The Siebel Enterprise Application Integration (EAI) framework provides transports that allow Siebel applications to exchange data with external applications. To do this, the Siebel EAI Dynamic Link Library (DLL) transport invokes the WebSphere Integration Adapter (WIA) Siebel connectivity DLL which invokes the access framework interface provided by the InterChange Server Express integration broker. The WebSphere Integration Adapter Suite consists of adapters for various applications, hence, InterChange Server Express and the appropriate WebSphere Business Integration Server Express Plus adapters can process the Siebel generated request sent by the DLL. The DLL is unidirectional; requests sent from Siebel to the broker (InterChange Server Express) are processed, and not vice versa.
