Exam >

The exam consist in the demonstration of command of the technologies we examined in the course. This will happen through the presentation of a final project and a discussion.

The project consist in a web application, which needs to be divided into multiple tiers. The application domain can be anything of your choice.

There must be a web tier (implemented using JEE technology), a business logic tier (implemented using EjB) and a persistency tier (implemented with a database and accessed through a persistency layer, which must be implemented using Hibernate. We expect the BL tier to be composed by both stateless and stateful beans -justification for the choices will be asked. The student will have to solve the problem of how to split the state persistency between the web and the application server, and will have to justify the choices. Sensible use of design patterns is required.

The system should show an as clean as possible separation between content and presentation.

A nice look and an attention to the user friendliness will be poitively evaluated.

The existence of transactions (or their absence) must be justified.

Sensible use of other optional technologies (whether they were discussed in the course, like XSLT, or not discussed, as Spring) is not requested but it is possible and, in case, will be evaluated.

During the exam students are expected to run the application on their machine.

The student will be asked to describe and demonstarte their system. They can be asked to explain or modify portions of their code. Questions about other technologies discussed in the course but not necessarily used in an explicit manner in the project (such as Remote Objects or XML) will be asked.

Students are rquired to send their project in a zip file to marco.ronchetti@unitn.it at least THREE days before the exam date. The zip file should include the source code, configuration files, and a report describing the project. The report should briefly describe the domain, the allowed operations, the system architecture. UML should be used whenever possible.

STUDENTS MUST ENROLL TO THE EXAM THROUGH THE ESSE3 SYSTEM!

EXAM DATES:
JANUARY 11, 11:00 AM
FEBRUARY 9, 9:00 AM

The following dates (june, july, september) will be available through ESSE3.

Section 3 e - Oct. 21 XML Exercise

You are given a xml file that contains the description of a person. You are requested to write java code to parse it using the available java for xml tools, and to create an object of class Person having two instance variables (name and age) that have to be populated by using the info available in the xml file.

Here is a solution provided by Jouke (one of your colleagues).

As a next tep you should code the viceversa (i.e. start from an instance of Person and produce a xml file that serializes its state).

You are then invited to think how this can be generalized to arbitrary classes, having an arbitrary number of instance variables. (Suggestions: provide a getter and setter method for every instance variable, and use Class.forName(), Class.getMethod() and Method.invoke(). To know more about these methods and their usage, look at the Java Reflection API tutorial and in particular at the sections about retrieving Class objects and method invokation
Note: To pass primitive values, you have to wrap them in the corresponding Object type. E.g. to call a method taking an "int", via reflection, you have to do the actual call as follows:
  setIdMethod.invoke(obj, new Object[]{new Integer(5)});
).

Also, pls take a look at some slides that show a framewok that was designed to use XML to serialize/deserialize Java objects.

Note: there is no video of this lecture, as it was a hands-on session.

Section 4 a - Oct. 23 - RMI - download slides

Note: if you missed this lecture, you can get its video:

Section 4 b - Oct. 28 RMI Exercise

In this lecture we introduced the new version of RMI (without explicit Skeleton and with automatic Stub transport). We also discussed how the parameter passing semantics is different in usual Java and in the RMI paradigm (this point can be found in the video related to the previous lecture). Then we proceeded with an exercize: a remote object should provide a simple service (as storing and retrieving a string). The exercize should be done in couples, so that you can actually try calling the remote object residing on a different machine. It is strongly advised to follow step by step a tutorial, and then start changing the code. The tutorials to be followed are: -

Hello World for RMI in Java 6

The RMI trail in the Java Tutorial

Note: there is no video of this lecture, as it was (mostly) a hands-on session.

Section 5 - Oct. 30 - Javascript - download slides

Note: the lecture will not be held in class, so you should get its video and go through it:

Also, if you were not present at the lecture of Oct 21, pls take a look at the slides about the SimpleXML framework (you can find them above, at the end of Section 3e).

Section 6 a - Nov. 4 - EJB - download slides

In this lecture we discussed a bit the concept of Directory and JNDI - you should look at the video to get a little bit deeper in this topic (and here are the slides for JNDI):

Then we started discussing the architecture of EJB, the necessity of the Home interface, the meaning of stateful and stateless session beans. We introduced EJB in version 2.1 because it better reveals the underlying model. In the next lectures we shall then see how the vesion 3.0 simplifies the programmer\'s work. This lecture was not exactly equivalent to the one given the previous year, that is recorded in the following video. However if you missed this lecture the video can still help.

ASSIGNMENT: Install and configure JBOSS. See http://weblogs.java.net/blog/ddevore/archive/2006/01/netbeans_with_j.html (It\'s a bit outdated but still useful).

Section 6 b - Nov. 7 - EJB part 2 - same slides as 6 a

Section 6 c - Nov. 11 - EJB part 3 - same slides as 6 a

Version 3.0 of EJB and practice.
After a short introduction ef EJB 3.0, we shall practice a bit with JBOSS.
No video recording of this lecture (the 3.0 part is contained in the video of the previous lecture).

Section 6 d - Nov. 18 - Entities - download slides

You should follow some tutorials:

Hibernate tutorial

if you use Netbeans, you might find this useful: Hibernate in Netbeans (you will have to ignore some stuff dealing with JSF)

if you use Eclipse, you might find this useful: Hibernate in Eclipse (The tutorial is 3 years old, but most stuff should be ok)
