The Car Rental System sample application
The car rental system application is one of multiple samples showing what you can do
with AndroMDA. In order to get the sources for this sample you are required to download
an AndroMDA 3.x distribution.
The model has been designed using the Poseidon case tool. You will find
the model inside this file.
Open and view this model with Magic Draw's community edition, which can
be downloaded from No Magic's web site.
Although Poseidon CE is free, not everybody has installed it. Therefore, we have
used Poseidon PE to generate an HTML/JPEG representation of the car rental system sample model
browsable as HTML.
The Model
The model consists
of a package with use cases, explaining what the main actors (users)
of the application might be and what they can do with the system.
The main actors are an administrator who creates things
like cars and types of cars, a customer who reserves cars for certain
dates, and a call center who can reserve cars as well as record
car accidents. Last, but not least, there are car loan and
reception desks who do what their names imply. :-)
Each use case has an activity diagram attached to it which explains
the message flow of that particular use case.
The rest of the model contains all the design level packages with the
class diagrams inside. The design level packages are
admins,
contracts,
customers and
inventory.
The Implementation
This sample was generated using the following cartridges:

| Persistence (Entity Beans) and Business (Stateless Session EJBs) |
EJB 2.0 (Stateless Session and Entity EJBs) |

Building and Deploying
To build the car rental system, just cd to the andromda distribution's
samples/car-rental-system directory and type maven,
this will build both EJB and Hibernate versions of the application.
You will find the deployable ear file located in
samples/car-rental-system/app/target.
This ear files can be deployed within a JBoss application server instance
(like any typical J2EE application) by dropping
the ear files within your $JBOSS_HOME/server/default/deploy directory.
Because the application uses the HypersonicSql Database bundled with JBoss,
you'll need to make sure you have JBoss running before attempting to deploy
the application.
Using
Once the car rental system has been successfully deployed within JBoss (i.e.
no exceptions), point your browser
to http://localhost:8080/car-rental-system.
You may now begin to explore the application:
-
Login as an administrator
-
Create things such as car types, cars and customers
-
Logout
-
Login as a customer and reserve the cars created from
step 2 car(s) for certain date(s).
-
Finally, you may start a JDBC browser to have a look at the
database tables with their beautiful CMR relationships in
the disguise of foreign keys
When you log in as administrator for the first time, the system will prompt
you for a new username and password. Please memorize these for the next
time you log in.
