Not able to connect to Query Service via a simple jdbc call

Steps to reproduce:

Run the following program with build 1854

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

/*

• This example shows
• a) How to run a simple SELECT statement using the Couchbase JDBC driver.
• b) How to retrieve scalar field values from the rows.
  */
  public class SimpleSelects {
  static String ConnectionURL = "jdbc:couchbase://172.23.123.107:8093";

public static void main(String[] args) throws Exception {
Connection con = DriverManager.getConnection(ConnectionURL);
Statement stmt = con.createStatement();

ResultSet rs = stmt
.executeQuery("select name, abv, (abv > 5) as strong from `beer-sample` where type = 'beer' limit 10");

/*ResultSet rs = stmt
.executeQuery("select count as MYCOUNT from `mobile` limit 10");*/
System.out.println("TEN BEERS");
while (rs.next())

{ //String name = rs.getString("name"); double abv = rs.getDouble("MYCOUNT"); //boolean strong = rs.getBoolean("strong"); //System.out.println("name: " + name + ", abv: " + abv + ", strong: " + strong); System.out.println("MYCOUNT: " + abv); }

System.out.println();

/* rs = stmt.executeQuery("select category, count as num from `beer-sample` where type = 'beer' group by category");
System.out.println("BEER CATEGORIES");
while (rs.next())

{ System.out.println(rs.getString("category") + ": " + rs.getInt("num")); }

*/
}
}

Here is the error I am getting
