Cmd Prompt qustion

[Chris]

All,
I am looking to interact with the command prompt on my Windows XP
(sp2) system. I have reread books and followed message board threads
and have found success in executing cmd.exe and loading up a batch
file.
However, now that the batch has loaded and I can see it, I am trying
to interact with it through my java project. (By intereact I mean pass
arguments and text to it). Here's where I get stuck... Does anyone
know how I can accomplish this?

Thank you very much for your time.

{
String intel = "C://arconsole.bat";

Runtime rt = Runtime.getRuntime();

Process pr = rt.exec(intel);

BufferedReader input = new BufferedReader(new
InputStreamReader(pr.getInputStream()));

String line=null;

while((line=input.readLine()) != null)
{
System.out.println(line);
}

int exitVal = pr.waitFor();

System.out.println("Exited with error code
"+exitVal);
}

catch(Exception e)
{
System.out.println(e.toString());
e.printStackTrace();
}
}
}

String intel = "C://arconsole.bat";

Runtime rt = Runtime.getRuntime();

Process pr = rt.exec(intel);

For passing command line args I would try:

String[] intel = { "cmd", "/c", "C:\\arconsole.bat", "foo", "bar" };
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(intel);

And I would give up trying to make real interaction with the
app being run.

PM Steven Harper is fixated on the costs of implementing Kyoto, estimated as high as 1% of GDP.
However, he refuses to consider the costs of not implementing Kyoto which the
famous economist Nicholas Stern estimated at 5 to 20% of GDP
