Process Builder Question

[Chris]

All- I type the following into my command prompt and it works fine:

DogTrainingCommand.exe /text="Testing 123, Testing 123." /voice="dog"

(that is once I have done: cd C:/Program Files/PetTraining/T120)

However, when I try to automate this using ProcessBuilder in a java
app nothing happens? My program terminates as soon as I run it and I
get no output. Can you correct me in what I am doing wrong?
Thank you in advance for your time!


import java.io.IOException;
import java.io.*;

public class CmdPrompt {
public static void main(String args[])
{
try {
ProcessBuilder pb = new
ProcessBuilder("DogTrainingCommand.exe", "\\text = Testing 123,
Testing123", "\\voice = dog");
pb.directory(new File("C:\\Program Files\\PetTraining\
\T120"));
Process p = pb.start();
}
catch (IOException e)
{
}
}

}

Why are you "escaping" a / to \\ ??

you need to start a thread or two, to read from p.getInputStream() and
p.getErrorStream(), and do the "right thing" with that data.

Thank you for your advice, after reediting, I guess my question more
specifically is with the arguments that I need to pass. That is, I use
forward slashes, quotes, and parenthesis in the command line and it
seems like that is what is tripping this up. Are there characters that
I need to encompass quotes, slashes, and parentheses with for the
arguments to pass?
Thank you.
