Invoking the JNI urgent

Question

Hi,
I am trying to invoke the jvm from c code. I m having a simple main class in the mentioned classpath
this c code is compiling without errors
but when i try to execute it im getting the following error
"The instruction at "0x004010c5" referenced memory at "0x00000000". The memory could not be "read"
And the program exits with a negative value for JNI_CreateJavaVM
Can anybody help me out of this.... v urgent
Thanks for ur time in advance
I have given my c code here (Moreover wat to do with jvm.lib and jvm.dll)
#include "jni.h"
#include<stdio.h>
#include<stdlib.h>
//#define PATH_SEPARATOR ';'
//#define USER_CLASSPATH "D:\\Workspace\\eclipse\\SunExample"
int main()
JavaVMOption options[3];
     JavaVMInitArgs vm_args;
     JNIEnv *env;
JavaVM *jvm;
long res;
     jclass cls;
jmethodID mid;
jclass jstr;
jclass stringClass;
jobjectArray args;
     options[0].optionString ="-Djava.class.path=D:\\Workspace\\eclipse\\SunExample\\";
     options[1].optionString = "-Djava.compiler=NONE";
     vm_args.ignoreUnrecognized = JNI_FALSE;
     options[2].optionString="-veribose:jni";
     memset(&vm_args,0,sizeof(vm_args));
     vm_args.version = JNI_VERSION_1_4;
     vm_args.nOptions = 3;
     vm_args.options = options;
     res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);
     if(res == JNI_ERR){
          printf("Error Creating JVM\n");
               return 1;
     else
          printf("Result is %ld",res);
     //res = JNI_CreateJavaVM(&jvm, &env, &vm_args);
     cls = (*env)->FindClass(env, "Prog");
     //mid = (*env)->GetStaticMethodID(env, cls, "main","([Ljava/lang/String;)V");
     mid = (*env)->GetStaticMethodID(env, cls, "main","([Ljava/lang/String;)V");
     if (mid == NULL) {
goto destroy;
     jstr = (*env)->NewStringUTF(env, " from C!");
if (jstr == NULL) {
goto destroy;
     stringClass = (*env)->FindClass(env, "java/lang/String");
args = (*env)->NewObjectArray(env, 0, stringClass, jstr);
     (*env)->CallStaticVoidMethod(env, cls, mid, args);
destroy:
if ((*env)->ExceptionOccurred(env)) {
(*env)->ExceptionDescribe(env);
(*jvm)->DestroyJavaVM(jvm);
     return 0;
Thanks, Manoj

Not sure, but those string assignments look mighty suspicious.
Have you triedd putting printfs in various spots?
