Methods

 o send
  public int send(CLConnection connection,
                  String ba_description,
                  CLContentData data,
                  Security sattr) throws CLException
Method to send an electronic offer-request. Used by Clients. 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 connection is established, the offer request service can be used. The offer request method creates the corresponding container structure within the transfer layer and sends it to the remote system. Before sending the data, this information will be displayed on the TINGUIN window.
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 - references to an object containing all data for the offer-request.
sattr - references to an object containing all relevant security attributes for the offer-request.
Returns:
returns status of send transactions
Throws: CLException
A serious error occured during the attempt to send a container.
Overrides:
send in class CLServices
