I've just finnished reading the 'JavaEE 6 Tutorial Guide' and going through the Netbean IDE e-commerce tutorial to get to grips with the basics of JavaEE 6. Before I start building some sample applications I really wanted to try and find a tutorial/guide that explains how to go about creating a web application that has 'user accounts'. Ie. a user can create an account, They can then sign in to their account with their username and password and they are presented with their account (ie. the data and resources displayed are specific to them).
Any help would be really appreciated.
