Understanding iWay Business Services

iWay Explorer provides web developers with a simple, consistent mechanism for extending the capabilities of the iWay Application Adapter for SAP ERP. The iWay Business Services Provider (iBSP) exposes functionality as web services. It serves as a gateway to heterogeneous back-end applications and databases.

A web service is a self-contained, modularized function that you can publish and access across a network using open standards. It is the implementation of an interface by a component and is an executable entity. For the caller or sender, a web service can be considered as a black box that may require input and delivers a result. Web services integrate within an enterprise as well as across enterprises on any communication technology stack, whether asynchronous or synchronous, in any format.

After you browse the SAP ERP business object repository and create an XML schema for the object, you can generate an iWay Business Service for the object you wish to use with your adapter.

Important: The application target you use to create the web service will be the settings used to run the web service. This is particularly important in the case of settings for connection pooling and other usage parameters. If you are creating a production service, calculate the amount of users and the time each service execution takes when configuring connection pool parameters.
