Ted Neward talks about various ways Java and .NET can be used together focusing on examples of MS Office automation, and explains how various interop approaches (in-proc, messaging, web services) work and when to use them.
We learn how Java and .NET can interoperate with one another. We'll talk about how to leverage the strengths of each, such as using Microsoft Office to act as a rich client to a Java middle-tier service, or building a Windows Presentation Foundation GUI on top of Java POJOs, or even how to execute Java Enterprise/J2EE functionality from within a Windows Workflow host.
