,Accept-Encoding,Accept-Charset,Keep-Alive,Connection,Referer,Origin");
    return builder.build();
}

I use to call this method using ajax with this sample :

var x="<client><nomCl>Taarit</nomCl><prenomCl>Aymen</prenomCl><emailCl>[e-mail]</emailCl><numTel>222</numTel><long_>1.66</long_></client>";
$.ajax({
        url: 'http://localhost:9080/FournisseurWeb/jaxrs/clients/cl',
        type: 'post',
        scriptCharset: "utf-8" ,
        dataType:"xml",
        data: x,
        success: function(data, status) {  
        console.log(data);         
        }
    });

this is a jax-rs call with ajax POST using cross domain so hope that it helps 🙂

NOTE: The cross-domain call without JSONP is legal here because the server is returning the following header, which enables cross-domain AJAX!

 builder.header("Access-Control-Allow-Origin", "*");

See Mozilla Developer Center page on Access-Control-Allow-Origin for more details.
