Hi

I have some problem to connect PostgeSQL server from client mechine, error and code is given below. I am using Windows 7 OS

Code

public static void main(String[] args) {
       
        try {
            System.out.println("Connecting..................");
            Class.forName("org.postgresql.Driver").newInstance();
            connection = DriverManager.getConnection("jdbc:postgresql://10.10.10.101:6060/mydb", "postgres", "welcome");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Error

                    # comma-separated list of addresses;

pg_hba.conf

# TYPE  DATABASE        USER            ADDRESS                 METHOD
