Overview The following sections describe the messages used for private request and response document exchange in TIBCO BusinessConnect EDI Protocol powered by Instream. You can use either TIBCO Rendezvous or JMS as the transport method for private process messages. The message-packet format varies with these two transport methods. With TIBCO Rendezvous, TIBCO BusinessConnect uses a subject name constructed as follows: prefix.installation.standardID.message_category.message_type For example: AX.BC.BC-ACME.X12.INITIATOR.REQUEST With JMS, TIBCO BusinessConnect uses a JMS queue for Initiator/Responder messages and a JMS topic for general messages. The topic name or queue name is constructed as follows: prefix.installation.message_category.message_type For example: AX.BC.BC-ACME.INITIATOR.REQUEST Topic and queue names do not include the standardID.
