13 Online Courses for All Levels to Learn Web Service

In this article, you can find Web Service online courses for all levels.

The term “Web service” describes a standardized way of integrating Web-based applications using the XML, SOAP, WSDL and UDDI open standards over an Internet Protocol backbone. XML is the data format used to contain the data and provide metadata around it, SOAP is used to transfer the data, WSDL is used for describing the services available and UDDI lists what services are available.

Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always-on as in the concept of utility computing.

Many organizations use multiple software systems for management. Different software systems often need to exchange data with each other, and a Web service is a method of communication that allows two software systems to exchange this data over the Internet. The software system that requests data is called a service requester, whereas the software system that would process the request and provide the data is called a service provider.

Different software may use different programming languages, and hence there is a need for a method of data exchange that doesn’t depend upon a particular programming language. Most types of software can, however, interpret XML tags. Thus, Web services can use XML files for data exchange.

In a Web service a Web technology such as HTTP is used for transferring machine-readable file formats such as XML and JSON.

In practice, a web service commonly provides an object-oriented Web-based interface to a database server, utilized for example by another Web server, or by a mobile app, that provides a user interface to the end-user. Many organizations that provide data in formatted HTML pages will also provide that data on their server as XML or JSON, often through a Web service to allow syndication, for example, Wikipedia’s Export. Another application offered to the end-user may be a mashup, where a Web server consumes several Web services at different machines and compiles the content into one user interface.

Develop RESTful Java Web Services using JAX-RS and Jersey
Vinod Kumar Kayartaya via Udemy
JAX–RS the Java API for RESTful Web Services is a Java programming language API specification that provides support in creating web services according to the Representational State Transfer (REST) architectural pattern. JAX–RS uses annotations, introduced in Java SE 5, to simplify the development and deployment of web service clients and endpoints. From version 1.1 on, JAX–RS is an official part of Java EE 6. A notable feature of being an official part of Java EE is that no configuration is necessary to start using JAX–RS. For non–Java EE 6 environments a small entry in the web.xml deployment descriptor is required. This course will guide you through the steps in creating powerful RESTful web services using the Java official API.
