Front-end to our Java-based server is written on C#/.NET. Interoperability is achieved using XML/WS-based server API (as well as some custom binary format for high volume data responses). Typical architecture. Well, this is going to change now, after we discovered IKVM project. IKVM translates Java byte code into MSIL.
The lack of Microsoft Java implementation for .NET platform has obvious commercial reason. But what cannot be done by the largest software company was done by single developer - Jeroen Frijters (the man behind IKVM). Amazing.
