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.

Servlet is a Java class that runs inside the container. It allows you to process the HTTP request and generate dynamic web pages, but it's more Java then HTML like you need to code HTML inside Java, which is both erroneous and not recommended. Servlet is mainly used as a Controller in web applications created using the MVC design pattern. One of the famous examples of that is the DispatcherServlet of Spring MVC framework, which acts as a front controller. Its job is to receive request and process it, but the view generate or dynamic web page generation functionality is passed down to JSP. Though it provides the data that need to be shown in JSP, which makes the view part of the Model View Controller (MVC) design pattern.

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.
