Mendapatkan sesi dari HttpAdapter ke Adaptor berbasis Java

Apakah ada cara untuk memasukkan sesi yang dibuat di httpAdapter ke kelas Java di adaptor? Saya terhubung ke https://jazz.net/ dengan httpadapter, tetapi sekarang saya ingin menggunakan beberapa kode Java untuk terhubung ke url yang sama di adaptor. Jadi saya tidak tahu cara mengakses sesi yang sudah dibuat.

Ini kode koneksi saya:

In javaScript, 
function login(){
var lpath = getLoginPath();
var input = {
    method : 'post',
    returnedContentType : 'html',
    path : lpath,
    parameters : {
        j_password : passwd,
        j_username : username
    }

};

var request = WL.Server.getClientRequest();
UserSession = request.getHeader("Cookie"); // here i am setting the value for a global variable UserSession.
return WL.Server.invokeHttp(input);
}

function getConnection(){
var instance = new com.worklight.customcode.PostRequest();

var rspath = getRootServicesPath();

var input = {
    method : 'get',
    returnedContentType : 'xml',
    path : rspath
};
return {
    result : instance.getXml(UserSession) // Here i am passing the value of session cookie into the java class 
};}

Di Kelas Java,

class PostRequest{
 public String getXml(String cookieString){
    String params = "?offlineData={'projectAreaItemId':'_iTuLUmxfEeKR3t32SVbLKQ','executables':[{'terItemId':'_TNoyQW6qEeKR3t32SVbLKQ','scriptItemId':'_DF89AW6qEeKR3t32SVbLKQ'}]}";
    String url = "https://jazz.net/sandbox02-qm/secure/service/com.ibm.rqm.execution.common.service.IOfflineExecutionRestService"
            + params;
URLConnection connection = new URL(url).openConnection();
connection = new URL(url).openConnection();
    connection.setRequestProperty("User-Agent", "yes");
    connection.setRequestProperty("Content-Type",
            "application/x-www-form-urlencoded");
    connection.setRequestProperty("Accept-Encoding", "gzip");
    connection.setRequestProperty("Accept", "application/xml");
    connection.setRequestProperty("Cookie", cookieString);
    connection.setDoInput(true);
    connection.setDoOutput(true);
    ((HttpURLConnection) connection).setRequestMethod("POST");
    connection.setDoOutput(true);
String result = "";
        InputStream resp = connection.getInputStream();
        StringBuilder s = inputStreamToString(resp);
return s;
}
}
