Diff Between Web Service And Web Application

Satya,

Web service is a XI iterpretation or mirror image to WEB application.

Although there is hardly any configuration for web service in XI.

To a great extent, communication between B2B and e-Commerce applications is based on manually declared interfaces, message formats, and arrangements between business partners. Using Web services, this process can be simplified. Web services are Web-based interfaces that can be integrated into business scenarios of a company based on open and commonly accepted standards. Using Web services enables you to combine functions implemented on different software components into a single process.

Web services are self-contained, modularized, executable entities that can be published, searched for, and accessed across a network. For a caller or sender, a Web service is a black box that may require input and delivers a result.

Features

The SAP Web Application Server allows companies to extend their solutions by exposing and integrating Web services. The SAP NetWeaver Developer Studio provides an environment for publishing, discovering, and accessing Web services. Therefore, it allows the SAP Web Application Server to act both as a “server” and as a “client” for Web services.

The Java Web Service Infrastructure allows developers to:

· Display all self-contained, modularized functions implemented as Enterprise Java Bean (session bean) or as a Java class in a Web service. This includes functions provided by SAP as part of mySAP solutions or developed by the customer or partner. The Web service can be used across the Internet through standard protocols and can easily be integrated in any development framework. Displaying a Java class as a Web service is also possible.

· Integrate Web services, irrespective of where they reside or how they are implemented. Therefore, business processes spanning different systems, both intra-company and cross-company, can be implemented.
