The ExpressAddIn is a developer tool that enables two-way communication between a third-party application and the IBM FileNet Application Integration infrastructure. The tool is implemented via COM interfaces and methods, and communication with the Application Integration framework is achieved through the use of an event sink and event handlers. The ExpressAddIn provides developers with a much simpler method for accessing the Application Integration framework than the objects in the Workplace Application Integration Toolkit and offers some features that are not available from the Toolkit, such as document tracking. In addition, the ExpressAddIn coalesces various Application Integration functionality into a single operation, whereas the Toolkit requires that the commands that correspond to that functionality be stacked in order to achieve the same behavior.
The ExpressAddIn is delivered with the Add-In sample application, which demonstrates how to use the ExpressAddIn to integrate a third-party application with the IBM FileNet Application Integration infrastructure. Developers can customize the sample code to rapidly integrate their application into the framework and easily customize an integration to meet their specific needs.
