What do you think of this interoperability solution? Do you think it's fragile? Is it better or worse than rewriting code in the appropriate platform? Does Java/.NET interop simply exacerbate the problem that there are already too many different languages and technologies used within IT in organizations, or does it present a real-world solution? Let us know in the Java or .NET Technical discussion forums.
As the frequency of .NET and Java applications increases, we're headed for an interoperability imperative—we have to get both sides to work together. One way to do that is by adding an interoperability layer that gives .NET direct access to Java classes.

t's a fact that most production environments now use a mixture of both Java and .NET, despite all the partisan disputes over which side should "win." To be prudently responsible in the face of this business reality, it is imperative that developers get both sides to work together. Interoperability is no longer an option: fortunately, you do have some options for choosing the best path for achieving interoperability for your project.
Your specific interoperability needs may vary, based on your current systems and project specifications. Perhaps you already have some perfectly good "legacy" Java code that you don't need to change, but want to extend with new .NET components. Or, you're creating a new system, and want to assign tasks to the better-suited platform, so you're using J2EE's Enterprise Java Beans (EJBs) for the scalable back-end system, and .NET Windows Forms to create a rich desktop GUI. In either case, you may need direct access to Java classes from .NET. This article briefly discusses the major interoperability methods available and highlights some issues to consider as you make your interoperability selection, and demonstrate class-level interop with a specific example.
