I want to change a value in cookie, I am using:

public static void main(String[] args) throws Exception {
    URL url;
    HttpURLConnection conn;

    url = new URL("http://google.pt");

    conn = (HttpURLConnection) url.openConnection();

    conn.addRequestProperty("Cookie", "COOKIE=QUALQUERCOISA");
    conn.setRequestProperty("Cookie", "COOKIE=QUALQUERCOISA");

    for (int i = 1; (conn.getHeaderFieldKey(i)) != null; i++) {
        System.out.println(conn.getHeaderField(i));
    }
}

The output is:

Pay for Cookies to response header and load cookieManager try:

static final String COOKIES_HEADER = "Set-Cookie";
HttpURLConnection connection = ... ;
static java.net.CookieManager msCookieManager = new java.net.CookieManager();

Map<String, List<String>> headerFields = connection.getHeaderFields();
List<String> cookiesHeader = headerFields.get(COOKIES_HEADER);

if(cookiesHeader != null)
{
    for (String cookie : cookiesHeader) 
    {
      msCookieManager.getCookieStore().add(null,HttpCookie.parse(cookie).get(0));
    }               
}

Then to get the cookie from the cookieManager and load it into the connection:

if(msCookieManager.getCookieStore().getCookies().size() > 0)
{
    //While joining the Cookies, use ',' or ';' as needed. Most of the server are using ';'
    connection.setRequestProperty("Cookie",
    TextUtils.join(";",  msCookieManager.getCookieStore().getCookies()));    
}

I solved the problem with:

        conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        conn.setDoOutput(true);
        conn.setRequestProperty("Cookie","JSESSIONID=" + string_com_jsessionid);
        conn.connect();
