Have you tried running it as a spawned job from the shell? If something is pooched in the environment then the job should hang (then you know it is not a zope problem).

Subject: [Zope] Problems Executing pdftk from within zope.


Hello Zopistas...

I trying to modify pdf files from within zope.
I use the following command:

'/usr/bin/pdftk /t/in.pdf attach_files /t/a1.pdf /t/a2.pdf output /t/out.pdf'

When I execute it as root it works...

When executed from within zope,
(this i've done via external command that executes os.system(...))
A task is started to executed it, but the task hangs.

Even with set the setuid bit on /usr/bin/pdftk, making the zope spawned task
run as root the command just hangs....
(I've confirmed that the task is actually running as root!)

I'm sure I've forgoten something silly,
but after bashing it around for several hours I just can't figure out
why it hangs

Any suggestions at what the problem could be are welcome 8-)

Jerry
P.S. Here my Control panel info, incase it's relevant....
