How to call Java code from C#?

Question

We've developed a Java application and would like to use this application from a C# client. The application has dependencies on Spring, Log4j, ...

What would be the most efficient mechanism - make DLL(s) from Java code, ... - to achieve this ?

Answer 1

IKVM!

It is really awesome. The only problem is that it DOES add ~30MB to the project. log4net and Spring .NET are available as well, but if living with existing code, go the ikvm route.

Answer 2

I am author of jni4net, open source interprocess bridge between JVM and CLR. It's build on top of JNI and PInvoke. No C/C++ code needed. I hope it will help you.
