Interoperability: Bridging .NET and Java

Introduction
Messaging
Web Services
Distributed Objects
Business Process Integration

In the heterogeneous world of enterprise computing, interoperability is no longer a luxury but a necessity. The multiple tier architecture of modern enterprises coupled with multiple development tools can lead to multiple headaches for developers. So what's a poor developer to do? Fortunately (some would say unfortunately), there are many ways to tackle this problem.

The resources I've assembled below should provide you with a broad overview of some of the techniques being used to bridge the worlds of .NET and Java technology. We'd love to hear about the interoperability issues you've encountered and how you went about solving them.
