I've started using IKVM to translate Java libs into .NET CIL. I can successfully write a C# program that pulls in (inproc) a translated Java assembly as a reference and make calls to the translated Java code.
My question is, is anyone familiar w/ how to make calls (callbacks) from Java to C# using IKVM? I've been looking for a good tutorial or explanation but haven't seen one yet.
Any help is appreciated. Thanks,

Ladies and Gentlemen, I figured out my own question. Code first followed by steps.
Java Class
public class TestClass {
private cli.CSharpLibrary.Library m_lib = null;
public void AddDelegate( cli.CSharpLibrary.Library lib )
{
m_lib = lib;
}
public void FireDelegate()
{
if( m_lib != null )
{
m_lib.ExecuteRunnableDelegate();
}
}
public void PrintInt()
{
System.out.print(23);
}
}
C# Class
using ikvm.runtime;
using CSharpLibrary;
namespace CSharp
{
class Program
{
public static void DelegateTarget()
{
Console.WriteLine("DelegateTarget Executed!");
}
static void Main(string[] args)
{
Library lib = new Library();
lib.m_runnableDelegate = new Delegates.RunnableDelegate(DelegateTarget);
TestClass tc = new TestClass();
tc.AddDelegate(lib);
tc.FireDelegate();
}
}
}
1) Write your Java app
2) Convert your *.class files into a jar file (jar -cf myjar.jar *.class)
3) Convert the jar file into a .NET assembly (ikvmc -reference:csharpassembly.dll myjar.jar)
Should work at this point. You can run your C# program, have it call the converted Java program and vice versa. Watch out for the "-reference" flag on the ikvmc call. This tells IKVM when it's converting the Java code that csharpassembly.dll has some class definitions that it needs to watch out for.
