Abstract—Examination System was necessary to separate
teaching and testing. A web-based Examination System was
developed with Java Web technologies. The system provided
the functions, including question management, paper
generation and test online. Also the combination of client-side
programming and server-side programming techniques were
used and analyzed.

I. INTRODUCTION
Examination System was helpful to separate teaching and
testing. It promoted teacher to make the lesson planning and
teach in the class carefully. It was also an important means of
evaluating the teaching effect. Otherwise, it stimulated
students to conscientiously study and attend a lecture, to do
their homework independently. Therefore, the Examination
System could improve the teaching level by providing better
technical support.
Within the Examination System we developed, the
teacher could set the score and number of different types of
question according to their need. And then, the Examination
System generated an exam paper randomly in accordance
with the requirements. Finally, the paper in standard format
and its answer could be outputted.
Taking into account the development of course content,
the Examination System could easily update and add
questions, to make the teaching content developing with the
technology synchronously.
The Examination System also provided online testing
capability for students. Students could log in the system at
any time in the campus network, test themselves, understand
their learning level, and adjust their learning progress.
II. DESIGN OF ONLINE EXAMINATION SYSTEM
A. Model 1 in JSP
Browser/Server model was an important network
application development model. It was a special kind of
Client/Server model, which used standard Web browser as
Client-side, and Web Server as the Server-side. In
Browser/Server model, the main business logic of program
was implemented on the server side. Such application called
Web application, had the advantages of good reusability and
Easy maintenance [1]. Our Examination System was
developed with JSP, and runs on the campus network. It was
called online examination system.
JSP had become the main technology to create Web
applications, because it was easy to master and could achieve
rapid development. There were two types of building models
JSP developing, respectively called Model 1 and Model 2. It
was easily to combine with business logic (jsp:useBean), the
server-side process(jsp:scriplet) and HTML(<html>) in the
JSP page. Therefore, it could be implemented to place
display, business logic and process control in a JSP page,
which result in rapid development of application. There was
a large number of small-scale Web applications constituted
by a group of JSP pages. The JSP-centric development
model was called JSP model 1[2]. The architecture of JSP
Model 1 was shown in Fig. 1.
B. Architecture of Online Examination System
Fig. 2 was the system structure of online examination
system, which was designed based on Model 1. In the system,
Web browser was used as client, JSP Engine as the business
logic tier to achieve its function, and database system as the
data layer.
(1) Client: Client was Web Browser, which implemented
the system's display logic. The function was to send request
to Web Server (including JSP Engine) through the Web
browser by users (teachers or students). While Web Server
return the requested HTML pages or HTML pages
dynamically generated by JSP page to the client, which were
shown in the Web browser.
2) Business Logic Tier: Business logic tier was achieved
mainly by JSP and JavaBean running in the JSP Engine. It
responded to client requests and achieved the business logic
with the Web Server. Tomcat, an open source software, was
used as the JSP Engine and Web Server.

(3) Data Tier: Data tier was realized with database system,
used to store the business data such as questions and papers
and control data such as user data. MS ACCESS was used to
achieve the data tier.
The JSP development model based on Model 1 is very
suitable for quick and small scale application development.
III. FUNCTIONS OF ONLINE EXAMINATION SYSTEM
A. Function Module of Online Examination System
Fig. 3 was the function module diagram of online
examination system. There were three modules in the system,
including question management, paper generation and test
online.
B. Functions of Online Examination System
1) Question Management: The functions of this module
were querying, adding, deleting, and modifying the questions.
2) Paper Generating: The function of this module was
randomly generating exam paper according to specified
requirements. It was the core function of online examination
system. The system randomly extracted questions from the
question database in accordance with three restrictions,
including question type, difficulty and chapter to generate an
exam paper.
Here the term Paper Structure was a set of specified score
and number of different types of question, which constituted
a paper. There were five types of question, including false
question, multiple choice, short answer question, cloze
question and programming question. User could freely set a
Paper Structure according to their needs. That meant to set
how many types of questions used in a paper, how many
questions and how many score for each type. The only
restriction here was that the total score must be 100 points.
For example: A Paper Structure may include 10 false
questions, each 1 point; 10 multiple choice questions, each 2
points; 2 short answer questions, each 5 points; 3 cloze
questions, each 10 points and 2 programming questions, each
15 points.
The term Paper was a paper generated by extracting
questions from the question database in accordance with a
Paper Structure. A Paper consists of a sequence of questions,
which formed the paper.

3) Test Online: Student user could use the function of
test online to randomly select a paper or use a paper
designated by teacher, and login the system at any time
within the campus network, self-test online, and understand
their learning level.
IV. KEY TECHNOLOGY IN IMPLEMENTATION OF ONLINE
EXAMINATION SYSTEM
In test online module, the function on online answering
was achieved with HTML forms in the answer page. Here it
was necessary to implement five types of submit, including
going to next question, going to previous question, going to
specified question, going to rating and going to answering.
These functions should be submitted to different pages, but
there was a function to save the user’s answer of current
question that should be achieved in all submits. To do so, the
form should be submitted to one page to save the user’s
answer, and then forward to corresponding next page. It was
important to distinguish which button made submit when the
server received.
To implement this feature, a technology combined with
client-side JavaScript and server-side JSP was used. On the
client side, a JavaScript function was binding with each
submit button. Before submitting to server, the
corresponding parameter was set to a certain value firstly.
And on the server side, JSP technology was used to
distinguish which made the submission according to the
parameter value, and then make the appropriate process.
Here is sample code.
Client-side code:
<script language=”javascript”>
function examing()
{
var next =document.getElementById("nextQNo");
next.setAttribute("value",999);
return true;
}
</script>
<form …>
…
<input type="submit" value="ANSWERING"
onclick="return examing()"/>
</form>

Serve-side code
<%
…
if (nextQNo.equals("999"))
{// set the status to answering, forward to answering
page
session.setAttribute("userStatus","answering");
response.sendRedirect("doExam.jsp);
}
%>
V. SUMMARY
JSP Model 1 development model was used to develop
online examination system, with the combination of client-
side and server side development technology. There are such
functions as question management, paper generation and test
online, which gave good aids for teachers to organize
examination and students to study the course.
