I compiled it created the header file Using javah utility which gave me
GetFileAttributes.h file which has the following contents.

/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class GetFileAttributes */

#ifndef _Included_GetFileAttributes
#define _Included_GetFileAttributes
#ifdef __cplusplus
extern "C" {
#endif
/*
 * Class: GetFileAttributes

 */
JNIEXPORT void JNICALL Java_GetFileAttributes_fillAllAttributes
  (JNIEnv *, jobject, jobject, jstring);

#ifdef __cplusplus
}
#endif
#endif


then using this file i created a dll FillAttribImpl.dll
the following the source file dll.

after that when i executed the program it gave me the following error.

please help me solve this error . is there any problem int the program.
