Java Servlet

A Java servlet is a Java program that extends the capabilities of a server. Although servlets can respond to any types of requests, they most commonly implement applications hosted on Web servers. Such Web servlets are the Java counterpart to other dynamic Web content technologies such as PHP and ASP.NET.

A servlet is a Web component that is managed by a container and generates dynamic content. Servlets are Java classes that are compiled to byte code that can be loaded dynamically into and run by a Java technology-enabled Web server or Servlet container.

Java Servlets are server-side Java program modules that process and answer client requests and implement the servlet interface. It helps in enhancing Web server functionality with minimal overhead, maintenance and support.

A servlet acts as an intermediary between the client and the server. As servlet modules run on the server, they can receive and respond to requests made by the client. Request and response objects of the servlet offer a convenient way to handle HTTP requests and send text data back to the client.

Since a servlet is integrated with the Java language, it also possesses all the Java features such as high portability, platform independence, security and Java database connectivity.
