CSNS Source Code

[Calendar for CSNS]

For this assignment, complete the following features of the CSNS calendar described in Homework 3:

(40pt) Display the calendar. The calendar should provide the same functions as described in Homework 2, i.e. displaying current month, highlighting current date, and allowing a user to select previous/next month or a date. Note that if you use an existing library for the calendar, make sure that the library allows you to highlight any date (i.e. not just current date), because in future assignments you will be asked to highlight dates that have events associated with them.
(20pt) Add new tasks.
(20pt) Display tasks. Note that tasks must be listed in the order in which they are added.
(20pt) Mark tasks as completed. Note that completed tasks are removed from the display, but they are still stored in the database.

[Notes]

Add Calendar to the Resources top menu of CSNS. Clicking on Calendar should take a user to the default calendar display.

The user interface design is up to you. Good user interface design will receive up to 30pt extra credit after the whole calendar project is completed. Note that a good UI design is not necessarily fancy or colorful, but it has to be functional, intuitive, convenient, and pleasant.

For this assignment, you may want to allow only registered users to access the calendar. To do so, you may modify the filterInvocationInterceptor bean definition in /conf/spring-security.xml to protect the URL of the calendar. For example, suppose the calendar can be accessed at the URL /calendar.html, you may add the following line to the filterInvocationInterceptor bean definition:

/calendar.html=ROLE_USER

Note that the URL must consist of only lower-case letters. We will discuss security in more details later.

[About Submission and Grading]

Before submitting your work, commit all the changes to your Subversion repository and create a tag.

If you use any libraries that are not in the original CSNS and are not included in your csns.zip, please upload the library jar files together with csns.zip when you submit your work.

To test your project, we will use the following SQL scripts in your csns.zip to create, populate, and then clear the database:

db/csns-create.sql
db/csns-test-insert.sql
db/csns-drop.sql

Please make sure that these scripts are up to date and can be run in their entirety without generating any errors.
