used with connectors, with the Server Access Interface, or with both. Solutions can be implemented for applications distributed on a network, and depending on the requirements and components available, for applications that reside across the Internet. Integration on a network In this example, the goal is to automatically update an enterprise resource planning (ERP) application when customer information changes in a customer interaction management (CIM) application that resides on the same network. The IBM WebSphere Business Integration Server Express solution might consist of the hypothetical CustomerSync collaboration, connectors for the CIM application and the ERP application, and definitions of business objects that represent customer information. Figure 1 illustrates that solution. CustomerSync Collaboration CIM Connector ERP Connector CIM Application ERP Application Customer data Customer Business Object Figure 1. CIM-to-ERP Customer Data solution Connectivity over the Internet Data exchange across the Internet can be implemented using the Server Access Interface and certain technology adapters. In this approach, the Server Access Interface is used to pass synchronous calls into the IBM WebSphere Business Integration Server Express; connectors that use Internet technology standards are used to send data from the IBM WebSphere Business Integration Server Express: v Calls from external browsers (or other sources over the Internet) can be received by a web servlet that sends the calls through the Server Access Interface to trigger business processes in collaborations. v On behalf of collaborations, connectors for specific Internet technology standards (such as XML) engage in request/response interactions with external destinations that understand the specific data format. The Server Access Interface resides at a hub site on the InterChange Server Express (ICS). When the Server Access Interface receives a call, it sends the data to a handler for that specific data format (such as the XML data handler). The data handler transforms the data into a generic business object. The Server Access Interface then sends the business object to a collaboration. The collaboration Chapter 1.
