Re: [Zope-dev] Extrenal method unable to run the os.popen() or os.system() commands
Oh yes, i forgot to mention that in my code i did use the absolute paths to my
java .jar file as you can see i my code below, the absolute path to the
Extensions directory is in the variable homedir. I also set my classpath to
point to the folder just in case..
Any ideas why it won't work? and any suggestions for workarounds?
Thanks!
homedir = os.getcwd()
homedir = homedir + "/Extensions"
command = "cd "+homedir
os.popen(command)
command = "java -jar "+ '"' + homedir + "/" + "ActiveLearningTools.jar" + '" ' +
"prepArticles >> test.txt"
os.popen(command)

Re: [Zope-dev] Extrenal method unable to run the os.popen() or os.system() commands
Hi,
Since you say changing the working environment in zope is dangerous, is there
any way around for what i need to do?
Is there a way i can find out the exact directory zope is on at that moment?
and if i can find it is it a good idea for me to place the additional files i
need to run my .jar in that directory?
Or should i just do everything in an absolute path method?
i.e when i wanna run my jar instead of using this as my "command"
java -jar ActivelearningTools.jar >> output.txt
I will do:
java -jar
/var/lib/zope2.8/instance/plone-site/Extensions/ActiveLearningTools.jar >>
/var/lib/zope2.8/instance/plone-site/Extensions/output.txt
Thanks in advance!

This "popen" is useless.
It will change the working directory in the new (!) process that executes
"command". But the effect is lost as soon as the process ends (after the
"cd" has been executed).
"os.popen('cd ...')" will not affect the working directory
of the Zope process (or any later 'os.popen').
Be warned: you should *not* change Zope's working directory.
Changing global resources (such as the working directory) is
dangerous in a multi thread environment (such as Zope).

[Zope-dev] Extrenal method unable to run the os.popen() or os.system() commands
Hi guys...
I wrote an external python script which would grab some HTML and so some text
and file preprocessing.
The script then is supposed to run come command line methods... using
os.system() .. however when i run the script triggered by my DTML code it
manages to do the grabbing of the html and saving it into a file ans stuff...
but once it hits the portion where its supposed to run the command lines.. it
just skips everything and goes right to the end after which this error
message is shown :
Error Type
IOError
Error Value
[Errno 2] No such file or directory:
'/var/lib/zope2.8/instance/plone-site/Extensions/output.txt'
Request made at
If the command line executables had run this error would not occur as one of
the jar files was supposed to output a text file called output.txt.
I tried running this script, modified on its own off the terminal using "python
test.py" and it works perfectly... but once DTML calls this script it is unable
to run the cammand line portion...
can anyone please help me out or point me in the right direction...
Thanks and regards
wan
