This Java Servlets course by Uplatz provides a comprehensive knowledge of the subject. You will learn each and every feature, functionality, usage and configuration of Java Servlet with practical examples. It is a self-paced video lectures based course. You will be awarded Course Completion Certificate at the end of the course.
A java servlet is a java programming language used to extend the capabilities of a server to handle the complex request obtained from the webserver. Servlet is fast as it doesn’t create a new process every new request received. It is a server-side component, so inherits the security provided by the webserver.
In this modern era, where everything is becoming digitalized, a billion types of data generated on a day-to-day basis, there is a need to create dynamic web pages with the capability to change the content in accordance with the business or demand in the market. This can be done using Java Servlet.
Services provided by Java Servlets are network services, decode and encode MIME-based message, resource management, scarcity service and session management. 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. Java Servlets are used to create a web application (resides at server side and generates a dynamic web page). Servlet technology is robust and scalable because of java language.
In essence, a servlet is basically 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. For such applications, Java Servlet technology defines HTTP-specific servlet classes.
The javax servlet and javax servlet http packages provide interfaces and classes for writing servlets. All servlets must implement the Servlet interface, which defines life-cycle methods. When implementing a generic service, you can use or extend the GenericServlet class provided with the Java Servlet API. The HttpServlet class provides methods, such as doGet and doPost, for handling HTTP-specific services.
Java servlets are the first step to understanding web programming using Java, and this Java Servlets course will show you the basics of servlet architecture and applying filters to more complex issues like debugging and deployment.
