Question

Assuming I have a web app (Java EE 6), I want to realize the following use case:

1. On a generic “register” page, user enters his/her email and submits
2. System sends email to user. In this mail, there should be a link to a full registration page
3. User follows link, fills out required credentials, and submits
4. System stores user in database, and sends confirmation email
5. All temporary data is discarded.

The part I am having problems with is mostly step 2. What I need to know is the following:

1. What is the best way of setting up a personal registration page for the user? Should I generate a temporary page and link to it? Should I give the user a special cookie? In either case, how can I implement this? No code is needed, I just need some pointers on where to start looking and coding.

EDIT:

A very important question here, no matter how I do it, is the following: How can I generate and deploy a temporary webpage? I am rather new to Java EE, so forgive me if this has an obvious answer.

Answer 1

If the registration page is standard for every user then there is no need in creating a temporary page and linking to it or creating a special cookie etc… Just create the page with the registration form on it and send your clients a link to that.

If you want a special customized registration page for a specific user, then you can just send an e-mail with a link to your client with their information as a query parameter (ie http://yoursite.com/registration?fname=jordan&lname=denison) or you could use something like PrettyFaces to make the URL more readable as well as making it easier to extract those parameters and fire a method with them.
