Convert jar to dll

[pennaverde]

Hi, i post this message for ask just a little question. For those who don't know(I'm presented in the special section) I'm a producer of video games and I working with Java and C# in a program named Unity 3D. what I wonder is i need convert jar class to dll. I try to convert it by ikvm, and i try to follow
documentation but i get only errors. Can you show me how can i doing about the step.(sorry for my eng)
Thanks in advance :D

Your best bet is to use JNI or JNA to allow Java to communicate with a dll (if this is necessary).

can you be more detailed pls? thx a lot :)

Can you describe the functionality that the code in the jar file provides?
A jar file is is a container of .class files and other resources much the same as a zip file. The java command knows how to retrieve class files from jar files when it needs them for execution.
To execute a class file requires a JVM.

Actually, I was going to ask you the same. I assume that you want your jar to be in a dll to allow it communicate more easily with a C# program (but I'm just guessing since you don't say). Java Jars are not easily "put into a dll". Much easier would be to allow communication via sockets, or failing that creating a C bridge program and use JNI or JNA (easy to look up) to allow the C program to interact directly with Java.

I want to create a speech recognition app, and i want move the code of main class in new function(inside java), then(after converting the file in dll and import in c# prjct) call that function from c# code

this is the code hello world to edit
what do you think? it's possible?(obviusly i don't have change yet)

package edu.cmu.sphinx.demo.helloworld;

import edu.cmu.sphinx.frontend.util.Microphone;
import edu.cmu.sphinx.recognizer.Recognizer;
import edu.cmu.sphinx.result.Result;
import edu.cmu.sphinx.util.props.ConfigurationManager;

/**
 * A simple HelloWorld demo showing a simple speech application built using Sphinx-4. This application uses the Sphinx-4
 * endpointer, which automatically segments incoming audio into utterances and silences.
 */
public class HelloWorld {
	public static String whatTalk;
	public static Boolean isRecognize = false;
    public static void main(String[] args) {
    	
        ConfigurationManager cm;

        if (args.length > 0) {
            cm = new ConfigurationManager(args[0]);
        } else {
            cm = new ConfigurationManager(HelloWorld.class.getResource("helloworld.config.xml"));
        }

        Recognizer recognizer = (Recognizer) cm.lookup("recognizer");
        recognizer.allocate();

        // start the microphone or exit if the programm if this is not possible
        Microphone microphone = (Microphone) cm.lookup("microphone");
        if (!microphone.startRecording()) {
            System.out.println("Cannot start microphone.");
            recognizer.deallocate();
            System.exit(1);
        }

        System.out.println("Say: (fire ball | hello | hi | good bye | bye)");

        // loop the recognition until the programm exits.
        while (true) {
            System.out.println("Start speaking. Press Ctrl-C to quit.\n");

            Result result = recognizer.recognize();

            if (result != null) {
                String resultText = result.getBestFinalResultNoFiller();
                whatTalk = resultText;              //assign what i've talking at string var
                isRecognize = true;                  //tells the C # code that I'm talking
                System.out.println("You said: " + resultText + '\n');
                isRecognize = false;                 //end of tell
            } else {
                System.out.println("I can't hear what you said.\n");
            }
        }
    }
}
