Part one offers a quick introduction to the J2EE (WebSphere) and .NET technologies. It also depicts a basic architectural model that can be used to represent both WebSphere applications and .NET applications.

Part two identifies several potential technical scenarios for coexistence via point-to-point integration between applications deployed in the IBM WebSphere Application Server and applications deployed in the Microsoft .NET Framework. This part provides in-depth technical details on how to implement certain scenarios using today's existing technologies.

Part three, provides general guidelines for solution developers. A list of supporting technologies can help with the solution implementation. The Quality of Service chapter is a collection of services available on both platforms.

The appendixes go further by using other IBM technologies and describing two integration solutions between Lotus Domino and .NET applications.
