Login/Registration system in JSP

Emerson

I'm currently trying to setup a website with a login system.
The site is being done completely in JSP.
I'm using MYSql as the database.

I want users to be able register their details and then login with their chosen username and password to access information from the database specific to their account.

I'm using Apache Tomcat as our server.
There's a tutorial here for creating a similar system under Geronimo & Derby SQL, but I'm not sure if it's merely a case of altering this to work with MySql:

I changed:

driver = (Driver) ([B]com.ibm.db2.jcc.DB2Driver.class[/B]).newInstance();
            } catch(Exception e) {
                throw new IllegalArgumentException("Unable to load, instantiate, or register driver "+
                                                   driver+": "+e.getMessage());
            }
            
            try {
                Properties prop = new Properties();
                prop.put("user", "system");
                prop.put("password", "manager");
                Connection conn = driver.connect("jdbc:derby:net://localhost:1527/SystemDatabase;", prop);

to:

driver = (Driver) ([B]com.mysql.jdbc.Driver[/B]).newInstance();
            } catch(Exception e) {
                throw new IllegalArgumentException("Unable to load, instantiate, or register driver "+
                                                   driver+": "+e.getMessage());
            }
            
            try {
                Properties prop = new Properties();
                prop.put("user", "actualdbusername");
                prop.put("password", "actualdbpassword");
                Connection conn = driver.connect("jdbc:mysql://localhost/jspod;", prop);

Am I barking up the wrong tree?
Thanks
