JNI gesucht

[Luckie]

Ich habe jetzt folgendes Java Programm:

Code:

public class HelloWorld {
    public static void main(String[] argv) throws Exception
    {
       HelloWorld test = new HelloWorld();
       int res = test.Test();
       
       System.in.read();
       
       System.out.print(res);
    }
    
    public int Test()
    {
       System.out.print("Hello, world\n");
       return 42;
    }
}

Dazu das C-Programm:

Code:

#include <stdio.h>
#include "jni.h"

int main()
{
   JavaVMOption options[1];
   JNIEnv *env;
   JavaVM *jvm;
   JDK1_1InitArgs vm_args;
   long status;
   jclass cls;
   jmethodID mid;
   jint square;
   jboolean not;

   options[0].optionString="-Djava.class.path=.";
   memset(&vm_args, 0, sizeof(vm_args));
   vm_args.version = JNI_VERSION_1_2;
   vm_args.nOptions = 1;
   vm_args.options = options;
   status = JNI_CreateJavaVM(&jvm,(void**)&env,&vm_args);

   if (status != JNI_ERR)
   {
      cls = (*env)->FindClass(env, "HelloWorld");
      if (cls != 0)
         {mid = (*env)->GetStaticMethodID(env,cls,"Test","(I)I");
      if (mid != 0)
         {square = (*env)->CallStaticIntMethod(env,cls,mid,5);
      printf("Result of int Method:%d\n", square);

      (*jvm)->DestroyJavaVM(jvm);
      return 0;
   }
   else
      return -1;
}
#include <stdio.h>
#include "jni.h"

int main()
{
   JavaVMOption options[1];
   JNIEnv *env;
   JavaVM *jvm;
   JDK1_1InitArgs vm_args;
   long status;
   jclass cls;
   jmethodID mid;
   jint square;
   jboolean not;

   options[0].optionString="-Djava.class.path=.";
   memset(&vm_args, 0, sizeof(vm_args));
   vm_args.version = JNI_VERSION_1_2;
   vm_args.nOptions = 1;
   vm_args.options = options;
   status = JNI_CreateJavaVM(&jvm,(void**)&env,&vm_args);

   if (status != JNI_ERR)
   {
      cls = (*env)->FindClass(env, "HelloWorld");
      if (cls != 0)
         {mid = (*env)->GetStaticMethodID(env,cls,"Test","(I)I");
      if (mid != 0)
         {square = (*env)->CallStaticIntMethod(env,cls,mid,5);
      printf("Result of int Method:%d\n", square);

      (*jvm)->DestroyJavaVM(jvm);
      return 0;
   }
   else
      return -1;
}

Nur leider erkennt er die Datentypen JavaVMOption und JavaVMInitArgs nicht. Sie sind auch nicht in der jni.h datei zu finden. Den Code hab eich zwei PDFs. Lider wird da nicht gesagt, welche jni.h Datei verwendet wird.
