Post XML to jersey rest webservice

Question

i'm trying to post a message from a facelet (.xhtml) page to a REST web service (Jersey). I think it would be possible to do within javascript/jQuery if the server would have, let's say

<?php header('Access-Control-Allow-Origin: *'); ?>

However the server seems to not have a property like that, and I don't know where to modify that in the config.

I tried this;

var settings = {
  "async": true,
  "crossDomain": true,
  "url": "example.com",
  "method": "POST",
  "headers": {
    "content-type": "application/xml",
    "cache-control": "no-cache"
  },
"data": 
  "<consultation>\n    \n\
    <consultationDescription>"+description+"</consultationDescription>\n    \n\
    <customerName>"+fullName+"</customerName>\n    \n\
    <customerPhone>"+phonenumber+"</customerPhone>\n    \n\
    <endDateAndTime>"+endDateAndTime+"</endDateAndTime>\n    \n\
    <startDateAndTime>"+startDateAndTime+"</startDateAndTime>\n\n\
  </consultation>",
  contentType: "application/xml", 

$.ajax(settings).done(function (response) {
  console.log(response);
});

But I only get cross origin error.

So should I try to find where to modify the origin on the server, or should I go with a different approach? Maybe a < h:form > and post via a javabean like #{sendXML.someMethod} etc, but I don't know where to find the syntax for that. I've been stuck with this problem for some time and can't find a good answer. Do you guys have any idee what to do?

Click green cell --> Write message (submit) --> book time on server. Update view.

So I figured out how to do it by following this guide: http://www.mkyong.com/java/how-to-send-http-request-getpost-in-java/

private final String USER_AGENT = "Mozilla/5.0";

// HTTP POST request
private void sendPost() throws Exception {
try  {
    String url = "http://myurl";
    URL obj = new URL(url);
    HttpURLConnection con = (HttpURLConnection) obj.openConnection();

    //add reuqest header
    con.setRequestMethod("POST");
    con.setRequestProperty("Accept-Language", "UTF-8");
    con.setRequestProperty("content-type", "application/xml");

    String urlParameters = "<myXML></myXML>";

    // Send post request
    con.setDoOutput(true);
    DataOutputStream wr = new DataOutputStream(con.getOutputStream());
    wr.writeBytes(urlParameters);
    wr.flush();
    wr.close();
catch (Exception e) {
    e.printStackTrace();
}
}

Since javascript did not work due to Cross Domain error, doing the work in a Javabean worked just fine.

I changed the code example by modifying Http s URLConnection to a HttpURLConnection and added con.setRequestProperty("content-type", "application/xml").

I also wrapped the statment with a try/catch.

I probably stated my question poorly from the beginning. But by doing the operations in the bean it worked for me.
