I dont get it! How do I create an sql database on my own computer?

[Addez]

Hello!
I'v been searching all morning trying to figure out how to do it.
I tried downloading Microsoft SQL Server 2008 R2
But it can't find the server MSSQLSERVER as I belive I named it
while using the setup.

Anyways, Im woundering if there is any simple way to create an SQL database AND be able to use it?!

Following an example from the webb, totaly without documentation I got this far:

String driverName = "org.gjt.mm.mysql.Driver"; // MySQL MM JDBC driver 
			Class.forName(driverName); // Create a connection to the database 
			String serverName = "MSSQLSERVER"; 
			String mydatabase = "mydatabase"; 
			String url = "jdbc:mysql://" + serverName + "/" + mydatabase; // a JDBC url 
			String username = "username"; 
			String password = "password"; 
			connection = DriverManager.getConnection(url, username, password); 
			} catch (ClassNotFoundException e) { // Could not find the database driver 
				
			} catch (SQLException e) { // Could not connect to the database

But I meen WTBuuck Is driverName?!
How do I know the url?!
I dont use username NOR password FFS! I used microsoft authorication thingys!

Please help me, I can't keep working on my project, reading txt files for info.
It simply does not work -.-

If you have the Java 1.6 JDK installed on your computer you also have installed JavaDB (Derby); look in your C:\Program Files\Sun directory; everything is there. JavaDB is a full ANSI compliant relational database engine with ISO 92 SQL implemented. Your documentation (see that directory) tells you how to set up the stuff (it's easy).

kind regards,
