One thing to note: Vista does not come with Java installed. In fact, it
does not even tell you how to install it if needed. I just downloaded from

Hi,
The Following is working on Win9.x up to XP, but not under Vista.

HINSTANCE lib = LoadLibrary(szFullAbsolutePathToJavaJVM_DLL);

if(lib == NULL || lib == 0){
trace(_T("Couldn't find the jvm.dll"));
return FALSE;
}

lib is always 0.
GetLastError(); returns too always 0

If found that:

Some advice ?

I use this stuff to call Java from c++, it is all working very stable
to now !

best Regards,
David

I found it out. When i call LoadLibrary, the DLL Init Method of
jvm.dll is called and it is searching the Enviorenment Variables for
the %JAVA_HOME% Path. This path was not set on the Testing Vista, when
i set, all works fine !
