Urgent: call a Dos application

When I run myDosApp.exe from DOS, a screen appears and my app runs fine. However,
when i use:

Process p = Runtime.getRuntime().exec(c:/myDosApp.exe); p.waitFor();

the app runs but I get no screen to appear thru my java app. I've heard of
using START in front of myDosApp.exe to get a DOS window, but the START command
throws off my p.waitfor(); and the waitfor() thinks it's done b4 myDosApp
actually finishes.

I need to know how to get myDosApp.exe to appear on the screen thru my java
app without using the DOS start command. Thank you

If your DOS program only produces console output and then terminates, you
could redirect the output to a file (c:/myDosApp.exe >output.txt) and then
show the contents of that file in a Java window. But if you want the DOS
program's window to be inside a Java window, where you perhaps key input and
it displays output, you can't do that in Java because it would be
platform-specific. You'd need some kind of native method to handle this.
