[Registration Page] (25pt)

For this assignment, add a registration page to the online movie review application you developed in Homework 4 so a user can create an new account. In the registration page, ask the user to fill out a form as shown in the following example:

Your application should properly handle the following errors:

• Required fields are empty.
• Username is shorter than 4 characters.
• Username conflicts with an existing username.
  
• Password is shorter than 4 characters.
• Password and re-typed password do not match.

For each type of errors, output an error message and ask the user to re-enter the data. Note that validation of the input data should be implemented on the server side, i.e. not in JavaScript. Optional fields can be empty, which should not be treated as an error. However, if a user do provide the optional information, you must store it in the database.

Once a user is registered, they may add movies or reviews as described in previous assignments.

[Paged Display] (45pt)

Modify you movie index page so it only displays the five most recently added movies. For example:

When a user clicks on the More Movies link, the application shows all the movies in the database in a paged display. For example:

For this assignment, you must use Displaytag (http://displaytag.sourceforge.net/11/) to create the paged display. You should have at least eleven movies in your database, and display five movies per page.
