Java Connection Problem
Hello,
I've made a program that connects to a Mysql database, but when i connect to my local host (a mysql database on a apache server) it works just fine.
I've also got an account at www.downfire.com and there's my online mysql database which I also use for a website.
When i try to connect to this database i get the following error:
Exception in thread "main" com.mysql.jdbc.CommunicationsException: Communication
s link failure due to underlying exception:
** BEGIN NESTED EXCEPTION **
java.net.SocketException

The code i use is :
import java.sql.*;
import java.awt.*;
import java.awt.event.*;
public class TestDB {
public static void main(String[] args) throws Exception {
System.out.print("Geef FilmNaam in :");
String result = Invoer.leesString();
System.out.println("Registreren Driver....");
Class.forName("com.mysql.jdbc.Driver");
System.out.println("OK");
System.out.println("Maken Connectie....");
//local settings
/*String mysqlUser = "localuser";
String mysqlPass = "";
String mysqlHost = "localhost/dbname";*/
//online settings
String mysqlUser = "user";
String mysqlPass = "password";
String mysqlHost = "192.168.0.11/dbname";
Connection conn = DriverManager.getConnection("jdbc:mysql://"+mysqlHost, mysqlUser, mysqlPass);
System.out.println("OK");
System.out.println("Statement aanmaken.....");
Statement statement=conn.createStatement();
System.out.println("OK");
System.out.println("Uitvoeren Query\n\n\n\n\n");
ResultSet rs = statement.executeQuery("select naam from naam where naam like " +"'%"+result+"%'");
System.out.println("***********************************************************");
while (rs.next()){
System.out.println(rs.getString(1));
}
System.out.println("***********************************************************");
System.out.println("\n\n\n\n\nConnectie afsluiten");
conn.close();
System.out.println("OK.");
}
}
