How to connect to a remote MySQL database with Java?

I am trying to create a JSF application using the Eclipse IDE. I am using a remote mySQL server as my database. How do I connect to this remote database for creating tables and accessing them?

Just supply the IP / hostname of the remote machine in your database connection string, instead of localhost. For example:

jdbc:mysql://192.168.15.25:3306/yourdatabase

Make sure there is no firewall blocking the access to port 3306

Also, make sure the user you are connecting with is allowed to connect from this particular hostname. For development environments it is safe to do this by 'username'@'%'. Check the user creation manual and the GRANT manual.

You need to pass IP/hostname of the rempote machine in the connection string.

import java.sql.*;
import javax.sql.*;

public class Connect
{
   public static void main (String[] args)
   {
       Connection conn = null;

       try
       {

           String url = "jdbc:mysql://localhost:3306/mydb";
           Class.forName ("com.mysql.jdbc.Driver");
           conn = DriverManager.getConnection (url,"root"," ");
           System.out.println ("Database connection established");
       }
       catch (Exception e)
       {
           e.printStackTrace();

       }
       finally
       {
           if (conn != null)
           {
               try
               {
                   conn.close ();
                   System.out.println ("Database connection terminated");
               }
               catch (Exception e) { /* ignore close errors */ }
           }
       }
   }
}

to access database from remote machine , you need to give grant all privileges to you data base.

run the following script to give permissions: GRANT ALL PRIVILEGES ON . TO user@'%' IDENTIFIED BY 'password';

Plus, you should make sure the MySQL server's config (/etc/mysql/my.cnf, /etc/default/mysql on Debian) doesn't have "skip-networking" activated and is not binded exclusively to the loopback interface (127.0.0.1) but also to the interface/IP address you want connect to.
