The cookies set in header Set-Cookie . To get it you can use the following code:

URLConnection urlConnection = new URL("url-of-your-web-app-here").openConnection();
List<String> cookiesList = urlConnection.getHeaderFields().get("Set-Cookie");

You can delete flag manually, by deleting HttpOnly :

response.setHeader( "Set-Cookie", "name=value; HttpOnly");

If you're working in a Servlet 3.0 or newer environment, configure your web.xml as following:

<session-config>
   <cookie-config>
      <http-only>false</http-only>
   </cookie-config>
</session-config>

Note. The HttpOnly flag is an additional flag that is used to prevent an XSS (Cross-Site Scripting) exploit from gaining access to the session cookie.
