Sending commands to jar with c++

I ran a .jar file (in c++) like so:

#include <iostream>
#include <windows.h>

using namespace std;

int main ()
{
    system("java -jar filename.jar");
    return 0;
}

Note: This runs perfectly just the way I want it, but how to I send commands to the jar app with c++ code? I know I can't do system("MyJavaAppCommand"); since that would just be executed by the windows command and not my app's. Thanks in advance.

You can just add arguments after "filename.jar". These values will be seen by Java inside the argc[] array in the usual public static void main(String argc[]) method.

I would try using command line arguments like

system("java -jar filename.jar arg1 arg2 ... argN");

There arguments are passed to your main method in

public static void main(String... args)

or

public static void main(String[] args)

Too many references to include here
