mysql - java.net.ConnectException: Connection refused

Question

I am trying to connect to a mysql database on remote server and whenever I try to run the code it is giving me connection refused exception.

 Connection con = null;
          String driver = "com.mysql.jdbc.Driver";
          String url1="jdbc:mysql://IPADDRESS:3306/";
          String db = "hola";
          String dbUser = "root";
          String dbPasswd = "root";
          Class.forName(driver).newInstance();
          con = DriverManager.getConnection(url1+db, dbUser, dbPasswd);
          System.out.println("Database Connection Established");

Also, when I telnet with that IP on a port 3306 it is giving me connection refused. How can I make sure that my server listens to connection over port 3306?

Answer 1

java.net.ConnectException: Connection refused means that the IP address or port number you've entered is incorrect!
