Designing Services in CAF Core
Purpose
With this component of the CAF Core Developer’s Guide, you will get involved in designing services with the Composite Application Services (CAS) perspective of SAP NetWeaver Developer Studio. This includes not only creating and modeling entity, application, and external service types, but generating these services and setting framework events for use in your CAF Core application.
Features
In this section, you will be introduced to the following:
You will find an overview of the different types of tab pages associated with entity, application, or external services.
You will learn how to create and model services with the Composite Application Services modeling tool of NWDS. You will also learn about encapsulating RFCs and WS in CAF Core and learn about transaction support.
You will learn the specifics of operation mapping in the CAF Core design time. It offers you rules and guidelines for preparing your services for integration in the framework.
You will learn how to use CAF authorizations to protect the access to application and entity services you have created.
● Service Eventing and Notifications
You will learn about the environment for sending framework events from entity services via generic Java Messaging Services (JMS) and get an overview about the notification and subscription process in CAF.
Constraints
In this section of the SAP NetWeaver CAF Core Developer’s Guide, you will neither be reintroduced to the CAS plug-in to SAP NetWeaver Developer Studio nor to the types of services and their functions in creating projects in CAS. For this information, first read Working with Composite Application Services under Getting Involved.
