Contexts and Dependency Injection (CDI)

Create a simple JSF application for managing documents (or integrate the following functionalities into an existing application). The application will allow the following:

• An authentication mechanism based on username and password.
• Register new users and assign them a specific role, for example admin, guest, etc.
• Specify a time frame, in which registration is open for users and submissions.
• The possibility to upload a document (for guests) and to view all uploaded documents (for admin). Each uploaded document will have a uniquely generated registration number. All submissions will be logged in a text file.

Use Contexts and Dependency Injection (CDI) for:

• the management of application's beans;
• decoupling the components using dependency injection (for example, producer methods);
• decoupling orthogonal concerns, such as logging;
• decoupling bussines concerns, such as verifying the date for operations like registration and submission;
• data validation, using Bean Validation annotations;
• implementing at least one event-based comunication (for instance, whenever a new document is uploaded a message is produced and all observers of this type of event will be notified).

Web Services

Create RESTful Web services using JAX-RS that allow the interaction with at least one JPA entity, implementing CRUD operations. For example, the application may offer the following:

• adding a new document and deleting an existing document from the database (RestService);
• Use XML or JSON for representing consumed or produced data.

Java EE Security

Add security features to the application created in the previous lab, using standard mechanisms offered by Java EE for:

• Authentication
• Controlling the access to Web resources
• Securing EJB components
