Procedure documentation Consuming a Web Service  Locate the document in its SAP Library structure

Use

To consume a Web service, you can create a deployable or a standalone proxy for the Web service in the SAP NetWeaver Developer Studio using a WSDL document as a basis.

The difference between a deployable and a standalone proxy is that, for a deployable proxy, the application of the Web service client must be deployed on the J2EE engine. A standalone proxy can be executed without the J2EE engine. For more information, refer to the section Deployable Versus Standalone Proxies.

The role of the Web service client developer has been created so that Web services can be consumed:

The Web service client developer has the task of integrating a Web service in an application. He or she knows the specific requirements for the Web service and creates the Web service client proxy definition. Afterwards, the developer programs the client application using the service endpoint interface.

 

Prerequisites

So that a suitable Web service can be found, the Web Service Framework provides the UDDI Client, a Web-based tool. Using this tool, you can search the UDDI directories. If the exact URL for the WSDL definition is known or available locally, this work step is omitted.
