Hi

AS bhavesh said it's absoultely right.

it is simple a request coming from the internet to the XI server or may it may be sending a response from XI to the Internet.

coming to the use when ever u want to handle the data that is coming from a remote systems ie. through the internet we use webservice scenario i.e SOAP or HTTP scenarios.

Reward points if useful,

HI Keerthi,

In simpler terms, 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

hi,

from which system we actually invoke webservice?

Hi

Either use XI and call a webserivce -- XI acts as the Client here or,

expose an outboud message interface as a webserivice in XI so that another application triggers the call to XI and this application acts as the client.

Webservice can be at the sender side or the receiver side.

When at sender, XI will create the webservice as mentioned by the blog above and this webservice is invoked by the SOAP client at the sender end.

When at receiver, XI will invoke the webservice through the URL of the receiver webservice.
