I am unable to connect to mysql cluster database after starting my management node, data node, mysql node. I made the necessary changes by adding the loadbalance in the dbURL. But I am not able to access the connection. The mysqld port is 1186. Please assist.

String dbURL = "jdbc:mysql:loadbalance://localhost/bank";
String dbDriver = "com.mysql.jdbc.Driver";
private Connection dbCon;
public boolean connect() throws ClassNotFoundException, SQLException {
        Class.forName(dbDriver);

        // login credentials to your MySQL server
        dbCon = DriverManager.getConnection(dbURL, "root", ""); 
        return true;
    }

The error I am getting when I try to log in is:

javax.servlet.ServletException: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

How do I test MySQL cluster database? I managed to login using the following in command prompt. Please assist.

mysql -h 127.0.0.1 -P5000 -u root
