Application JEE

Work to do. Using JSP, JSTL (especially core and SQL tags), and a relational database (e.g. MySQL), develop a simple application with the following functionality:

The application stores in the database a set of (key, value) pairs for each user.
A user can:
retrieve some or all of the (key, value) pairs using some filter on the key,
modify the set of (key, value) pairs: add a new pair, update or remove an existing pair.
Users must log into the application before accessing their data; the password is stored in the database.
The application must conform with the MVC Model 2 architecture.

Suggested development process:

First develop the application UI with JSP and JSTL core tags. At this stage, the (key, value) pairs are stored as HTTP session attributes.
Next, interface the application with the database using JSTL SQL tags.
Note: in a real-world application, JSPs do not access the application's database directly. Instead, they interact with EJBs, which access the database.
