Dear all,
I want to save the file on filebased system. i am using urllib

here i tried with this code

*import urllib

# fill these in
filetitle='a nice test picture'

class MyUrlOpener(urllib.FancyURLopener):
   def prompt_user_passwd(self, host, realm):
        return (user,password)
   def __init__(self, *args):
      self.version = useragent
      urllib.FancyURLopener.__init__(self, *args)

def main():
       # use authentication and set the user agent
       urllib._urlopener = MyUrlOpener()

       # read the contents of filename into filebody

       # urlencode the id, title and file
       params = urllib.urlencode({'id': filename,

       # send the file to zope
       f=urllib.urlopen(addfileurl, params)

if __name__ == '__main__':

when i compile this file with simple python demo.py it gives me error
Traceback (most recent call last):
  File "demo.py", line 36, in ?
  File "demo.py", line 33, in main
    f=urllib.urlopen(addfileurl, params)
  File "/usr/lib/python2.4/urllib.py", line 84, in urlopen
    return opener.open(url, data)
  File "/usr/lib/python2.4/urllib.py", line 192, in open
    return getattr(self, name)(url, data)
  File "/usr/lib/python2.4/urllib.py", line 272, in open_http
    import httplib
  File "/usr/lib/python2.4/httplib.py", line 70, in ?
    import mimetools
  File "/usr/lib/python2.4/mimetools.py", line 6, in ?
    import tempfile
  File "/usr/lib/python2.4/tempfile.py", line 33, in ?
    from random import Random as _Random
  File "/usr/lib/python2.4/random.py", line 43, in ?
    from math import log as _log, exp as _exp, pi as _pi, e as _e
ImportError: /usr/lib/python2.4/lib-dynload/math.so: undefined symbol:

so i compiled with this command *python2.4 demo.py* it does not give any
but it does not give me output to when i check my directory where i am
trying to save my jpeg file *
http://localhost:8080/starinstance/bin/manage_addFile *there i do not find
that file it means it is not able to store that file.

i do not know what i am trying to do..could any one please give me idea how
may i store the file on file system.
i created a html page
     <form name="demo" method="post" ENCTYPE="multipart/form-data"
    <fieldset style="width:20%">

        Id:<input type="text" name="title" id="title"/><br><br>
        Name:<input type="text" name="name" id="name"/><br><br>
        Keywords:<input type="text" name="keywords" id="keywords"/><br><br>
        <input type="file" name="upload" id="upload"/><br><br>
        <input type="submit" name="submit" value="Save" id="submit"/><br>
once if user select any file it should store to specific location *

*Any suggestion will be appreciable
