Servlet

A servlet is a Java 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, a servlet is a way to process or transform the HTTP request into the response.

What is servlet example?

A servlet is a Java class that is used to extend the capabilities of a server. Although servlets can respond to any type of request, they are commonly used to extend the applications hosted by web servers. For example, a servlet might be used to process data submitted by a web page form before forwarding the results to a web page.

What is servlet and JSP?

A servlet is a Java program that runs on a server, usually in a container like Tomcat or Jetty. Servlets are used to handle requests from clients, usually web browsers.

A JSP (JavaServer Page) is a type of servlet that is used to generate HTML pages. JSPs are typically used to display information from a database, or to provide a user interface to a web application.

What is difference between servlet and JSP?

A servlet is a Java 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. Thus, servlet technology is the foundation of Java's web platform.

A JSP (JavaServer Page) is a text-based document that contains two types of text: static data and JSP elements. Static data is simply text that is served up to the client without any processing. JSP elements are pieces of Java code that are executed on the server to generate dynamic content. The results of the execution are then sent back to the client as part of the response.

What are the types of servlet?

A servlet is a Java 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.

Servlets are most often used to process or store data submitted by HTML forms, but they can also be used to implement application logic not directly related to handling requests or generating responses.

There are two main types of servlets:

1) Generic servlets:
Generic servlets are servlets that implement the javax.servlet.Servlet interface. They are designed to handle requests from clients that cannot be handled by more specific servlets.

2) HTTP servlets:
HTTP servlets are servlets that implement the javax.servlet.http.HttpServlet interface. They are designed to handle requests from clients that use the HTTP protocol, such as web browsers.

What is difference between server and servlet?

A server is a computer program that provides a service to another computer programs (and its user). For example, a web server serves web pages to users browsing the internet. A file server serves files to computers on a network.

A servlet is a computer program that runs on a server and provides a service to clients. For example, a servlet might be used to process requests from a client program, such as a web browser, and generate a response, such as a web page.
