Execute a .exe file I created?

Question

I've written a c++ file and compiled it; I now have an executable. I decided it'd be nice to have a pretty interface, and I thought it'd be easy to throw one together in java, and just call the executable from my java program. However, I've run into some trouble trying to use the Runtime.exec() command.
I gather that the exec() command is good for shell commands, and evidently doesn't work for programs like mine. I was hoping to find a call similar to system(...) in c++, where it would execute the passed parameter as if it were on the command line (I know that's not what Runtime.exec() does). Could anybody tell me how to run an executable I've written from within java? Thanks.
(this is what I wrote:)cmd[0] = "cmd.exe";
cmd[1] = "/C" ;
cmd[2] = "VBDoc";
Process proc = runtime.exec(cmd);where "VBDoc" is the program I've written already, and I capture the output of the call.
I get:
ERROR>'VBDoc' is not recognized as an internal or external command,
ERROR>operable program or batch file

Several things:
(1)I've included the file extension, and now it hangs - which is odd, because I included a "streamGobbler" thread as was encouraged in that write up to "promptly ... read the output stream of the subprocess". At least it's a different problem now. =)
(2)Mark, you indicated in your first post that the entire path needed to be explicitly included, which I'm not convinced of: as I mentioned earlier, I included the executable's directory in the system path variable, so it can be executed from anywhere
(3)Before I noticed all the latest replies to this question, I got Visual Studio installed on my computer and whipped together a VB GUI that solves my problem. <=\
I'm still interested as to how I can execute the file, though. If any one is still interested, here's the code:import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.filechooser.*;

        //need to refer to it.
