Recently, some users have reported that they have encountered the java Servlet API.
which contains many interfaces and classes that can be used by a servlet or a web basket. They are not specific diets for. Javax. Servlet. The http package contains user interfaces and classes responsible for HTTP requests only.
Setting up servlets
A servlet is a small Java program that runs on a web server. servlets and receive responses to requests, including clients, The Internet is usually HTTP, via the Hypertext Transfer Protocol.
Is servlet REST API?
Servlets are a RESTful API, but they are not. Servlets can run mostly in a servlet container, but RESTful services can also run in an engine container. RESTful talks about resources/entities/verbs and gives them more concrete ways to end up using services, i.e. Is there a transparent explanation for the use of Spanish HTTP verbs.
For to implement this implementation program, you can write a generic matrix usually a lengthened servlet javax.servlet.Genericservlet
or Http-servlet das provides javax.servlet.http.HttpServlet
.
This interface defines initialization methods to serve a servlet, delete requests, as well as a servlet on all servers. They are known as lifecycle methods and are also mentioned in order: next
- The created servlet is then initialized with the
init
method.service
method.destroy
method, then garbage collection and finalization. This interface is in addition to lifecycle methods. Provides one of the getServletConfig
methods that retrieves the servlet definitely uses i for getting information and facts about starting and getServletInfo
Which method allows a servlet to return basic information about itself, such as author, version, and copyright.
The javax.servlet but javax.servlet.http packages represent servlet-based interfaces and API classes.
The javax.servlet package contains various interface classes used by the Gold servlet web container. In fact, they do not depend on the protocol.
The javax.servlet.http shorthand package contains interfaces and compatible classes, with HTTP requests only.
Interfaces In Javax.servlet Are Packages

Interface Missing From Package Javax.servlet.http
Is Java Servlet an API?
You must use the servlet API, which is designed for servlets. There are two packages to keep in mind when using the API, usually javax. A servlet package containing courses on supporting generic (independent) servletfrom the Servlet Protocol) and then javax.
The Javax.servlet.http program has many interfaces. Are they the following:
- HttpServletRequest
- HttpServletReply
- HTTP session
- HttpSession Listener
- HttpSessionAttribute listener
- HttpSessionBinding Listener
- HttpSessionActivationListener
- HttpSessionContext class (deprecated)
Javax.servlet.http Package

To create servlets, the Servlet needs to use the API. There are two things to keep in mind when using the API:javax.servlet
containing a course on general support (protocol-independent du, servlets), but package javax.servlet .http
java.lang.Object|_extended javax.servlet.GenericServlet |_extended javax.servlet.http.httpservlet servlet
Everyone must implement this java.servlet.Servlet
interface, you can do this by extending one of the following two javax options: .servlet.GenericServlet
or javax .servlet.http.HttpServlet
. The former is often used for protocol independent servlets, while the latter is Http specifically for Servlet.Servlet
Like
Generic I, As Described Above, When Creating A Generic Servlet, You Must Extend The javax.servlet.GenericServlet
State. The GenericServlet Framework Has An Abstract Service(). Means That A Subclass Of GenericServlet Should Always Override A Method In Service() Anyway.
Signature Pointing To The Abstract Service() Method:
public Void Service(ServletRequest, ServletResponse) ServletException, Throws Java.io.IOException
What is javax servlet service?
The Service() Method Includes Arguments: Two ct ServletRequest And The Concept Of ServletResponse. The Request Object Tells The Servlet The Request Made By The Client, While My Response Object Is Used To Return Any Client Response Von Art To .Servlet
If
http In a servlet making public http, you need to extend javax.servlet.http.Httpservlet
, class, which is an abstract class. Unlike the generic servlet, the HTTP servlet has no method to bypass service(). Instead, one or more of the following methods are overridden. It must replace at least one method from the following list:
In an HTTP servlet, there is no need to bypass the service() method, since the parameter sends HTTP requests to the correct system handler. For example, when it receives an HTTP GET request, it sends the main request to the doGet() method.

The servlet-api JAR file is a set that contains the interfaces and classes from the Servlet API specification. The servlet-api bottle only contains the interface (API) associated with the servlet specification, so you can use it to develop your web application.
