trouble with a pyya connection

[Jennifer Cranfill]

I'm new to openwfe, but very excited about the possibilities it
presents. I'm trying to setup a small python script that can connect
to openwfe, but I'm having trouble connecting.

Here is my script:
from openwfe.workitem import codec
from openwfe.workitem import StringAttribute
from openwfe.workitem import FlowExpressionId
from openwfe.rest.wlclient import WorkSession

workSession = WorkSession('localhost', 5080, 'bob', 'bob')


Here is the error I get:
Traceback (most recent call last):
  File "openwfe-example.py", line 10, in ?
    workSession = WorkSession('localhost', 5080, 'bob', 'bob')
  File "/shots/spi/tas/src/bright/workflow/openwfe-python-1.7.2-src/
openwfe/rest/wlclient/__init__.py", line 65, in __init__
    self.sessionId = getSession(self.url, username, password)
  File "/shots/spi/tas/src/bright/workflow/openwfe-python-1.7.2-src/
openwfe/rest/__init__.py", line 151, in getSession
    f = urlopen(request)
  File "/usr/local/lib/python2.4/urllib2.py", line 130, in urlopen
    return _opener.open(url, data)
  File "/usr/local/lib/python2.4/urllib2.py", line 364, in open
    response = meth(req, response)
  File "/usr/local/lib/python2.4/urllib2.py", line 471, in
http_response
    response = self.parent.error(
  File "/usr/local/lib/python2.4/urllib2.py", line 402, in error
    return self._call_chain(*args)
  File "/usr/local/lib/python2.4/urllib2.py", line 337, in _call_chain
    result = func(*args)
  File "/usr/local/lib/python2.4/urllib2.py", line 480, in
http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 500: Server Error

I have a fairly standard install, was there something I needed to
start before trying to connect with python? the webclient is working.
Any help would be greatly appreciated. Thanks!

The root error should be listed in logs/worklist.log. There should be
an exception stack trace there stating what's going wrong.

I don't know if you work in a Python-only shop, but have you checked
OpenWFEru (http://openwferu.rubyforge.org) ? OpenWFE main effort has
switched from Java to there.

Thanks for your quick response! Looks like the problem was that I had
http_proxy environment variables set.

Interesting... I was planning on using python to automate a lot of the
processes. Are pyyas supported with openwferu?

Thanks!

Ah, well done.

There are currently two approaches :

1).
Scott Stults is currently working on a port of OpenWFEru to Python.
But I don't know anything about the status of his work.
http://jmettraux.wordpress.com/2007/04/27/from-ruby-to-python/

Maybe that could be of interest for you.

2).
I'm currently working on adding the original OpenWFE REST interface to
OpenWFEru. It's an important step because of those already existing
(and used) python, perl and .net interfaces.

I hope to come up with something next week.

I'll certainly develop a simpler, more mature REST interface specially
for OpenWFEru after that initial port work. This newer REST interface
will certainly sport serialization to XML and to YAML / JSON.
