Using JNA to access export native classes

Hi everyone,

Currently I am working on java project which uses methods and classes present inside a DLL. Suppose I have such a method inside the DLL(named MyDLL.dll):

Quote:

---

Method inside my DLL code

---

Code :

---

extern "C" __declspec(dllexport) int myMethod();

---

Quote:

---

corresponding JNA implementation

---

Code :

---

import com.sun.jna.Library;
import com.sun.jna.Native;
import com.sun.jna.Platform;
 
/** Simple example of native library declaration and usage. */
public class HelloWorld {
    public interface CLibrary extends Library {
        CLibrary INSTANCE = (CLibrary) Native.loadLibrary("MyDLL", CLibrary.class);
        int myMethod();
    }
 
public static void main(String[] args) {
String libPath = "path to MyDLL.dll";
System.setProperty("jna.library.path", libPath);
int RetVar = CLibrary.INSTANCE.myMethod();
}          ////main function ends
 
}                ////class ends

---

So, my doubt is that like the function present inside the DLL, I have also got a class inside the DLL which needs to be exported:

Quote:

---

Class inside my DLL code

---

Code :

---

extern "C" __declspec(dllexport) Class myClass
{
//////code inside class
};

---

So, now the question is how I am gonna use this native class inside my java code like i did for the native method?:confused:

Thanking in advance,

Hello everybody,

Someone, please reply to this query. It's kinda urgent. Sorry, for the urgency, but atleast tell if it is possible or not? I am using JNA(Java Native Access) package for accessing native methods. Is it possible by the use of any other package like JNI or some other package?

Waiting for a reply,

With regards,
Satya Prakash.
