JDBC MYSQL Connection without specifying database?

I am using the SphinxQL MySQL client which stores indexes as "tables" but has no real notion of a "database"...One specifies the port (9306 in my case) at which the sphinx mysql instance listens and in theory should be able to communicate as normal.

I have the following test code:

     import java.sql.*;

        public class Dbtest{


                public static void main (String[]args){


                        try{

                   Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:9306",
 "user","password");
    con.setReadOnly(true);
       Statement stmt = con.createStatement();

     ResultSet res = stmt.executeQuery("SELECT * from index_turned_table");

       while (res.next()){
        String stuff1 = res.getString(1);
        String stuff2 = res.getString(2);
        System.out.println("Adding " + stuff1);
        System.out.println("Adding " + stuff2);

                    }


            res.close();
            stmt.close();
           con.close();
                        }
             catch(Exception e)
                 {
             System.out.println (e);
                  }

                }
        }

Upon execution, the code just hangs and does nothing and doesn't print out an exception. What are useful things I can do to figure this out or if any one has direct experience what might be going on?
