Dear sir,
I use the JNI sun example, It compile and build a .exe, but no run well.

The code:

#include <jni.h>
main()
    {
    JNIEnv *env;
    JavaVM *jvm;
    JDK1_1InitArgs vm_args;
    jint res;
    jclass cls;
    jmethodID mid;
    jstring jstr;
    jobjectArray args;
    /* IMPORTANT: specify vm_args version # if you use JDK1.1.2 and
beyond */
    vm_args.version = 0x00010001;
JNI_GetDefaultJavaVMInitArgs(&vm_args);
    res = JNI_CreateJavaVM(&jvm,&env,&vm_args);
        if (res < 0) {
        fprintf(stderr, "Can't create Java VM\n");
        exit(1);
        }
    cls = (*env)->FindClass(env, "Prog.class");
        if (cls == 0) {
        fprintf(stderr, "Can't find Prog class\n");
        exit(1);
        }
    mid = (*env)->GetStaticMethodID(env, cls, "main",
"([Ljava/lang/String;)V");
    if (mid == 0) {
     fprintf(stderr, "Can't find Prog.main\n");
        exit(1);
        }
    jstr = (*env)->NewStringUTF(env, " from C!");
    if (jstr == 0) {
     fprintf(stderr, "Out of memory\n");
  exit(1);
     }
    args = (*env)->NewObjectArray(env, 1, (*env)->FindClass(env,
"java/lang/String"), jstr);
    if (args == 0) {
     fprintf(stderr, "Out of memory\n");
  exit(1);
     }
    (*env)->CallStaticVoidMethod(env, cls, mid, args);
    (*jvm)->DestroyJavaVM(jvm);
}

The Java program:

//////////////////////////PROG.JAVA////////////////////////////////

public class Prog {
 public static void main(String[] args) {
  System.out.println("Hello World");
 }
}



The error:

can't fing Prog class

The . is in the classpath, Prog.class is in . directory.


Please, send me faster, Thank you
