WebService Creation

[Former Member]

Hi All,

I am having a scenario in which a webservice(already created for a webmethods<-->dotnet scenario) has to be recreated in XI.

So please advice me on how to recreate the WebService in XI referring to the Webmethods webservice.

If you say that we can create it through ID-->Define WebService then what Message Interface details are to be filled in the steps.

Thanks,

Abhishek.

HI,

You need to use Sender Outbound Message interface in ID-->Define WebService

Hi abhishek salvi ,

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.

The following websites give detail step-by-step solution for creation of webservice:

In XI/PI you can expose your outbound or inbound interface as a Webservice. As you said you need to create same service as it is available in Web methods.

Then from XI point of perspective you have to create Webservice to * scenarios and the outbound iterface will be expose as a webservice in XI that can be consume by the consumer.

Hi,

If you have the Webservice at Sender , then only we have to generate the Wsdl file through ID--Define Webservice, then will use SOAP Adapter here as sender.

If you are using the Webservice at receiver side means, dont require to generate the Wsdl file
