JSON RPC Java dzhuvinov - how to set username and password?

I am using the Java library for JSON-RPC 2.0 from dzhuvinov. I am having problems setting my username and password for basic access authenticaition for the calls. My code looks like:

public static void main(String[] args)
{
    URL serverURL = null;
    try {
        serverURL = new URL("http://user:[email protected]:18332/");

    } catch (MalformedURLException e) {
        System.err.println(e.getMessage());
        return;
    }
     JSONRPC2Session mySession = new JSONRPC2Session(serverURL);
     String method = "getinfo";
     int requestID = 0;
     JSONRPC2Request request = new JSONRPC2Request(method, requestID);
     JSONRPC2Response response = null;
     try {
             response = mySession.send(request);

     } catch (JSONRPC2SessionException e) {
             System.err.println(e.getMessage());
             return;
     }
     if (response.indicatesSuccess())
        System.out.println(response.getResult());
    else
        System.out.println(response.getError().getMessage());
}

And I get a response of:

Network exception: Server returned HTTP response code: 401 for URL: http://user:[email protected]:18332/

Trying a similar code in Python I get a proper result:

access = jsonrpc.ServiceProxy("http://user:[email protected]:18332/")
print access.getinfo()

How can I configure the basic access authentication for my JSON RPC calls?

Not sure how library from 'dzhuvinov' deals with streams. But you can apply this code to perform basic authentication on HTTP-transport level opened by URL class.

URL url = new URL("http://user:[email protected]:18332/");
URLConnection conn = url.openConnection();
String userpass = rpcuser + ":" + rpcpassword;
String basicAuth = "Basic " + new String(new Base64().encode(userpass.getBytes()));
conn.setRequestProperty ("Authorization", basicAuth);
conn.setRequestProperty ("Content-Type", "application/json");
conn.setDoOutput(true);

Full code can be found here http://engnick.blogspot.ru/2013/03/java-trac-rpc-and-json.html . I used this to perform JSON-RPC stuff to communicate with API of Trac.

final String rpcuser ="...";
final String rpcpassword ="...";

Authenticator.setDefault(new Authenticator() {
  protected PasswordAuthentication getPasswordAuthentication() {
      return new PasswordAuthentication (rpcuser, rpcpassword.toCharArray());
  }});
