Problem executing an exe executable!

[mohsen_fakhari]

Hello
I'm trying to run a exe file named butil.exe from within a java
application.
This is my code:

Process p = run.exec("d:\\modec160\\p_21\\butil.exe");
BufferedReader err =new BufferedReader(new
InputStreamReader(p.getErrorStream()));
BufferedReader in = new BufferedReader(new
InputStreamReader(p.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}

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

int exitValue = p.waitFor();
System.out.println("Process exit value: " + exitValue);

exitValue is always 2.
Like many other programms 'butil' when run without any arguments will
give a usage discription,
but I don't have anything.
When I give its arguments,it should create a text file but I don't have
it too.
If it is important butil belongs to Btrieve,an old record manager and
I'm using JDK1.4 on winXP

Any thing you think may help,may really help.

Thank you.

Return code 2 on Windows means that the file 'd:\\modec160\\p_21\\butil.exe'
does not exist. Perhaps you've just mistyped the path? By the way, here's a
link to the full set of Windows return codes:

Also, I found this article very useful in helping me with problems in
running executables:

Hi
I think there should be another missed file,because the path is correct
and
when I change the path to an incorrect path(e.g. buti.exe instead of
butil.exe)
I got another error:
java.io.IOException: CreateProcess: d:\modec160\p_21\buti.exe error=2

Thank you

I read the document in JavaWorld too.
It was helpfull and I know a lot more now,
but there it didn't help me

If the error is from Butil then the error 2 could represent a corrupt
btrieve file. Do you get this error from just running the command line
utility by itself.

Running butil in cmd I have such a thing:
Btrieve Utilities Version 5.12
Copyright 1982 - 1990, Novell, Inc. All Rights Reserved.
Usage is BUTIL -CLONE <OUTPUT-FILE> <SOURCE-FILE> [-O<OWNER1>]
Usage is BUTIL -COPY <INPUT-FILE> <OUTPUT-FILE> [-O<OWNER1>
[-O<OWNER2>]]
Usage is BUTIL -CREATE <FILE-NAME> <DESCRIPTION FILE>
Usage is BUTIL -DROP <BTRIEVE-FILE> <KEY NUMBER> [-O<OWNER>]
....

But from within my java code I receive nothing

Hi all
If it may help:
I created a bat file with instructions to run butil and then
tried to run this bat file from within my java code.
Surprisingly it works!
I've error messages I should and whith correct arguments I've correct
resulted files.

I'm still eager to do it by pure java.

Thank you
