Java HotSpot Virtual Machine

Hi all,

I tried to create a JVM instance as laid out in the examples. The JVM is never getting created. I am using Visual C++ (I need to, when the code works I will be creating a DLL that is an addon to someother piece of software).

I have posted the code below::

#include "stdafx.h"
#include "invoke2.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

/////////////////////////////////////////////////////////////////////////////
// The one and only application object

CWinApp theApp;

using namespace std;

int main(void)
{
	int nRetCode = 0;

	// initialize MFC and print and error on failure
	if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
	{
		// TODO: change error code to suit your needs
		cerr << _T("Fatal Error: MFC initialization failed") << endl;
		nRetCode = 1;
	}
	else
	{
		JNIEnv *env;			/* The java vm environment								*/
		JavaVM *jvm;			/* The actual jvm										*/
		CString fname;			/* The file name of the generated intermediate obj file */
		JDK1_1InitArgs vm_args;
		jint res;
		jint vmavail;
		jclass cls;
		jmethodID mid;
		//char classpath[4096];
		bool viewerready;		/* is this java viewer valid?							*/
		vm_args.classpath=".";
		vm_args.version = JNI_VERSION_1_4;
		vmavail=JNI_GetDefaultJavaVMInitArgs(&vm_args);
		if(vmavail < 0)
		{
			AfxMessageBox(" That VM version is not available. ",100,100);
			viewerready=false;
			jvm=NULL;
			env=NULL;
		}
		else
		{
			vm_args.classpath=".";
			res = JNI_CreateJavaVM(&jvm,(void **) &env,&vm_args);
			if(res < 0)
			{
				AfxMessageBox("Could not create JVM instance. \n Check your classpath. \n 3D viewer will not be available. ",100,100);
				jvm=NULL;
				env=NULL;
				viewerready=false;
			}
			else
			{
				cls = env->FindClass("OBJViewer");
				if(cls == 0)
				{
					AfxMessageBox("Can't find the java OBJViewer class. ",100,100);
					viewerready=false;
				}
				mid = env->GetMethodID(cls, "OBJViewer", "");
				if(mid == 0)
				{
					AfxMessageBox(" java class OBJViewer has no constructor OBJViewer() ");
					viewerready=false;
				}
				env->CallStaticVoidMethod(cls, mid);
			}
		}
	}

	return nRetCode;
}
