What is web service – javatpoint

A Web Service is can be defined by following ways:

  • It is a client-server application or application component for communication.
  • The method of communication between two devices over the network.
  • It is a software system for the interoperable machine to machine communication.
  • It is a collection of standards or protocols for exchanging information between two devices or application.

Let’s understand it by the figure given below:

As you can see in the figure, Java, .net, and PHP applications can communicate with other applications through web service over the network. For example, the Java application can interact with Java, .Net, and PHP applications. So web service is a language independent way of communication.

Types of Web Services

What Is The Difference Between Web Services and APIs?

Web services and APIs are two of those overlapping tech terms that regularly get confused. You might have even heard these words used interchangeably, but are they even the same thing?

While they do have some overlap, web services and APIs are two different concepts. If you need a quick and simple explanation, we’ve got you covered. In previous articles, we broke down the difference between microservices and APIs, SDKs and APIs, and today we’ll do the same for web services and APIs!

Note: There is some disagreement among developers on what exactly defines a web service or API, and how the two differ. We’ve done our best to stick to the facts, but bear in mind that everyone has their take on precisely what these concepts refer to.

What Is an API?

The term “API” stands for Application Programming Interface. If you break that down word by

What Are Web Services and Where Are They Used?

by Segue Technologies
on March 18, 2013

Web Services are the means by which devices communicate over the World Wide Web. Whether you use a mobile application, search engine or an enterprise system, the user piece of the application (the interface) resides on your device. The data, and potentially the business rules, live on some other server on the network. How your interface communicates with the server piece is the role of Web Services.

The official definition of a Web Service is “a software system designed to support interoperable machine-to-machine interaction over a network.” Breaking this down, the communication between servers requires an agreed-to (i.e., interoperable) format and structure: I need to understand what you want, and you need to understand what I send you.


For most systems, these specifications are defined in the system’s Web Service Description Language, or WSDL. A WSDL defines how incoming information, such

Shenzhen SEG Electronics Market: The Complete Guide

The cheap prices of electronics in Shenzhen have been attracting penny-pinching Hong Kongers for years but now tourists, unimpressed by the small savings on electronics available in Hong Kong, have started venturing north of the border to take advantage of the cheaper price tags. For the best selection, head straight to the massive, and at times overwhelming, SEG Electronics Market.

About SEG Market

Reckoned by some to be the biggest market of its kind on the globe, this is a supersized version of Hong Kong’s many computer markets. The SEG Electronics Market is officially on the first ten floors of SEG Plaza, named for the Shenzhen Electronics Group. However, SEG Electronics Market and SEG Market are also used to reference the area surrounding the Plaza building. It’s impossible to accurately estimate the number of sellers but it is certainly in the high hundreds. The fact that stalls are run as

Web Services Explained

First, Web Services using SOAP, REST, and JSON are discussed. This is followed by a history of Web Services covering the Web Services Description Language (WSDL) and Universal Description, Discovery, and Integration (UDDI).

Web Services Specifications

Three specifications for Web Services are illustrated in this section: SOAP, REST, and JSON.


SOAP was originally part of the specification that included the Web Services Description Language (WSDL) and Universal Description, Discovery, and Integration (UDDI). It is used now without WSDL and UDDI. Instead of the discovery process described in the History of the Web Services Specification section below, SOAP messages are hard-coded or genereated without the use of a repository. The interaction is illustrated in the figure below. More on SOAP.

Representation State Transfer (REST)

Representation State Transfer (REST) appeals to developers because it has a simpler style that makes it easier to use than SOAP. It also less verbose so
