I have one dll, I want to load that dll into java native interface but it was not working properly. so now i try to create new dll file and load existing dll into that new dll file and access method from existing dll . How Can i do this ??. Please help me.

Following code which i write in .c file

  #include "stdafx.h"

  #include <basetyps.h>

  #include <jni.h>

  #include "HelloPopup.h"

  #include <windows.h>

typedef int * (_stdcall * OPENCOM) (int ComPort);

HINSTANCE dllHandle;

int result;


* Class: HelloPopup

* Method: OpenSerialPort

* Signature: (I)I

*/`enter code here`

JNIEXPORT jint JNICALL Java_HelloPopup_OpenSerialPortDll

  (JNIEnv * env, jobject obj, jint ComPort)


  OPENCOM pOpenCom ;

  dllHandle=LoadLibrary ("AlzData.dll");

  POpenCom = (OPENCOM) GetProcAddress (dllHandle, "OpenSerialPort");

  int * ret = (* pOpenCom) (ComPort);


  FreeLibrary (dllHandle);

  return result;


.. but when i call the method in java native interface i was got an error..So this code i am little bit confused about this code it is correct or not please help me.
