Assignment
6: Other Patterns - Lab (4%)
This assignment
relates to the following Course Learning Requirements:
CLR 1 -
Implement an objected-oriented program design incorporating the use of best
practice design patterns using the JAVA programming language.
CLR 3 – Develop
an application thru the use of refactoring steps which culminate in the
demonstration of the Model-View- Controller or modified Model-View-Controller
design pattern.
CLR 4 – Develop
web applications using Java.
Objective of this
Assignment:
The objective of
this assignment is to demonstrate the skills required to:
- Design a web-based Java
application using both sever-side and client-side programming.
Instructions
To prepare you
for this assignment, read the module 11 and 12 content and follow the embedded
learning activities.
Tasks:
- The first task of this assignment is to
read the scenario below. It is a continuation from the previous
assignment.
Code&CodeScenario
Code&Code is
a small company dedicated to Software Development. Their engineering team, to
which you belong, is working on writing a Web Application as an MVP for a new
customer.
The code name
for this App is “Loggy”, which is meant to offer functionality for a personal
journal where users can log their daily activities through text, voice and
video.
Your team was
assigned to write the main functionality, which is essentially a
Microblogging System where all the posts can be annotated with voice, video,
images or text.
In your third
iteration you created a web application that would be the foundation for the
Microblogging System under the following assumptions:
- Users submit their
logging activity through a web page to a single thread in the same way
Twitter users submit their posts. A form containing an input box and
submit button is shown at the top and under that, a list with all the
previous submissions ordered by the timestamp in descending order.
- A short title (60chars) and a short
description (120 chars) is required. After that, the user attaches the
actual content, which can be a text, picture, audio or video file.
- The file is processed in the server
and a thumbnail is shown right below the description.
|
- Once you have familiarized yourself with
the scenario provided above, you must review the code from the previous
iteration (provided) and proceed with code refactoring by applying Design
Patterns in order to improve the general design.
MVC Pattern
The application renders HTML
directly from the Servlet. While this approach was good enough for a quick
prototype, it would not scale.
- Apply the MVC pattern by
templating the View using JSP pages.
- Customize the CSS styling
with a design of your choice.
Submission:
Your submissions
for this assignment should include:
- Java code of your final
solution.
- Report of your
observations on the changes you had to do to your code while following the
recommended steps. Add snippets of code to the report to show intermediate
steps.
*Remember that
although the scenario and resulting model may be used for future activities,
the main goal is to practice what you have learned in the modules 11 and 12, so
do not be worried about finding the perfect solution for this case. Going
beyond the scope of these two models is optional and will not be taken into
consideration for the grades.
Guidelines
- Once you have completed all steps and
followed submission requirements, post your assignment in the designated
attachment section in Brightspace when your facilitator assigns it. Check
the course modules and weekly schedule for instructions.
- The submission consists of four separate
files.
- A WAR file optimized for Tomcat 9
thatincludes the source code, static resources and
dependencies.
- A DDL file containing the Database
description for the project (unless you have opted for adding code for
auto-generating the database if it does not exist).
- A MP4 file with a screen capture
demonstrating how your application works in at least two browsers
including Chrome. The recording does not have to include voice over and
should be between 1 and 2 minutes only.
- A DOC file containing your report.
- The project provided makes use of MySQL,
you must keep it that way. The database should be named as
lab6_STUDENTNUMBER. And if the username is hardcoded, the name used should
be “root” with no password. Otherwise specify in the submission where the
database name, username and password should be configured.
- All files should be named as
Assignment_NUMBER_STUDENTNUMBER.extension
(Where extension means docx, mp4, zip etc, not the word extension)
Ensure you
properly cite any work that is not yours in your submitted documents, including
code.
Code to follow:
Log.java:
package com.algonquin.loggy.beans;
import java.util.Date;
import java.util.UUID;
public abstract class Log {
private UUID id;
private String title;
private String content;
private Date createTimestamp;
public Log() {
}
public Log(String title, String content) {
this.id = UUID.randomUUID();
this.title = title;
this.content = content;
this.createTimestamp = new Date();
}
/**
* @return the id
*/
public UUID getId() {
return id;
}
/**
* @param id the id to set
*/
public void setId(UUID id) {
this.id = id;
}
/**
* @return the title
*/
public String getTitle() {
return title;
}
/**
* @param title the title to set
*/
public void setTitle(String title) {
this.title = title;
}
/**
* @return the content
*/
public String getContent() {
return content;
}
/**
* @param content the content to set
*/
public void setContent(String content) {
this.content = content;
}
/**
* @return the createTimestamp
*/
public Date getCreateTimestamp() {
return createTimestamp;
}
/**
* @param createTimestamp the createTimestamp to set
*/
public void setCreateTimestamp(Date createTimestamp) {
this.createTimestamp = createTimestamp;
}
}
