How to call Java code from C#?

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 ?

There are so many options,

  1. sockets

  2. web services

  3. Message bus

  4. Use a/any database! (sorry if sound silly)

Here's a discussion which may be handy: https://gridwizard.wordpress.com/2015/01/14/java-and-dotnet-interop

Really depends on what you're building!

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.

alternatively you could write a webservice/xmlrpc layer between the two.

I seem to remember that there is a tool calles grassshopper that will compile your .Net code into JVM bytecode.

I've also heard good things about IKVM

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.
