Java under .NET

There is an interesting project - IKVM.NET - which includes JVM implementation in .NET. So, it is very easy both to run Java application under .NET (Mono) environment or to compile Java libraries and applications into .NET executables.

For example, in order to run Java application instead of using:

java -jar Application.jar

you have to use:

ikvm -jar Application.jar

To compile Java library into .NET DLL use:

ikvmc -target:library Library.jar

And finally, in order to convert your Java application into .NET executable, run:

ikvmc - target:exe Application.jar
