The SAP Business Connector (SBC) is a great tool for XML-enabling ABAP-based SAP components like R/3. It uses a service-based architecture and delivers many ready-to-use services. Customers can also easily build services — either flow services using SBC’s graphical design environment or Java services by writing Java code. While much can be accomplished with both, Java services offer distinct advantages in some areas, including performance, exception handling, and support for a range of data types and operations. This article shows you how to create a Java service from scratch or by using existing Java libraries, and how to leverage the ability of Java and flow services to invoke one another by looking at an example flow service that invokes two Java services.
