0 likes717 views
The document discusses leveraging Oracle9iAS Web Services for integrating e-business applications. It outlines exposing existing E-Business Suite APIs, workflows, and XML transactions as Web Services. It also describes invoking Web Services from within workflows and in response to business events using the Integration Gateway and its client API. The Integration Gateway acts as a central hub that manages access to external interfaces and provides out-of-the-box integration capabilities.
