WEB APPLICATION    

     A web application is any application that uses a web browser as a client. The application can be as simple as a message board or a guest sign-in book on a website, or as complex as a word processor or a spreadshee The 'client' is used in client-server environment to refer to the program the person uses to run the application. A client-server environment is one in which multiple computers share information such as entering information into a database. The 'client' is the application used to enter the information, and the 'server' is the application used to store the information.

 

 BENIFITS OF WEB APPLICATION

    A web application relieves the developer of the responsibility of building a client for a specific type of computer or a specific operating system. Since the client runs in a web browser, the user could be using an IBM-compatible or a Mac. They can be running Windows XP or Windows Vista. They can even be using Internet Explorer or Firefox, though some applications require a specific web browser.

FEATURES OF WEB APPLICATION

    Most web applications are based on the client-server architecture where the client enters information while the server stores and retrieves information. Internet mail is an example of this, with companies like Yahoo and MSN offering web-based email clients.

FUNCTIONS   

 Web applications can provide the same functionality and gain the benefit of working across multiple platforms. For example, a web application can act as a word processor, storing information and allowing you to 'download' the document onto your personal hard drive.

WEB APPLICATION TYPES

A web application is a dynamic extension of a web or application server. There are two types of web applications:

  • Presentation-oriented: A presentation-oriented web application generates interactive web pages containing various types of markup language (HTML, XML, and so on) and dynamic content in response to requests.
  • Service-oriented: A service-oriented web application implements the endpoint of a web service. Presentation-oriented applications are often clients of service-oriented web applications.

WEB CONSTRUCTION     

    Servlets are Java programming language classes that dynamically process requests and construct responses.JSP pages are text-based documents that execute as servlets but allow a more natural approach to creating static content.

    Although servlets and JSP pages can be used interchangeably, each has its own strengths. Servlets are best suited for service-oriented applications (web service endpoints are implemented as servlets) and the control functions of a presentation-oriented application, such as dispatching requests and handling nontextual data.

 

WEB COMPONENTS   

    In the Java 2 platform, web components provide the dynamic extension capabilities for a web server. Web components are either Java servlets, JSP pages, or web service endpoints.

    The client sends an HTTP request to the web server. A web server that implements Java Servlet and JavaServer Pages technology converts the request into an HTTPServletRequest object.

    This object is delivered to a web component, which can interact with JavaBeans components or a database to generate dynamic content. The web component can then generate an HTTPServletResponse or it can pass the request to another web component. Eventually a web component generates a HTTPServletResponse object. The web server converts this object to an HTTP response and returns it to the client.
