Dear Friends,
I like to know what is meant by webservices and <b>exact usage of Webservices</b>..
Kindly show me some blogs related to Webservices.
Hi,
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 <b>WEBSERVICE,SOAP</b> nicely
for that check these post

Hi Karthik,
Which aplication do you want to expose as a webservice?
In XI you have an option of generating a WSDL for a message interface. You can use this WSDL to make a web service call from other applications. This WSDL can be generated in the integration directory. To know more on this refer the the How to guide on SOAP adapters on SDN.
You could also do this to your EJB's from NWDS. In the e-learning section on SDN you have presentation on Webservices. Refer it to give you an idea as to how to expose your applications as web services.

Chandra
Hi Karthik,
We have already given u ample no. of blogs...just check our posts correctly....

Exposing BAPI as Web Services through SAP XI

<b>**Please close the thread if u have got ur answer</b>
Hi
A Web service is any interface that is described and can be called through the Web services standards. The standards stack is continuously growing, with some standards, such as SOAP and WSDL, being widely accepted and supported while others still are merely proposals and neither accepted nor supported by the industry as a whole.
Take an example
A SAP Web Dynpro client sends a Web service request to SAP XI. The request performs
a credit limit check and contains the amount as one of the input parameters. Based on a
routing rule in SAP XI, the Web service request is directed to an SAP R/3 system (for
small amounts) or to a .NET application (for larger amounts).
Coming to creating Web Services
You can expose any RFC xxx as a web service
In SE37
In order to start the Web Service Creation Wizard, please click on the top navigation bar on Utilities(M)>>MoreUtilities>>Create Web Service>>From the Function Module.
The wizard will open, click Continue and choose your RFC
Thanks
