Hi,

"Sentence:IMessage interface is for GCP messages.

"

IMessage is specialised version of ICMIMessage

The Enterprise Services Framework (ESF) Generic Client Proxy (GCP) is used to connect to the Object Access Layer (OAL) from Web Dynpro. The GCP provides an interface based on the ESF definition through which a pattern can connect to any backend. Backend connectivity to data and metadata is through ESF.

The OAL implementation of ESF GCP has the following subtasks:

● Access to the metadata repository and provision of metadata information to Web Dynpro via data model information.

● Caching of data

● Connection to cross application (xApps) EJBs (Enterprise Java Beans)

● Generic service module implementation

● Service facade to instantiate OAL implementation

Hi Gurram,

GCP is Generic Client Proxy.

The Generic Client Proxy is the upper-most layer of the ESF client framework. The task of the Generic Client Proxy (or GCP for short) is to provide ESF clients access to the ESF framework and so to the backend data, that is accessible in the corresponding backend.
