Abstract
In this project, I am planning to develop a plug in module that can be integrated into the web based application. The aim of this application is to provide email-services, calendar services and chat services dynamically within the browser. I am responsible for developing Chat Service and Calendar service. For example, in Google apps, the user can open the Gmail and while working on this, the user can see the friends who are online without changing a window or logging into another chat messenger and also will be able to open the calendar and see the contents. In a single browser window, the user is able to view and modify the different applications dynamically. The client-side/web browser technologies used in Web 2.0 development are JavaScript and Ajax (XML). Ajax programming uses JavaScript to upload and download new data from the web server without undergoing a full page reload. Chat service is developed using Java and Ajax technology and the Mysql database. It has all the basic features that we see in general popular chat applications like Yahoo chat or Skype. Java technologies and Ajax framework makes the application more scalable and compatible to integrate with other application. The GUI part is greatly enhanced for better end user experiences. Calendar service application is provided with some of the basic features, such as ability to schedule one or more events on a particular day, a standard view that can show any month, with event times and titles listed in order and users will be able to open the application like any other application.
