ABSTRACT

Access My PC, as we call it, is a software that allows users to access devices connected

to their systems from remote locations. The process starts when the different users, who need the

facility, get registered through our website and download the application program for the said

facility. Once the software is installed on the home pc then the user can access the devices

connected to the system from any location using our website through the Internet.

A simple registration form is provided to the user wherein he can enter his name, address,

contact number, email id, login id and password. After filling up the proper information, the user

gets successfully registered for the application software. The user is authenticated for his login

name and password, which was provided to him during the registration process. If the user fails to

give his proper login id or password, an error message is displayed to him indicating that the

login id does not exist.

The user has the option for downloading the software to the particular system that he is

using. Once the system is installed in that system, say the Home PC, then the devices connected

to that system can be accessed easily using our website. Accessing the various devices connected

to the Home PC is the feature that is being implemented in the project. Every user will have a

particular Access code to be entered for getting access to this feature. If the Access code entered

INTRODUCTION

1.1 OVERVIEW OF THE PROJECT

Access My PC, as we call it, is software that allows users to access devices connected to

their systems from remote locations. The process starts when the different users, who need the

facility, get registered through our website and download the application program for the said

A simple registration form is provided to the user wherein he can enter his name,

address, contact number, email id, login id and password. After filling up the proper information,

the user gets successfully registered for the application software.

1.1.2Login and Authentication

The user is authenticated for his login name and password, which was provided to him

during the registration process. If the user fails to give his proper login id or password, an error

message is displayed to him indicating that the login id does not exist. If the login is successful

then the user is able to perform the following functions:

Software Download: The user has this option for downloading the software to the

particular system that he is using. Once the system is installed in that system, say

the Home PC, then the devices connected to that system can be accessed easily

using our website.

Access Devices: This is perhaps the purpose of Access My PC. Accessing the

various devices connected to the Home PC is the feature that is being

implemented here. Every user will have a particular Access code to be entered

for getting access to this feature. If the Access code entered is


7/40

wrong then the user get automatically logged out. Once the correct Access Code is

entered the user can access the device he wants. Logout: The user can sign out of

the login area any time using this function.

1.2 SYSTEM ARCHITCTURE

The Basic System Architecture is shown below:

Server

Remote PC Home PC

Fig 1.1: System Architecture

The System architecture has to be designed keeping all the above functions in mind. We can see

that the system consists of mainly the following three parts:

1.2.1 Home PC

Home PC is the personal computer, which is owned by the user. The software that is Application

part resides on this computer. It gets the data from the device and transmits it to the remote PC

location and it also gives the status of the remote PC location. It has no level of user

authentication. But it is the application part of this system that checks for the user device

accessing. Home PC consists of mainly five modules namely:

Network Interface: This is the part of the application, which is connected to the network.

Data Manipulation Unit: This prepares the data from the devices to suitable for the

network transmission.

Device Access Module: This gets the data from the user from the interface corresponding

to each of the users.

Internet

consists of Data Manipulation and Device Access units. These two units are controlled by a

Control unit. The Home PC is connected to a Network Interface. It is also connected with the

devices via Device Interface.

1.2.2 Server

It is the master controller of the entire software. It consists of controlling Application level

program and it gets the requests from the users of the Remote PC. It also gives the instructions to

the Home PC. Server consists of mainly 5 modules namely:

Network Interface: It communicates with the Home PC as per the instruction from

the control module. It decides the protocol for communication and also the other

network related factors.

Control Module: It controls the entire server module

Database Monitor: It constantly checks the database and sends signals to the control

module according to the state changes of the system.

1.2.3 Remote PC

Remote PC is the PC from where the user login for selecting and using a device in the Home PC.

For this he uses the http protocol. The server side programs and the client side programs are used

to make use of this Remote PC. It has the following modules:

Network Interface: It performs the network-based functions such as connecting to

server, receives and transmits the user data.

Data Manipulation Unit: In this the data from the network is converted

to their actual form and representation separates the control signals and data signals.

Control Module: It controls and coordinates the different modules. It also defines the

rules from the network. It handles the loss of data and configures the different units

for best performance.

Device Interface Regeneration: In this it creates the Graphical User Interface

according to the device and it also gives the Graphical User Interface according to the

device selected. It also receives the user inputs and responds accordingly.

COMMAND EXECUTION

Once you have registered in the website and downloaded the software in the Home PC,

you will be given a login name and a password. Using this, you can access your Home PC from

any remote system through internet. Then you will be able to do the above operations. Let's see

them in detail:

2.1. FILE MANAGEMENT

In file management section, you can do the following functions:

2.1.1 View Files:

Through this option, you can view the drives and directories of your Home PC while

you are using a Remote PC. You can also view the subfolders and files in the Home PC in a

hierarchical manner.

2.1.2 Upload Files:

In this option, you can transfer files from the Remote PC to your Home PC. The

uploaded files will be stored in a folder namely "Upload" in the Home PC.

2.1.3 Download Files:

This option enables the user to download the files from the Home PC to the Remote PC

he currently uses. The user can download files from the Home PC to the desired location of the

system that is currently in use.

2.2 DEVICE MANAGEMENT

Device management is the most enhanced option of ACCESS MY PC. With the help of

this option, the user can access the external devices attached to the Home PC. These can be

printer or webcam. The user can do the printing job in the printer that is connected to the Home

PC. Similarly, he can view the image that was captured by the webcam attached to the Home PC.

2.3. COMMAND EXECUTION

Command Execution is the option through which the user can execute commands in the

Home PC and its results can be viewed in the Remote PC. The command can be anything that can

be executed in the command prompt (eg: dir, copy icon, date, notepad etc.). The text results will

3.1. Core Java

The Java language was derived from C++ but without many of the cumbersome, difficult-

to-use features of C++. Java's cross-platform capability originally addressed the problem that

applications for embedded devices must run on a wide variety of hardware (without the benefit of

a standardized operating system). Java has taken much of the C/C++ syntax, making

simplifications and revisions to suit to its own philosophy. Java is designed to be architecturally

neutral so it can run on multiple platforms. The same runtime code can run any platform which

supports Java.

To achieve its cross-architecture capabilities, the Java compiler generates architecturally

neutral byte code instructions. These instructions are designed to be both easy to interpret on any

machine and easily translated into native machine code on the

fly.

Java has a wide range of libraries (or packages) which can be used to extend the language.

Libraries are available for user interface objects (AWT or swing variants), I/O, a network library,

etc.

great improvement over C++, Java's nominal predecessor. Indeed, initial experimental resultsshow greater programmer productivity and fewer program bugs for development with Java versus

C++.


15/40

Significant Java Features

Java is a fully object-oriented language and it can be used to:

create applets for viewing within a browser, standalone client-side application,

create standalone client-side applications

create middle-tier components (Servlets/JSP) for generating webpage with dynamic

content and parsing web pages coming back from the client

create middle tier component (Enterprise JavaBeans or EJB) for implementing business

logic and updating the database

create procedures that run within a database and are callable from other database

procedures

Java RMI

Remote Method Invocation (or RMI for short) allows us to execute methods on remote servers.

RMI is the acronym for Remote Method Invocation. As the name suggests, it helps you locate

and execute methods of remote objects.

Objects which have to be made available to other machines have to be exported to

something called a Remote Registry Server so that they can be invoked. Remote Registry Server

is a service that runs on the server and helps client's search and access objects on the server

remotely. Now, if an object has to be capable of being exported then it must implement the

Remote Interface present in the RMI package.

RMI uses something called a stub and a skeleton. The stub is present on the client side, and

the skeleton the server side. There are a number of events that have to take place beforehand

which help in the communication of the data. The stub is like a local object on the client side,

which acts like a proxy of the object on the server side. It provides the methods to the client

which can be invoked on the server. The Stub then


16/40

sends the method call to the Skeleton, which is present on the server side. The Skeleton then

implements the method on the server side.

The Stub and the Skeleton communicate with each other through something called a

Remote Reference Layer. This layer gives the stub and skeleton the capability to send data

using the TCP/IP protocol.

On the server end we associate a string variable with an object. The client tells the server

what object he wants to create by passing that string to the server, thus letting the server know

exactly what object you are talking about. All of these strings and objects are stored in the

Remote Registry Server on the server.

Remote Method Invocation (RMI) facilitates object function calls between Java Virtual

Machines (JVMs). JVMs can be located on separate computers - yet one JVM can invoke

methods belonging to an object stored in another JVM. Methods can even pass objects that a

foreign virtual machine has never encountered before, allowing dynamic loading of new classes

as required. This is a powerful feature.

The server must first bind its name to the registry

The client lookup the server name in the registry to establish remote references.

The Stub serializing the parameters to skeleton, the skeleton invoking the remote method

and serializing the result back to the stub.

responsible for sending the remote call over to the server-side skeleton The stub opening

a socket to the remote server, marshaling the object parameters and forwarding the data

stream to the skeleton.

A skeleton contains a method that receives the remote calls, unmarshals the parameters,

and invokes the actual remote object implementation

Step of developing an RMI System:

1. Define the remote interface

2. Develop the remote object by implementing the remote interface.

3. Develop the client program.

4. Compile the Java source files.

5. Generate the client stubs and server skeletons.

6. Start the RMI registry.

7. Start the remote server objects.

8. Run the client

The Remote Object

This interface (yes our remote object is actually an interface) will have only method

declarations. Hopefully you know that interfaces don't always have to have method bodies,

just declarations. The Remote Object will have a declaration for each method that you want

to export. This remote object would implement the Remote interface, which is present in the

Java.rmi package.

The Remote Object Implementation

This is a class that implements the Remote Object. If you implement the Remote Object, it's

common sense that you would override all of the methods in that object, so the remote object

implementation class would actually have all of the method bodies of the methods that we

want to export. This method will be extended from the UnicastRemoteObject class.


19/40

The Remote Server

This is a class that will act like a server to the client wanting to access remote methods.

Here's the place where you will bind any string with the object you want to export. The

binding process will be taken care of in this class.

The Remote Client

This is a class that will help you access the remote method. This is the end user, the client.

You will call the remote method from this class. You will use methods to search and invoke

that remote method.

3.2. JSP

Java Server Pages enables the development of dynamic web sites and it is based on Java

language. The simplest JSP document is a combination of Java statement and HTML tags. In a

JSP document, you can interrupt a Java statement with part of an HTML tag, or interrupt a tag

with part of a statement. We can't use ordinary English-language commands to create JSP

documents.JSP is a mix of Java and HTML needs to be translated into an ordinary HTML

document and sent to the user's Web browser.

To allow server side development JSP was developed by Sun Microsystem. Typical different

clients connecting via the Internet to a Web server. e.g. a well popular Apache Web server is

execute on Unix platform.

Java Server Pages or JSP for short is Sun's solution for developing dynamic web sites. JSP

provide excellent server side scripting support for creating database driven web applications. JSP

enable the developers to directly insert java code into jsp file, this


20/40

makes the development process very simple and its maintenance also becomes very easy. JSP

pages are efficient, it loads into the web servers memory on receiving the request very first time

and the subsequent calls are served within a very short period of time.

In today's environment most web sites servers dynamic pages based on user request. Database is

very convenient way to store the data of users and other things. JDBC provide excellent database

connectivity in heterogeneous database environment. Using JSP and JDBC its very easy to

develop database driven web application.

Fig 2.5 JSP Architecture

Java Server Pages (JSP) technology is the Java platform technology for delivering dynamic

content to web clients in a portable, secure and well-defined way. The Java Server Pages

specification extends the Java Servlet API to provide web application developers with a robust

framework for creating dynamic web content on the server using HTML, and XML templates,

and Java code, which is secure, fast, and independent of server platforms. JSP has been built on

top of the Servlet API and utilizes Servlet semantics. JSP has become the preferred request

handler and response mechanism. Although JSP technology is going to be a powerful successor to

basic Servlets, they have an evolutionary relationship and can be used in a cooperative and

complementary manner.

Servlets are powerful and sometimes they are a bit cumbersome when it comes to generating

complex HTML. Most servlets contain a little code that handles application logic and a lot more

code that handles output formatting. This can make it difficult to separate and reuse portions of


21/40

One of the main reasons why the Java Server Pages technology has evolved into what it is today

and it is still evolving is the overwhelming technical need to simplify application design by

separating dynamic content from static template display data. Another benefit of utilizing JSP is

that it allows to more cleanly separating the roles of web application/HTML designer from a

software developer. The JSP technology is blessed with a number of exciting benefits, which are

chronicled as follows:

1. The JSP technology is platform independent, in its dynamic web pages, its web servers, and its

underlying server components. That is, JSP pages perform perfectly without any hassle on any

platform, run on any web server, and web-enabled application server. The JSP pages can be

accessed from any web server.

2. The JSP technology emphasizes the use of reusable components. These components can be

combined or manipulated towards developing more purposeful components and page design. This

definitely reduces development time apart from the At development time, JSPs are very different

from Servlets, however, they are precompiled into Servlets at run time and executed by a JSP

engine which is installed on a Web-enabled application server such as BEA WebLogic and IBM

WebSphere.

3.3. HTML

HTML is a language used to develop web pages. HTML is the language interpreted by the

browser. Web pages are also called HTML documents. HTML stands for Hyper Text Markup

Language. An HTML file is a text file containing small markup tags. The markup tags tell the

web browser how to display the pages. An HTML file must have an htm or html file extension.

An HTML file can be created using a simple text editor.

HTML tags are instructions that are embedded into the text of the document. An HTML tag

is a signal to a browser that it should do something. HTML tags begin with an open angle bracket

(). The text between the start tag and end tag is the

element content. HTML tags are not case-sensitive.

HTML is not a computer programming language. It is a document mark up language.

There is a big difference. No knowledge of programming is necessary. HTML is designed to

specify how text and images are displayed or "rendered" on your computer screen. HTML

documents are generally viewed through a program called a browser. Netscape Navigator and

Internet Explorer are both browsers.

Basic Structure of An HTML Document. .An HTML document is divided into two sections.

These are the head and the body. The head is surrounded by tag. The body is

surrounded by tags.

CHAPTER 4 SYSTEM

ANALYSIS

System analysis is the process of identification of the objectives and requirements,

evaluation of alternative solutions and recommendation for a more feasible solution. In other

words, system analysis is the step-by-step process of gathering, recording and interpreting facts. It

is the reduction of an entire system by studying the various operations. It includes studying the

problems encountered in the present system and introducing a new computer system into an

organization. The main aim of analysis is to determine problem areas and decide on solutions to

reduce or eliminate them.

System analysis itself breaks into two stages. Preliminary and Detailed. During

preliminary analysis the analyst list the objectives of the proposed system. These findings come

together in the preliminary report. Once the preliminary report is approved, the system analysis

phase advances into a second stage. During detailed analysis required data and information are

collected and a detailed study is made.

During analysis, data are collected on the available files, decision points, and transactions

of the system using various tools like data flow diagram.

Feasibility Study


23/40

requested is feasible or not. The key considerations involved in the feasibility analysis are

technical, operational, and economic.

Technical Feasibility

Technical feasibility is the most important of all types of feasibility analysis. Technical

feasibility deals with hardware as well as software requirements. An idea from the outline design

to system requirements in terms of inputs outputs, files and procedures is drawn and the type of

hardware, software, and the methods required for running the systems are analyzed. Keeping in

mind of the above considerations, the resource availability at this company was observed. It was

found that the company has the sufficient resources to develop the current project; hence the

system is technically feasible.

Economic Feasibility

Economic analysis is the most frequently used method for evaluating the effectiveness of

the software, more commonly known as the cost /benefit analysis. The procedure is to determine

the benefits and savings that are expected from a candidate system and compare them with costs.

If the benefits outweigh cost, the decision is made to design and implement the system; otherwise

further alternatives have to be made. Here it is seen that no new hardware or software is needed

for the development of the system. Hence the project is economically feasible for development in

this company.

Schedule Feasibility

Schedule feasibility is concerned with the completion of the project development within

the fixed time span. It is an important factor as it can affect other factors like machine availability,

tools, cost development and delay in the development of other systems. Besides these, this project

is assigned to the student as an academic exercise to be completed within a fixed period of time.

Operational Feasibility

The purpose of the operational feasibility study is to determine whether the new system

would be used if it is developed and implemented, will there be resistance from users that will

undermine the possible application benefits etc. From the outputs of the meeting that was held

with the system users, it was found that all of them support the development of new system. The

positive response from them encouraged in building such a system.

CHAPTER 7

SYSTEM DESIGN

The most creative and challenging phase of the system life cycle is system design. The term

design describes a final system and the process by which it is developed. It refers to the technical

specification that will be applied in implementing the candidate system. It also include the

construction of program s and program testing. The question involved here is "How the problem

is solved".

System design is a transition from the user-oriented document to the document-oriented program

or database personnel. It emphasizes translating performance specification into the design

specification and it involves conceiving and planning and then carrying out the plan for

generating the necessary reports and outputs. Design phase acts as the bridge between the

software requirements specifications and implementation phase , which satisfies the requirements

7.1. MAJOR SYSTEM DESIGN ACTIVITIES:

Input Design:

Input design is a process of converting user-oriented input to computer based format. It also

includes determining the record media ,method of input, speed of capture and entry into the

system. Input design consist of developing specification and procedures for data procedure for

data preparations, those necessary steps into put transaction data into usable form of processing,

data entry and activity of putting the data into computer for processing. Five objectives guiding

the design are input focus on controlling the amount of input required, avoiding delay, controlling

error and keeping the steps simple. The following are the details the system analyst decide while

designing

The data to input

The details of how data should be arranged or coded

The data item and transaction needed validation to detect errors.

All input processes have bee designed with at most care to avoid entry of any kind of invalid data

into the system. The input screens have been validated effectively in order to give the most

accurate input details. Points to be noted while designing the input screens are

Don't overcrowd the input screen

Keep the same style among the screens

Ask for confirmation of critical data


26/40

help in decision making. Output are also used to provide a permanent hard copy for the later

consultation. They are obtained in the form of response to the requests.

Program Design :

On the analysis based on the requirement the program design taking into consideration all

program aspects. The structure require, the control flow etc are decided for efficient functioning

of the system that was to be developed

7.2 LOGICAL DESIGN

Logical design describes the format of inputs, outputs, and procedures that meets the user

requirements.

The design covers the following:

Reviews the current physical system.

Prepares the output specification.

Prepares the Input specifications.

Prepares control specifications.


27/40

CHAPTER 8 SYSTEM

DEVELOPMENT

System development is a series of operations performed to manipulate data to produce output

from a computer system. This is highly dependent on the programming language used. The

principle activities during the development phase can be divided into two major related sequences

:

1. External system development

2. Internal system development

The major external system development activities are :

1. Implementation

2. Planning

3. Equipment acquisition

4. Installation

The major internal system development activities are :

1. Computer program development

2. Performance testing

CHAPTER 9 SYSTEM

IMPLEMENTATION

The implementation stage is the next step towards the problem solution. Here the details like

which coding language is used is decided and the coding is done in the specified language.

The implementation is the practical job of putting a theoretical design in the practice. It may

involve the complete implementation of a computer complex or the introduction of one small

subsystem.

The implementation phase of a project covers the period from the acceptance of the test design to

its satisfactory operation support by the appropriate user and operations manual. It is a major

operation across the whole organizational structure and requires a great deal of planning.

Planning for implementation must begin from the initial conception of the project. It requires a

thorough knowledge of the new system, its personal needs, hardware and software requirements,

file and procedure conversion activities, etc. Only the analyst is responsible for creating the new

system will possess this knowledge. He can plan, schedule and co- ordinate but has no executive

powers.

CHAPTER 10

TESTING

System testing is the stage of implementation, which is aimed at ensuring that the systemworks accurately and efficiently before live operation commences. Testing is vital to the success

of the system. An elaborate testing of data is prepared and the system is tested using this test data.

While testing error noted and corrections are made. The users are trained to operate the developed

system. Both hardware and software securities are made to run the developed system successfully

in future. Testing steps:

S Unit Testing

S Integration Testing

Validation Testing

Output Testing

User Acceptance Testing

Unit Testing

Unit testing focuses verification efforts on the smallest unit of software design, the module. This

is also known as "Module Testing". The modules are tested separately. This testing is carried out

during programming stage itself. In these testing steps each Module is found to be working

satisfactorily as regard to the expected output from the module.

In the project, we have done unit testing to test whether the each unit works in the desired

manner.

Integration Testing

Integration testing is a systematic technique for constructing tests to uncover errors Associated

within the interface. In this project, all the modules combined, and then entire


29/40

Program is tested as a whole. Thus in the integration testing step, all the errors uncovered are

corrected for the next testing steps.

We have also done integration testing after integrating the whole system.

Validation Testing

Validation testing is where requirements established as a part of software requirement analysis is

validated against the software that has been constructed. This test provides The final assurance

that the software meets all functional, behavioral and performance requirements .The errors,

which are uncovered during integration testing, are corrected during this phase.

Output Testing

After performing the validation testing, the next step is output testing of the proposed system

since no system could be useful if it does not produce the required output in the specific format.

The Output generated or displayed by the system under consideration is tested asking the users

about the format required by then. Here, the output is considered into two ways: one is on the

screen and the other is printed format.The output format on the screen is found to be correct as the

format designed according to the user needs .For the hard copy also, the output comes out as

specified by the user. Hence output testing doesn't result in any connection in the system.

User Acceptance Testing

User acceptance of a system is the key factor for the success of any system. The system under

consideration is tested for user acceptance by constantly keeping in touch with the prospective

system users at time of developing and making for SiteDownloader system.

The testing of the software began along with coding. Since the design was fully object-oriented,

first the interfaces were developed and tested. Then unit testing was done for every module in the

software for various inputs, such that each line of code is at least once executed After all modules

were coded the integration test were carried out. Some minor errors were found in the output at

the earlier stage and each of them was corrected. In the implementation of user interface part no

major errors were found. After the software was completely developed, the testing was done.

MAINTENANCE

Development is a single activity. Maintenance is a continuous activity. Maintenance

involves activities like inspections, corrections and enhancement. Once the system is delivered

and deployed, it enters the maintenance phase. The system need to be maintained not because of

some of its components wear out and need to be replaced, but because there are some residual

errors remaining in the system that must be removed as they are discovered. This includes

activities related to debugging the software after it goes live, changes required to address evolving

software and enhancement to meet changing customer requirements. So maintenance phase

involves : Understanding the effects of change. Testing the new parts.

Retesting the old parts that were not changed Making

changes-to both the code and the documents.

These changes have to be signed by the user before the change can be carried out. Since

requirement change request involves cost, user will be cautious while requesting the software

changes. The software will require continued support. The system maintenance means the

maintenance activities after and during the system development processes. This include activities

related to debugging the software after it goes live, changes acquired to meet change in users

requirement.

Three type of maintenance :

Corrective maintenance.

Adaptive maintenance.

Perfective maintenance.

Maintenance phase identifies if there are any changes required in the current system. If the

changes are identified, then an analysis is made to identify if the changes are really required. Cost

benefit analysis is a way to find out if the change is really essential

CONCLUSION

Access My PC, in simple words, is a remote PC access software. This is done through a web site.

The user can register to the web site with a user name and password and can download the server section

of the software to his Home PC or Office PC. Thereafter, he can access his Home PC through a network

from anywhere.

The web site provides the access to the files and peripheral devices in the Home PC. The web site

also allows the user to manipulate the files and operate the remote devices such as printer or webcam. The

image captured by the webcam can be viewed by the user. Similarly, the user can do the printing jobs in a

printer attached to the Home PC.

It also provides the file viewing, uploading and downloading options to the user. The user can

execute commands in the command prompt of the Home PC and view the result in his current system.

All these provisions allow the user to access his PC from anywhere. This is an important milestone

in the enhancement of Internet. As the caption says, this software gives the user "anywhere PC access".

RESUME

The software we have developed can be used to access a PC remotely through our website while

connected to a network. This software allows the user to access his files and devices remotely. It gives a

user friendly interface to the Home PC through the network.

In future, this software can be upgraded with provisions like Remote Desktop Viewing and accessing.

Remote Desktop Architecture provides a vast area of development to the programmers. It can be also

upgraded with a video conferencing provision. All the file manipulation operations like creation, deletion,

renamig etc can be included in this website in future.
