I am an old guy…

From 1997 to 2007 I have been giving courses on Object Oriented Design (mostly Java and UML) and Real Time Systems (mostly SPARK and Ravenscar) at the European Space Agency

I am a Java software developer certified by Jive Software (http://www.jivesoftware.com/) and Oracle Middleware (http://www.oracle.com/technetwork/middleware/fusion-middleware/overview/index.html -http://www.spazioit.com/pages_en/sol_inf_en/oracle_adf_en/)

I am “currently” (2012-2015) setting up Software Quality Platforms for AIRBUS Helicopters (http://www.airbushelicopters.com) and ESA (http://www.esa.int).

I have been and still am working on some open source projects (e.g. ]project-open[ - http://www.project-open.org/en/list_partners)

Principles

We are not Microsoft (nor Oracle, whatever…).We do not have the strength, the capability, the know-how, the experience required to build, set-up and configure a proper (web) application development environment (unless of course we want to put an enormous amount of energy into it).

It is better to use a consolidate, corporate level, web application development framework.

Principles

We are not Microsoft (nor Oracle, whatever…).We do not have the strength, the capability, the know-how, the experience required to follow in a productive way the continuous evolution of Web technologies (e.g. what should we use for comms? XML? Json? MessagePack?).

It is better to let the developer of the selected web application framework to take care of the evolution of such technologies.

August 2015


9

Principles

User Interface

– Monotony and uniformity are good (e.g. all the pages must have the same structure, all the functions must share the same type of user interaction, and so on…).

– Minimalism is good.

– No deviation whatsoever from what is provided by the selected framework.

– Possibly an eye should be kept to both the desktop and the mobile targets.

August 2015


10

Principles

In selecting the appropriate web development framework, corporate level solutions should be preferred over solutions developed by small communities, single developers, etc…

E.g.

– Oracle ADF –http://www.oracle.com/technetwork/developer-tools/adf/overview/index.html

– OpenACS – http://www.openacs.org

11

Principles

The selected framework preferably should support both Windows and GNU/Linux.

Selecting a web development framework is not «having a date»; quite the opposite, it is «getting married».

Example Application

August 2015

Data First


31

Example Application

Class Tasks

– Create a new Fusion Web Application (Oracle ADF).

– Connect to the Database.

– Create the Model and the Data Control.

– Create two JSF pages (“animal” and “pet”) with the related tables inside.

– Deploy the application to Glassfish.

– Have the two pages showing in a browser.

August 2015


32

Example Application

Homework (0)

– Redo once again on your systems what has been done during the training session.

August 2015


33

Example Application

Homework (1)

– Add the Insert/Delete/Commit buttons to the two pages

– Create a Login and a Home Page. The login page is the first and only page the users can have access to; upon successful login (user name and password can be embedded in the code) the users are directed to the home page. In the home page there’s a menu allowing the user to go either to the Animal page or to the Pet page.

– Remove the id* key fields from the pages and create the required «TABLE»_IMPL methods for both tables .

– Change the Animal_idAnimal in the Pet view/page with a list of values.

– Add a field (version - varchar(45)) to both tables.
