This post is about the very common problem of .Net and Java code interoperability. I met this problem at least twice, both times when a .Net application, which is already developed, was required to use some third-party Java API.

So let me introduce you the best solution I've ever seen: JNBridge. Here is a very nice presentation made especially for Microsoft Visual Studio team: JNBridge.wmv (6.78 mb)

Just a couple of slides from this presentation to let you realize the power of JNBridge:

The most impressive feature for me is the possibility to use .Net and Java code in one process via shared memory, however HTTP/SOAP connection is also a very useful option for distributed solutions.

JNBridge has a plugin for Visual Studio and Eclipse which allows you to effectively work with the tool in both IDEs.
