SCA inbound message flows
SCA inbound message flows are message flows that can be called by a service component running on WebSphere® Process Server. By using SCAInput and SCAReply nodes in your message flow, you can process messages from WebSphere Process Server.
When you want WebSphere Process Server to call services that are provided by WebSphere Message Broker, the SCAInput node acts as an SCA endpoint for the WebSphere Process Server service component. It accepts requests from WebSphere Process Server. The SCAReply node sends replies back to WebSphere Process Server.
- From a message set.
- From an SCA import component imported from WebSphere Integration Developer.
- Drag a Broker SCA definition with an extension of .insca from a message set onto the message flow editor canvas. If the .insca file contains only one-way operations, dragging a .insca file onto the canvas creates a SCAInput node. Otherwise, a pair of SCAInput and SCAReply nodes is created. If you use this method, many of the values for the properties of the node or nodes are supplied by the Broker SCA definition.
- Drag an instance of the node from the node palette onto the canvas. You then configure the node by dragging a Broker SCA definition with an extension of .insca onto the node.
The values for properties that relate to the binding supported by the specific SCA component are automatically supplied to the node from the Broker SCA definition; you do not have to manually provide them.
