Part 2



You now should have the following items completed:



(a)

A Use case diagram(s) for the above requirements

(b)

UML Class Diagram for a model to capture the above information. This diagram
should have the attributes and method of the main elements of the
above
requirements

(c)

An implementation in java of the class diagram.

(d)

An ERD diagram of the access database that you intend to use

(e)

A html prototype of the web site

(f)

DAO objects to insert, remove and update to your database.

(g)

Tests for each of the DAO’s.


You no
w have to implement a fully functional web application. But before this
happens, you realise that you need to improve the robustness and scalability of the
existing project.

To do this you will need to:




Create your own class for handling database connect
ions, the
DBConnectionFactory class. This class will pool database connections, get its
connection settings from a properties file and will have a method
getConnection

to return a database connection object. This class must operate
as a singleton, so a
get
Instance

method must be included. Synchronisation
issues must be taken care of.



The application needs to log all database accesses and allow support people to
manage the application. Use a java logging framework to send all relevant
output to a log file.



There has been a couple of changes in requirements from phase 1, so here is what the
requirements are for phase 2:




When users log in, there name must appear at the top of each page they visit.



If they try to access a page when they are not logged in,
they will be forced
back to the login page.



Add a search box where users can search across the entire site



Add a global error page



Add an AJAX (asynchronous java and xml) element to make your application
more eye catching



Add javascript validation to make
the application more robust.



Error messages/general messages should be centralised in a single message
file.





What to do:




Make the technical changes required above



Rename your .html files to .jsp files.



Create a web project in NetBeans and copy in your

.jsp and your .java files



As you require it, make changes to your DAO’s to support the functionality
required.



Try to reduce the amount of java code that is in the JSP’s. If more than one
database access is required inside a transaction, create a Manager

class which
carries out the DAO accesses.



Use javascript where necessary.


Deliverables


You should hand up a cd which contains the following:

1.

All java code, JSP pages, cascading style sheets etc.

2.

Instructions on how to run application in readme.txt,
with the names/student
numbers of group with responsibilities.

3.

Word document, called testplan.doc which describes the expected/actual test
results (should match the use cases)

4.

ERD diagram

5.

db.doc file, which lists the tables, columns, datatypes and explains

the
function of each column


What do you get marks for:



Good design



Neat, efficient readable code/jsp’s



Well presented and accurate documentation



Robust web site (bug free)
