Importing Web Services
Prerequisites
You have configured the Universal Description Discovery and Integration (UDDI) server. To do that, in the SAP NetWeave Developer Studio, choose Window → Preferences → Web Services → SAP Services Registry in the Server Name field enter name of the UDDI server.
When designing your composite applications with the Composite Application Framework (CAF), you can easily consume existing enterprise services, and map them to customizable application services that fit your particular needs. In addition, CAF allows you to edit the services in an entirely model-driven manner, which ensures flexibility, reusability, ease of development, and increased development productivity.You can browse the enterprise services that are offered in the Enterprise Service (ES) Workplace of the SAP Developer Network.
