Final Project

Marco Ronchetti marco.ronchetti@unitn.it — Sun, 3 Jan 2021 22:49:00 +0100

Exam > Final Project

Develop a web application with the following requirements:

- Front end developed in Angular
- Back end devoloped in EJB, with a Web Server layer
- Database developed using Java DB (Derby), so that it can be delivered together with the ear.

The Web App must:
- have authentication-authorization (log in)
- have certain operations which are permitted to certain users (e.g. admins) but not to others
- use (meaniningfully) both stateless and stateful beans
- use AJAX (XHR)
- have at least a page where data change continously (as if pushed by the server)
- use Angular routing
- use CSS

You can chose the domain you like (e.g. an on-line store, an on-line bank, a news system with premium features for registered users...)

Source code, ear and populated database have to be delivered.

A report must be delivered, containing:
- overall description
- technical documentation (description of the main features)
- screenshots documenting the working app
-instruction on how to install and execute it.

The project must be delivered at least three days before the exam date.

5th Delivery

Assignments > 5th Delivery

Given the list of members of the Scottish Parliament, available at (https://data.parliament.scot/api/members)
create an angular application that lists the parliament members (showing their name, and if the PhotoUrl field is not empty add an icon to show that the photo is available).

Every name is linked to a personDetail page that:

shows the birthdate (if available)
shows the picture (if available)
shows the party to which the parliamentary belongs (using https://data.parliament.scot/api/memberparties and https://data.parliament.scot/api/parties. Suggestion: create a service to cache (part of) the data.
shows her/his website (if available, from https://data.parliament.scot/api/websites )

Use routing to allow moving between the two pages (the lists, and the personDetail).

Deploy the application serving it from the Tomcat embedded in Netbeans (i.e. create a simple Web project having your name in Netbeans that delivers the transpiled angular app, even as a static page).

Write a report using the following structure:

Title Page containing date, title , your name
Introduction (problem statement, description of the domain)
- 2.1 Implementation (report and comment the most relevant pieces of source code and config files)
- 2.2 Deployment (screen shots of your app running, documenting the various steps)
- 2.3 Comments and notes (any problems encountered during the project development, any other comment)

Create a zip having your name, containing:

the Tomcat project
the report
the Angular sources

Upload it onto piazza, in the folder “delivery_5” as a private message to the instructor.

Deadline: 23:59, January 17 if you plan to take the exam on Jan 21, else February 13 (last deadline, also for taking the exam in the summer).

Assignments > 4th delivery

Follow the tutorial:

http://www.mastertheboss.com/jboss-server/jboss-as-7/jboss-as-7-remote-ejb-client-tutorial

make it work. Embed the code in a Netbeans project named with your surname 4a. Deploy the application you developed into Wildfly.

Once done that, modify the code so that:
- instead of creating an account, you access it on a database (as in the past, use a derby DB stored in the project directory). Take care of transactions.
- instead of having a desktop java application client, you access it from a web client (use a Business Delegate in your code!).

The modified code should be in a Netbeans project named with your surname 4b.

If you have problems you can not solve, ask on Piazza! (and as usual, if you can help your peers on Piazza, please do it!)

HINT: if you google for solving problems, make sure that what you find is about EJB 3.x and not older stuff! Otherwise it gets confusing.

Write a report using the following structure:

Title Page containing date, title , your name
Introduction (problem statement, description of the domain)
Section 1: deploying the tutorial
- 1.1 screen shots of your app running, documenting the various steps
- 1.2 Comments and notes (optional: any problems encountered during the project development, any other comment)
Section 2: modification of the tutorial
- 2.1 Implementation (report and comment the most relevant pieces of soure code and config files)
- 2.2 Deployment (screen shots of your app running, documenting the various steps)
- 2.3 Comments and notes (any problems encountered during the project development, any other comment)

Create a zip having your name, containing the two projects and the report
Upload it onto piazza, in the folder “delivery_4” as a private message to the instructor.

Deadline: 23:59, Sunday Dec 6.

Reference material:

There is an old, but still valid free book available as pdf: Mastering EJB 3.0 . In the course we covered the following 9 chapters::

Overview
Pre-EJB 3.0: the world that was
The new EJB
Introduction to session beans
NOT COVERED (Writing Session Bean Web Services)

3rd DELIVERY

Marco Ronchetti marco.ronchetti@unitn.it — Sun, 18 Oct 2020 19:19:00 +0200

Assignments > 3rd DELIVERY

Create a Netbeans project named with your surname 3 (eg., for me it would be Ronchetti3) and containing a webapp with the same name.

On-line newspapers often offer a broadcasting of live events, such as soccer matches. We can outine the architecture of such an app in the following way:

a page, accessible only to the journalist, allows to add one-liners such as
"Leo Messi is going to be substituded by another player, because he's not feeling good after the fault on him."
Readers who connect to the newspaper page that broadcasts the match will get that line.

Typically, the readers' browser will every few seconds (say 15) ask the server if there is anything new, passing a token which identifies the last seen line.
The server will respond to the requesting browser passing all the lines, which have a token greater that the one sent by client, or the info that there is nothing new.
The browser will update the page with the info (the page is in the style of Single Page Application, and will update only what is needed, without performing a reload but only adding the new lines in a suitable place..

The initial token passed by a browser that is starting the connection will be 0.

You should implement a solution without using a database, and describe your choices in a report that explains what your app does. Zip the project and the pdf in a file having the same name as the project.

Upload it onto piazza, in the folder “delivery_3” as a private message to the instructor.

Deadline: 23:59, Sunday Nov 1.
