Hi Satya

Web Application is very simply u can say the application which can run on Web.In other way the application which supports http protocol and can be accessed across geography.

Webservice is also a web application which specialized architecture in which application can communication over web irrespective of the underlying technology they have built upon, but they must support XML.

Suppose an application built in Microsoft technology can communication with application built in Java/J2EE tech.

Suppose a method add(first_name,last_name) is coded in .NET which can be published as a webservcie which transform this method in to XML format(WSDL) on the net call webservice provider. Then Java application can access this method add() by accessing that XML structure from the provider.

Hi satya kumar ,

Web service

A Web service is a self-contained, modularized functionality, which can be published, discovered, and accessed across a network using open standards and which is supported by SAP NetWeaver. Web services cover services provision for integration within an enterprise as well as cross enterprises on top of any communication technology stack, whether asynchronous or synchronous, in any format.

Web Services in the NetWeaver framework play an important role in facilitating the integration of disparate applications from various departments or trading partners and thus increasing business productivity. This benefit allows small and medium businesses also to integrate their business applications with larger trading partners. The benefit derived from this seamless integration introduces security concerns when all the business logic is now being exposed through a standard interface that is a catalyst for security vulnerabilities. SAP Security Managers must use automated diagnostics tools to ensure that the security vulnerabilities are caught in pre-production and in post-production phase.

Hi satya,

1)About webservice?

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.

and for web application see the below link

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.

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.
