Here is a fragement of my code that does just that:
v8::Local<v8::Array> path = v8::Array::New(PathElems.size());
for(int i = 0; i < PathElems.size(); ++i)
path->Set(V8Int(i),V8Str(PathElems[i]));
req->Set(V8Str("PathElems"),path);
I am not certain how to create the Date() or RegExp() objects from C++.

I am not sure what you are trying to do here.

The source is the code to be executed. The filename is context
information for error reports.

I don't know if that can be done.
