3 External System Simulation
This section describes how simulation of external system will happen with OBAPI considering external system exposing JMS.
This simulator will consume request and produce response. It will pick up request from producer queue and post the response on consumer queue. For same, ExtxfaceSimulatorMDB.ear should be deployed, as Enterprise Application, on application server. MDB listener in ExtxfaceSimulatorMDB.ear will listen producer queue, retrieves request whenever it comes, process it and sends response to the consumer queue. Below sequence diagram explain the same.
