MySQL java connection - kan ikke oprette forbindelse
Er igang med at forbinde java til en MySQL database for første gang og støtte ind i lidt problemer. Har installeret xampp som jeg ofte bruger sammen med php, hvilket virker helt fint. Har også importeret de nødvendige klasser. Har følgende kode:import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class Main {
public static void main(String[] args) throws Exception
{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/testdb","root","root");
PreparedStatement statement = con.prepareStatement("select * from name");
ResultSet result = statement.executeQuery();
while(result.next()) {
System.out.println(result.getString(1) + " " + result.getString(2));
}
}
}
Får følgende fejl i konsollen:
Exception in thread "main" java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

Jeg bruger eclipse forresten, hvis det skulle have nogen betydning.
