Internet Services vs Web Services

[Former Member]

Ok

I couldn't find any relevant thread.

But what is the difference between a web (SOAP) and an internet service ?

Hi ,

Internet Services are available in SAP ITS which contain some GUI

so that they can called via browser / be displayed in portal .

Web Services dont have GUI , but they act like a Function which may take input parameters and may return output parametrs.

Typically Devlopers write the webservice and Publish it , so that others can consume the webservice in their application. The Web Service is referenced using its WSDL

which is in XML , this means you can write a webservice in any language and

consume it in other language as long as both the languages know how to work with XML.

If you have specific doubts , post back !

Cheers !

Hi Rajendra

Thanks for the reply.

Can we replace a web service with an internet service?

Ie could we expose an FM or a BAPI as an internet service?

And if yes should we do it?

What do we stand to lose by not using web services?

Hi Pushpraj,

All RFC Enabled BAPIs are callable as webservice from outside ABAP.

e.g from dotnet application.

Typically we use/expose TCodes as internet service

and use them in portal .

I did not get what you meant by saying

"could we expose an FM or a BAPI as an internet service"

Because these two are two completely different things !

if you explain what you are trying to achive then i will be in a better position to reply.

Are you Clear with the term internet service ?

Hi Rajendra

We lack the expertise on Web services but the user has worked on internet services.

So he wished to know if it was possible to use internet services instead of web ones like for exposing the FM HTTP_POST in a portal.

Also I developed a webservice on a server here and released it.

It generates a WSDL file too.

But when I try to execute it in WSADMIN, it gives IE error ( Page cannot be displayed ).

Does it require an Internet Connection?

And does the WSDL get updated if we change the attributes of the web service?

Thanks
