Express Plus, you may wish to consider obtaining additional, application-specific connectors that are included in an Adapter Capacity Pack. Capacity packs are separately available as optional additions to IBM WebSphere Business Integration Server Express Plus. For more information about the connectors supplied with the product and the connectors contained in Adapter Capacity Packs, see the IBM WebSphere Business Integration Server Express Installation Guide. You do not do any customization on connectors themselves, but you may need to make modifications to some of the integration components with which the connectors interact. And you will need to configure the connectors. These tasks are described in the topics that follow. Develop or modify application-specific business objects After you have selected and installed the files for your connector, you should develop the application-specific business objects for it. This topic provides a brief overview of that task. For details about working with application-specific business object definitions, see the Business Object Development Guide. You should develop application-specific business objects after connectors, because you must understand the connector in order to develop business objects for it. You should develop application-specific business objects before you develop generic business objects, because generic business objects generally represent a superset of the application-specific business objects in an interface. Many adapters include object discovery agents (ODAs) to assist you in generating application-specific business objects that work with the connector. Refer to the guide for the adapter to determine if the adapter features an Object Discovery Agent (ODA) that can be used to generate application-specific business objects. ODAs can greatly expedite this stage of development. You may also need to design and create application-specific business objects individually. It is recommended that you create application-specific business objects in multiple iterations. Develop the application-specific business object at first as a relatively simple structure and then test it to make sure that the connector can use the business object structure to exchange data with the application successfully. Then add a layer of complexity and re-test the business object to make sure that the interface still works in spite of the modifications. Repeat this process until the application-specific business object is as large and complex as it has to be to satisfy the interface. When you create the business object definition you should also create any source application triggers or other event detection mechanisms if necessary. For details about designing and developing application-specific business object definitions, see the Business Object Development Guide. Configure connectors When you configure a connector for the purpose of unit testing an application-specific business object you may not yet have developed all of the business object definitions and maps that the connector requires to perform its role in the implementation. You can, however, add support for the business object definition you need to test and be able to test it successfully without those other components. When you have finished developing the other components you must 30 IBM WebSphere Business Integration Server Express and Express Plus: System Implementation Guide
