Online Calendar Using Hibernate

Project application requirement is to build Online Calendar using servlet, JSP, Hibernate. Please find the doc below for further instructions. This is very fast pace project. Needs further up-gradation on other modules as well.

==================================================================================

[Reading]

• Hibernate Book (Java Persistence with Hibernate)

o Chapter 1-6 (or corresponding chapters in Hibernate in Action). You may skip anything related to XDoclet, Annotation, JPA, and EJB.

• Hibernate Documentation

o Chapter 22.1.1 Customizing the schema

• CSNS Source Code

o Model classes under src/csns/model

o Hibernate mapping files under src/hbm

[Calendar for CSNS]

Calendar is a new component of CSNS which you will develop in this quarter. In this assignment you are going to implement the model classes and the database schema based on the following requirements:

• A calendar allows users to add events and tasks, as shown in Figure 1 (click on the image to see a larger version).

• An event has a title, a description (optional), a start time, and an end time. For example, Figure 1 shows an event "CS520 Lecture" which starts at 6:10PM on 4/21 and ends at 10:00PM on 4/21. An event may also have file attachments, which could be added to the event either before the event (e.g. a flyer for a party) or after the event (e.g. the pictures taken at the party).

• An event can be public, section, or private. Any user can see the public events on their calendar, but only users who are in the same section [1] (i.e. the instructors and the students of the section) can see thesection events for that section. A private event can only be seen by the user who created it.

• Only administrators can create public events, and only instructors can create section events for the sections that they teach. Every user can create private events.

• An email reminder will be sent to the users 24 hours before the start time of an event.

• A task has a title, and is not associated with any particular time period. For example, Figure 1 shows a task "Buy grocery" - it's simply something that needs to be done, but it doesn't matter when it is done.

• A task is either open or completed. If a task is completed, the completion date must be recorded.

• A task is always private, i.e. there are no public or section tasks.

• A user can search for events and tasks based on their date, time, titles, and/or descriptions.

[Model]

Design and implement the model classes for the calendar, e.g. Event and Task. You may also need to change existing classes. The classes should be placed under the package csns.model.calendar. To receive full credit for this exercise, your classes must be sufficient to support the features described above, which you will implement in subsequent assignments. For example, to support the file attachment feature, your Event class must have some field to hold those file attachments [2].

[Hibernate Mapping]

Create Hibernate mapping files for the classes you created in the previous exercise, and place these mapping files under src/hbm/calendar. If you have changed any existing classes in the previous exercise, you need to modify their Hibernate mapping files accordingly.

Run the hbm2ddl Ant task to generate a new db/[url removed, login to view] file and check if the database schema is what you expect.

[Database Scripts]

Based on the [url removed, login to view] file generated in the previous exercise, modify the following database scripts to support the calendar functions:

• db/[url removed, login to view]

• db/[url removed, login to view]

[Notes]

1. A course taught in a particular quarter is called a section in CSNS, represented by the [url removed, login to view] class. The information about sections is stored in the sections table. A section may have more than one instructor, and this information is stored in the instructors table, from which you can obtain the instructors who is teaching or has taught a particular course. Please see db/[url removed, login to view] fo
