Service to send an electronic offer upon a previously received CLOfferRequest. Usually to be used by a Server. The function allows the sending of a "transparent" data string via SEMPER to a SEMPER server and the corresponding B-application. The data itself, that means the format and structure are defined by the BA (e.g. EDIFACT Offer. Before the offer send method is called an object of the class CLConnection has to be created to establish the connection to the remote SEMPER system. If a correct CL connection is established, the offer serivce can be used. The offer method creates for the passed data the corresponding container structure within the transfer layer and sends it to the remote system.
Parameters:
connection - object representing the connection to be used to send data to the remote host.
ba_description - very short informal description of the BA
data - reference to a object containing all data for the offer.
satt - reference to an object containing all relevant security attributes for sending the offer.
Returns:
returns status of send transactions
Throws: CLException
A serious error occured during attempts to send a container.
