try
{
String userName = "root";
String password = "";
//<facility> is my database
String url = "jdbc:mysql://localhost/facility";
Class.forName ("com.mysql.jdbc.Driver").newInstance ();
conn = DriverManager.getConnection (url,userName,password);
System.out.println ("Database connection established");
}
catch (Exception e)
{
System.out.println ("Cannot connect to database server " +e.getClass().getName());
}
