Urgent!! i need help on invoking the JVM from C++

Question

Hi.. I have tried invoking the JVM and calling a java class through c++ but all i get is "can' find class java.lang.NoClassDefFoundError (Wrong class path?)
anyone has any ideas as to what i need to do.. i have set the path and classpath variables to my <jre>\bin\classic and <jre>\bin
here is the code..
//MyCApp2.cpp//
#include <windows.h>
#include <stdio.h>
#include <jni.h>
#define MAIN_CLASS "myApp1"
int main(int argc, char** argv)
JNIEnv               *env;
JavaVM               *jvm;
JDK1_1InitArgs     vmargs;
jint               rc;
jclass               cls;
jmethodID          mainId;
// get classpath env setting
char* szClasspath = getenv("CLASSPATH");
vmargs.version = 0x00010001; // version 1.1
int temp = JNI_GetDefaultJavaVMInitArgs(&vmargs);
// the classpath returned by JNI_GetDefaultJavaVMInitArgs is wrong
vmargs.classpath = szClasspath;
printf("\nclasspath ,%s\n\n",vmargs.classpath);
rc = JNI_CreateJavaVM(&jvm, (void**)&env, &vmargs); // create the jvm
if(rc <0 )
     printf("Can't create Java VM ,%d\n",rc);
     return 1;
printf("Passed the CreateVM Stage");
// load the class containing the static main ()method
cls = env->FindClass(MAIN_CLASS);
if ( cls == 0 )
     printf("Could not find class %s\n",MAIN_CLASS);
     return 1;
// find main method
mainId = env->GetStaticMethodID(cls,"main","([Ljava/lang/String;)V");
if (mainId ==0 )
     printf("Could not find main()\n");
          return 1;
env->CallStaticVoidMethod(cls,mainId, 0); // call main()
jvm->DestroyJavaVM(); // kill jvm
return 0;

You say you set your classpath to jre\bin and jre\bin\classic; did you include the path to MyApp.class?
Perhaps you forgot "."?
