Hi Krishna ,

These r the details regarding Web services :

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 Krishna

> a) What is webservices and what is the significance of it?

A Webservice is an application over internet. This application is able to process request and provide response also. Usually the web service created is linked internal with the corporate landscape to analyze the data.

more one webservice

http://en.wikipedia.org/wiki/Webservice

> b) How to develop and post webservices over internet?

It can be developed using web service development too, even we can use eclipse, NW developer studio and later these services need to be published over internet for usage

http://www.sitepoint.com/article/own-web-service-php-xml-rpc

> c) How to use existing webservices?

We can use the existing webservices using the url of the webservice

regards

[prateek]

a) Usually any service or any functionality exposed on internet is a webservice.

b) A webservice can be developed in many ways.. e.g. in .Net, in Java.. u have to deply it on some Web server.

Web service can be exposed on internet using UDDI.

c) Existing web services can be aaccessed using the uRL of these webservices

Hello Krishna,

WebService is an application on the Web/Internet. Wheneever Service is requested by the user, it provides the service (i.e Request/Response)

A web service is a collection of protocols and standards used for exchanging data between applications or systems

In SAP world, we can expose an application into the Webservice. For e.g We can expose ABAP programs into Webservice.

It is basically an XML code. If you want to use an application software (ex:a calculator/language translator) which is present on another server, say you want to calculate ab and show it on your browser for example. So, you write an XML code which will send the request to the application-> you send the parameters a, b and the operator ''. You will get back the response as the result of the operation(say 'c'). Hence, with the help of a webservice, you avoid writing the code to calculate a+b=c. More about webservices is here:-http://www.w3schools.com/webservices/default.asp

U need to understand WEBSERVICE,SOAP nicely

for that check these post

Hi,

Can you please send me your email

____

<b>Please do not request email IDs,</b>

i.e.,

<a href="https://www.sdn.sap.com/irj/sdn/wiki?path=/display/home/rulesofEngagement&">Rules of Engagement</a>

____

add I will send u the documents on the same.

2) Normally we need to get the std wsdl from the webserver and import it into the external definition. OR we need to define the web service for the interface in the configuration and create a WSDL and once that is created we need to import it into the External definition.

Thanks and Regards,

Chitag Gohil
