Connection con = null;
try {
String driver = "com.mysql.jdbc.Driver";
Class.forName(driver).newInstance( );
}
catch( Exception e ) {
System.out.println("Failed to load MySQL driver.");
return;
}
try {
con = DriverManager.getConnection("jdbc:mysql://localhost/mydatabase?user=myname&password=mypassword");

.....下略
