Transport Methods
The method on a transport adapter's business service controls the action to be performed by the transport. There are two outbound methods and three inbound methods available for EAI Transports. Not every method is available on every transport.
For each method, there are a number of common parameters, as shown on Table 4, as well as transport-specific parameters that are discussed in the respective chapter for each transport.
Outbound Methods
Available outbound methods depend on the transport business service in use, such as EAI MQSeries AMI Transport or EAI MSMQ Transport. The business service sends messages from the Siebel application using the appropriate communications protocol, such as MQSeries, MSMQ, HTTP, and so on. There are two outbound methods that you use to send requests from a Siebel application to another application:
- Send. Sends a message from a Siebel application when the Siebel application does not need a response. This is an asynchronous (with the exception of the EAI HTTP Transport which expects a correct HTTP response) request method, because the Siebel application does not need to wait for a response before continuing with the process.
- Send and Receive. Sends a message from the Siebel application when the Siebel application needs to receive a response before continuing. This is a synchronous request and response method, because it requires a response before the Siebel application can continue.
Inbound Methods
Available inbound methods depend on the transport business service in use, such as EAI MQSeries AMI Transport or EAI MSMQ Transport. The inbound methods monitor a specified queue and upon receipt of a message, dispatch it to another service.
There are three inbound methods that can be used to receive requests from another application:
NOTE: There are server components (called receivers) on top of the inbound methods that run as Siebel Server tasks. When running an EAI receiver such as the SAP IDOC Receiver, MQSeries Server, MQSeries AMI Receiver, or MSMQ Receiver—using the methods ReceiveDispatch or ReceiveDispatchSend—if the dispatch service has an error, the receiver shuts down. Check the Status column on the Component Tasks for details about the cause of the error.
