![]() Specifying the name of the service, the service binding type, and other information. Figure A-3 describes the service registration process. After pipeline actions are executed, the outbound endpoint is closed.ĭuring service registration, a wizard guides you through a number of Oracle Service Bus Console pages. Eventually the transport manager invokes the response pipeline. When a response comes in, the transport provider calls the TransportSendListener object. ![]() For example, for a JMS message, the transport provider uses the JMS API to populate the headers and the payload and calls the protocol-specific send operation. The transport provider then asks about the metadata and payload and other information and takes appropriate action. The transport provider creates an OutboundTransportMessageContext. TransportManager calls the transport provider to send the message. Next, the provider calls TransportManager (the central hub for the transport subsystem) to send the message asynchronously. The transport provider creates metadata for the request and creates a TransportSender object, which includes information about the payload and quality of service and retry information. The Oracle Service Bus runtime routes the message to an external service. The sequence diagram shown in Figure A-2 describes the flow of outbound messages through Oracle Service Bus runtime. The response is sent back to the client.Ī.2 Oracle Service Bus Runtime Outbound Messages The runtime asks the MessageContext to create the response metadata and the response payload, and then calls close(). It also asks about the metadata and payload, which are required for processing. The Oracle Service Bus runtime asks for the message context's service, service version, and other information. The transport manager preprocesses the message and passes the message to the Oracle Service Bus runtime for processing. The transport provider calls the transport manager to receive the message. The message context packages headers from the request into a metadata object, converting the payload from an HTTP stream into a specific Oracle Service Bus source object. The transport provider creates a data structure called InboundTransportMessageContext. The sequence diagram in Figure A-1 describes the flow of inbound messages through Oracle Service Bus runtime.įirst, an inbound artifact, such as an HTTP Servlet, intercepts a client request.
