Client/Server service
The Client/Server (C/S) service contains toolkit services that provide the client/server interface to be used by the operation infrastructure. It is composed of a client/server service on the client side (CSClient bean) and a client/server service on the server side (CSServer bean). The C/S service enables the following events:
Operations on the client side to invoke operations on the server side
Events to be sent from client to server and from server to client
Usually, on the client side, a unique CSClient instance is created that is in charge of establishing a session with the server side. However, if the client is connected to multiple servers, a CSClient instance is created for each of them.
In contrast, the C/S Service on the server side (CSServer) has a unique instance running on the server. It is responsible for waiting for incoming requests.
