Two Way Communication with JNI4NET - Call C# from JAVA then callback to JAVA from C#

[JA]

Okay, 

I am trying to make the most simple example in the work using JNI4NET but can't do it and need help. 

Here is the entire C# application:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using jnijavatestapp;


namespace JNICSharpTestApp
{
    public class JNICSharpTest
    {
        public void HelloWorldFromCSharp()
        {
            Console.WriteLine("Hi Java, this is C# talking!!!");
        }


        public void CallBackToJAVA()
        {
            JAVACLASS java = new JAVACLASS();
            java.HelloWorldJAVA();
        }
    }
}

Here is the entire JAVA application:

package jnijavatestapp;
import java.io.IOException;
import jnicsharptestapp.JNICSharpTest;
import net.sf.jni4net.Bridge;


public class JNIJavaTestApp
{


    public static void main(String[] args) throws IOException {
       InitJNI4Net();
       JNICSharpTest test = new JNICSharpTest();
       test.HelloWorldFromCSharp();
    }    
   
    public static void InitJNI4Net() throws IOException{
        Bridge.init();
        java.io.File file = new java.io.File("..\\COMMON_RESOURCES\\work\\JNICSharpTestApp.j4n.dll");
        Bridge.LoadAndRegisterAssemblyFrom(file);
    }
}

and another simple JAVA class:

package jnijavatestapp;


public class JAVACLASS
{
    public void HelloWorldJAVA()    
    {
        System.out.println("Hi C# this is JAVA Talking!!");
    }
}

All I want to be able to do is call the C# code from JAVA but ALSO CALL the JAVA code back from C#. Is this possible using JNI4NET? I want TWO WAY communication. But it seems that no matter what I do with the build order I can't get it to work. 

Here is what I'm doing: 

1.) Build C# Project

2.) Generate Proxies for C# app:

@echo off


cd COMMON_RESOURCES


echo.
echo Running ProxyGen.exe for C#...
..\JNI4NET\bin\proxygen.exe work\JNICSharpTestApp.dll -wd work


echo.
echo Building C#...
cd work
build

3.) Run build (called in above .bat)

4.) Generate JAVA Proxies:

@echo off
copy JNI4NET\lib\*.* COMMON_RESOURCES\work /y
copy JNIJavaTestApp\dist\JNIJavaTestApp.jar COMMON_RESOURCES\work /y


cd COMMON_RESOURCES


echo.
echo Running ProxyGen.exe for JAVA...
..\JNI4NET\bin\proxygen.exe ..\JNIJavaTestApp\dist\JNIJavaTestApp.jar -wd work


echo.
echo Building JAVA...
cd work
build

5.) Build again (called in above script also)

Messing around with above order I am able to call C# from JAVA but can never call JAVA from C# without it crashing. 

Can someone help!?!
