Description

A Servlet is a Java Programming language class that is used to extend the capabilities of servers that host applications accessed by means of a request-response programming model. Although servlets can respond to any type of request, they are commonly used to extend the applications hosted by web servers. It is also a web component that is deployed on the server to create a dynamic web page.

Servlet Technology resides at server side and it generates dynamic web page, used to create web application. Java Servlets are programs that act as a middle layer between a requests coming from a Web browser / HTTP client and databases or the applications on the HTTP server.

Before servlets, we had CGI i.e. Common Gateway Interface. It is a standard way for a Web server to pass a user's request to an application program and receives the response to forward to the user. When the user requests a Web page, the server sends back the requested page. However, when a user fills out a form on a Web page and sends it in, it is processed by an application program. The Web server typically passes the form information to a small application program. This program processes the data and sends back a confirmation message. This process of passing data back and forth between the server and the application is called the common gateway interface (CGI). It is part of the Web's Hypertext Transfer Protocol.

This practical, application-oriented Java Servlets training by Uplatz teaches Java Servlets technology and shows how to use it to develop simple to complex web applications. It is intended for both the beginners as well as experienced Java (J2SE) programmers who want to build web applications or J2EE components and systems.

The Java Servlet course begins with an overview of server-side Java programming and web protocols. Then students learn the Java Servlets architecture, the request/response cycle, and servlet life cycle, and how to build interactive web applications that parse and/or generate HTML forms. Several prominent patterns for servlet application architecture are considered. Sessions are studied as a means to developing sophisticated client/server conversations over several HTML pages. Multi-tier applications are developed using servlets and JDBC for access to relational databases.

This Java Servlet training develops the important concept of the separation of programmatic and declarative development: use of configuration and context information in lieu of hard-coded values, resource locations, etc., to make the web application as portable and easy to administer as possible. The course introduces JavaBeans as a standard for business and data objects that can be shared among servlets and JSPs, and develops techniques for sharing such objects at session scope or by request forwarding. Finally, students learn how to implement filters to adapt existing servlets by pre- and post-processing the request and response.

What you will learn in this Java Servlets course

Understand and appreciate the role of Java Servlets in the overall Java 2 Enterprise Edition architecture, and as the best Java solution to HTTP application development

Use request and response objects provided to a servlet to read CGI parameters and to produce an HTML response

Develop interactive web applications using HTML forms and servlets

Manage complex conversations with HTTP clients using session attributes

Understand the role of JDBC in Java persistence code, and use JDBC for persistence in servlet applications

Preserve portability and ease of administration for a servlet application by parameterizing servlet code, using initialization parameters, properties files, and JNDI

Use JavaBeans classes to share complex business data between components

Implement filters to adapt existing servlets with new features, and to maximize the decomposition of logic between vertical business functions and horizontal facilities

Understand and manage HTTP sessions in a web application

Create servlet filters and listeners

Write pages created with JavaServer Pages technology (JSP pages)

Create easy-to-maintain JSP pages using the Expression Language and theJSP Standard Tag Library (JSTL)

Use integrated development environments (IDEs) and application serversfor Java EE development and deployment

Write servlets using the Java programming language (Java servlets)

Java Servlets: Servlet Architecture

The Java Servlet architecture includes communication interface, protocol used, requirements of client and server, the programming with the languages and software involved. Basically, it performs the below-mentioned tasks.

First, it reads the explicit data sent by the clients (browsers). This data can include an HTML form on a Web page, an applet or a custom HTTP client program. It also reads implicit HTTP request data sent by the clients (browsers). This can include cookies, media types and compression schemes the browser understands, and so forth.

After that, the servlet processes the data and generate the results. This process may require communicating to a database, executing an RMI, invoking a Web service, or computing the response directly.

After processing, it sends the explicit data (i.e., the document) to the clients (browsers). This document can be sent in a variety of formats, including text (HTML or XML), binary (GIF images), or Excel formats.

Finally, it also sends the implicit HTTP response to the clients (browsers). This includes telling the browsers or other clients what type of document is being returned
