Abstract

• Online applications based on the HTTP protocol
  are shifting from wired networks, known as Web
  applications and Web services, to wireless
  networks, known as wireless mobile online
  applications
• Due to the rapid growth of mobile devices, such
  as Personal Digital Assistants and cell phones.
• Among the enabling technologies, J2ME is the
  dominant and the most potential one for building
  up these wireless mobile online applications.
• This project presents a framework that makes the
  modeling, implementation, and maintenance of
  wireless mobile online applications intuitive and
  easy.

Interdiction

• Wireless communication eliminates the
  limitations of location and time. Mobile devices,
  such as, Personal Digital Assistants (PDAs) and
  cell phones, plus the wireless networks have
  provided a solid foundation for the ubiquitous
  computing.
• Today, the number of people accessing the Web
  through wireless devices has been larger than the
  number of people who access the Web through
  desktop computers.
• Cell phones plus wireless communication have
  been part of our daily life. Definitely, they are
  not only available for voice talks but also are
  the most suitable platform for accessing online
  applications.

Objective

• To Provide a way to access Online Applications
  by Wireless Communications.
• Eliminates the limitations of Location And Time.
• To maintain Wireless Applications Intuitive and
  easy.

Modules

• There are three modules
• J2ME Module.
• User Designing Module.
• Server Side Processing Module.

8
1.J2ME Module

• The J2ME supports programming in mobile devices,
• Such as PDAs and cell phones.
• The J2ME module contain different types of
  hardware in Mobil devices
• I, The connected Device Configuration
  (CDC) and
• ii, Connected Limited Device
  Configuration (CLDC)
• This are provide common part of APIs and leave
  device specific needs features called mobile
  information device profile (MIDP).
• In this module the APIs provide by J2ME forms a
  class hierarchy
• They are categorized as high-level and low level
  user interfaces.

9

• The high-level APIs takes the screen class as its
  root,
• Which has four sub-classes, namely list, text
  box, form and alter
• We get the output in Mid let only i.e J2me
  application.
• In this module we will be dealing some packages
  like
• javax.microedition.rms.
• Javax.microedition.midlet.
• From here we have a connection to the server side
  processing

10
2.User Designing Modules

• All presentation logic is done here.
• This is also called as designing.
• We import a package called
• javax.microedition.lcdui.
• This package is used to develop the GUI part in
  J2me.
• We use so many components like
• TextBox,
• TextField,
• Choice Group etc.

11
3.Server side processing Module

• The Server side processing takes in the Apache
  Tomcat server.
• It is also Called as Request Processing
• Here there will be the servlets which handles all
  the requests, so it is called as Request
  Processing.
• Here we implement the Business Logic i.e through
  the Model.
• Model deals with the database connectivity and
  queries.

12
Requirements
Software Requirements

• Java
• J2ME
• MySql
• Tomcat5.0

System Requirements

• 3.56GHZ Processor
• 40 GB Hard disc
• 1 GB RAM

Conclusion
The MVC diagram models a wireless mobile online
application. This framework decomposes a complex
online application into modules. Each module is
a plug-and-play unit. The MVC diagram
facilitates the (OCP) open Closed principle,
which makes the software with a strong
adaptability and a high degree of
flexibility. We can further apply the framework
to more practices, improve its structure, and
enrich the libraries. Several more complicated
applications, for example, an online bookstore,
an online ticket office, an online IT
terminology, an online conference submission
systems are being developed for the goal.
