Requirements for Using the Service Protocol The Service protocol requires that the service or operation be invoked from the private process. Other requirements for using the protocol are as follows: • The invoked service will be one of the operations defined or created by the user. • The service does not invoke the MSH service, therefore there is no public transport invocation from TIBCO BusinessConnect. • No validation of the request or response schemas is performed by TIBCO BusinessConnect. The user implementing the interface or service is responsible to make sure that XML is sent from the private process and that the response sent by the implementer is valid. The Valid Email Addresses list is currently not used by the Service protocol.
