Use of waitFor() method after exec()

[Gaelle]

Hi !

I don't manage to use the waitFor() method the way I want :
I have a web application in JSP which makes a command line call by :
Process p = r.exec(command);
This command creates a file I have to dispaly in a frame.
So I have to wait for the file to be created before I load it in my frame.
I have written :
int respro = p.waitFor();
But it doesn't seem to really wait, and I get the URL not found message in my frame.

Can anyone explain me exactly how waitFor() works, and if it's what I need ?

Thanks !

Are you sure that your error comes from the

WaitFor

method ?
I mean, can't it be the command that you execute that doesn't work ?
Did you check the

respro

value that returned the

WaitFor

method (it's your commande return value) ? Water is not bad as soon as it stays out human body ;-)

I am having a similar problem with waitFor(). You are not
alone! I have never had this happen but I believe the
waitFor is supposed to wait for the child process to end
before parent continues. My exitValue is '0' as soon as the
frame opens and stays zero after it closes. If this is not
the way to wait for the
Process p = Runtime.getRuntime().exec(command);
p.waitFor();
then I would sure like to know.
