“Blogger Site” project has been undertaken for the fulfillment of the

B.C.A. (6 Th Sem.) Project, this is the JAVA based website using

technologies like Java Server Pages, Servlets, JavaBeans, Struts, Custom

Tags, Applet. And backend using the oracle9i.The website will be hosted

on Apache Tomcat web server.

My special thanks go to “Er.Pushkar Nath Tripathi” project

development who provided me sample ideas when I got stuck during the

project. They also helped me to collect all the relevant Information. They

also helped me in designing GUI user interface & restricting Input/Output

section of the software.

2.2 Objective


Object Oriented Programming System:-

The fundamental concept of Object-Oriented Programming is that it

allows combination of data and functions/methods/procedures which are

working on that data, which did not exist in earlier procedure, based

programming paradigms. Object-Oriented Programming and Design is all

about objects. An object has a well –defined interface, which is the only

way to access the object’s data. The data is thus well organized and

hidden. Such hidden data is referred to as encapsulated. Data

encapsulation and data hiding are basic and a key term used in OOPS. An

Object-Oriented Program is a collection of objects for solving a problem.

An object can be considered to be a variable that stores data and can

perform operation on the stored data itself. These objects send message to

each other. A message can be equated to a request to call a function of the

receiver object. Each object can be related to a type, which is its class. An

important consideration of a class is that it specifies the message interface

that is the message that can be sent to that type/class of the objects.

3: Project Category


Backend Tool: - Oracle 9iOracle is the widely used database in the world it runs on virtually every

kinds of computer. It’s function virtually identically on all these

machines, so we learn it on one, we can use in on any other. This type

makes knowledge oracle users and developers very much in demand, and

makes our oracle knowledge and skills very portable.

Oracle uses a variation of SQL called PL-SQL.This is a very

powerful language allowing for all conventional SQL statements, to

systems for defining new Data types, defining functions, triggers.

Front end Tool: - JAVA

Java is a platform independent, interpreted language from Sun

Microsystems. Java is a fully object oriented language providing facilities

for multithreading, network programming, database connectivity, etc.

Java has syntax reminiscent of C++ and removes the confusing and error

prone parts. Unlike C++ java have no facilities for pointer manipulation

and is completely object oriented.

7

4: Tools / platform


Java is not compiled to executable code and instead is compiled to an

intermediate format called byte code file that interpreted and run by a java

virtual machine.

The salient feature of java is:-

1. JAVA IS MULTITREADED: - Multitasking is the ability to have

more than one program working at what seems like the same time.

Multithreaded programs extends the idea of multitasking by taking it

one level lower individual program will appear to do multiple tasks

the same short for thread of control programs that can run more than

one thread at once are said to be multithreaded.

2. JAVA HAS EXTENSIVE NETWORKING CAPABILITIES: - The extensive networking facilities of java in the java .net packages

are the most powerful that any language has got to offer. The

various constructs like server socket, socket etc. offer extensi9ve

networking facilities.

3. JAVA HAS EXCELENT DATABSE CONNECTIVITY FACILITITES:-The database connectivity package of java namely JDBC (JAVA

DATABASE CONNECTIVITY) was the pioneer in providing a

consistent database connectivity system across different databases.

These classes are part of the java.sql package. Some of the classes

provided are connection, resultant, diver manager, statement etc.

8


COMPILATION AND EXECUTION OF JAVA APLICATION:-When we compile a java application to java compiler (java), it is

compiled to binary machines code rather; it is converted to class file. To

execute these class file, SUN MICROSYSTEM provide us java

interpreter.

JAVA SERVER PAGES: - Java Server Pages provide a means for

mixing HTML and Java in a single page. Inside Tomcat JSP pages should

be placed in the top-level Web application directory or in a subdirectory

with any name other then WEB-INF or META-INF. Servers are

prohibited from serving files from WEB-INF or META-INF to the user.

When you register a Web application,

JAVA BEANS :- Java Beans are reusable Java Components which are

used to implement the presentation and business logic of an application.

The website will make extensive use of these features to implement the

display of books, the display of shopping cart, etc.

CUSTOM TAG S:- Custom Tags provide means for implementing

reusable features which can be reused in much the same way as basic

HTML Tags. These are used to reduce the overall complexity of the site.

SERVLET :- Java Servlets are run on the web server and will be used to

provide support in Model view Architecture scenarios in the site where

beans, tags, and struts are concerned.

XML :- XML will be used to store data on the client side.XML provides to

creates an own tag.

APPLET:- An applet is a window-based program .As such ,its

architecture is different from the so-called normal, console-based

10


Programs. The applet class is contained in the java. applet package.

Applet contains several methods that give you detailed control over the

execution of your applet. In addition, java. Applet also defines three

Interfaces: Applet Context, Audio Clip, and Applet Stub. The most trivial

applets override a set of methods that provides the basic mechanism by

which the browser or applet viewer interfaces to the applet and controls

its execution .four of these methods –init(),start(),stop() and destroy()-are

defined by Applet. Another paint (), is defined by AWT component.

The origin of most software system is the need of someone who either

wants to automatic an existing manual system or desires a new software

system. The software system it self is created by the developer. Finally

the completed system will be used by the end users and the developers.

So me how the requirements for the systems that will satisfy the needs of

the clients and the concerns of the users have to be communicate to the

developer. The problem is that the client usually does not understand

software development process and the developer often does not

understand the client’s problem and his/her application area. This causes

a communication gap between the parties involved in the development

project.

A basic purpose of the software requirement specification (SRS)

is to bridge this communication gap.SRS is the medium through which

the client needs are accurately specified indeed SRS forms the basis of

software development. A good satisfy all the parties, something very hard

to achieve and involving trade offs

and persuasion.

A general structure of software requirement specification of my project is

given below:-

5:- Requirements

5.1:-Functional Requirement

Whenever a project is decided to be build, then before

implementation process, one of important of phase of project

requirement phase knows functional requirements of determined

project. Function requirement phase emphasize on detail

documentation of all those modules which will meet during

development of project. A project can be implemented successfully

only when, we have clear process logic of all functionally dependent

or independent modules, which make a complete project.

During this project (“Blogger Site”) development, it has been tried

to have knowledge about all functional modules like registration of

new user, study through online. Some of these modules in project

are dependent on other module and some of them are independent of

functionality of other module development.

21


5.2:- Technical Requirement

OVERVIEW: The developer has following responsibilities:

(a) Developing the system according to real life needs such that it can

meet all type of user needs.

(b) Developing the system in such a way that it can support all browsers

used by clients.

(c) It should be developed in preplanned technical views under the most

experience project manager.

(d) Conducting any training that might be needed for using the system.

(e) Maintaining the system for a period for one year after installation

PRODUCT PERSECTIVE: The web application provides a platform

through which study through “online education system”.

USER CHARACTERISTICS:- From user point of view, if any one who

wanted to study, lecture note ,study material etc. can easily access through

online education system.

.

Implementation methodology

The goal of any development effort is to produce some useful

Product. A development process is a set of activities together with an

ordering relationship between activities, which if performed in a manner

that satisfies the ordering relationship will produce the desired product. A

Process model is an abstract representation of a development process.

To solve actual problems the software engineer or a team

of engineer must incorporate a development strategy that encompasses the

process, method and tools the generic phases (correction, adaptation,

enhancement and prevention). This strategy is often referred to as process

model or software engineering paradigm. A process model for software

engineering is chosen based on the nature of the project and application,

the methods and tools to be used, and the controls and deliverables that

are required.

As the development process specifies the major development and

quality assurance activities that need to be performed in the project, the

development process really forms the core of the software process. The

management process is decided based on the development process.

Due to the importance of development process, various models have

been proposed e.g. Water Fall Model (Linear Sequential Model), Spiral

Model.

8:-Network Architecture


9:- Security Mechanism

9.1 :- Limitation of the project

Since user name and password should be stored in oracle 9i database. The only possible security based on security of data base.

Since all file is store on the file system of compute any use and any movement can delete the file.

9.2:- Future Scope of the Project:-

We can add video conferencing in our project to make the project

more effective.

With Java Enabled Phones available everywhere this project can be

made mobile enabled so that users can avail of the available facilities

on their mobile sets.
