OK,
I replaced the __init__.py and now when Apache
Restarts I get:
---------------------------
Mod_python error: "PythonHandler jToolkit.web"
Traceback (most recent call last):
File "C:\Python22\Lib\mod_python\apache.py", line
335, in HandlerDispatch
result = object(req)
File
"C:\Python22\Lib\site-packages\jToolkit\web\__init__.py",
line 93, in handler
server = getserver(modulename, instancename)
File
"C:\Python22\Lib\site-packages\jToolkit\web\__init__.py",
line 67, in getserver
module = __import__(modulename, globals(),
locals(), [instancename])
File "C:/Program Files/Apache
Group/Apache2/htdocs/\jtoolkit\demo\helloworld.py",
line 24, in ?
class HelloWorldServer(server.AppServer):
File "C:/Program Files/Apache
Group/Apache2/htdocs/\jtoolkit\demo\helloworld.py",
line 26, in HelloWorldServer
serverclass = HelloWorldServer
NameError: name 'HelloWorldServer' is not defined
========================
However, If I refresh the page I get
Mod_python error: "PythonHandler jToolkit.web"
Traceback (most recent call last):
File "C:\Python22\Lib\mod_python\apache.py", line
335, in HandlerDispatch
result = object(req)
File
"C:\Python22\Lib\site-packages\jToolkit\web\__init__.py",
line 93, in handler
server = getserver(modulename, instancename)
File
"C:\Python22\Lib\site-packages\jToolkit\web\__init__.py",
line 78, in getserver
raise AttributeError(errormessage)
AttributeError: module 'demo.helloworld' has no
attribute 'HelloWorldConfig'
module is <module 'demo.helloworld' from 'C:/Program
Files/Apache
Group/Apache2/htdocs/jtoolkit/\demo\helloworld.pyc'>,
attributes are ['__builtins__', '__doc__', '__file__',
'__name__', 'server', 'widgets']
Python path is ['C:/Program Files/Apache
Group/Apache2/htdocs/jtoolkit/\\', 'C:/Program
Files/Apache Group/Apache2/htdocs/\\',
'C:\\Python22\\Lib\\site-packages\\Pythonwin',
'C:\\Python22\\Lib\\site-packages\\win32',
'C:\\Python22\\Lib\\site-packages\\win32\\lib',
'C:\\Python22\\Lib\\site-packages',

'C:\\Python22\\Lib\\lib-tk', 'C:\\Program
Files\\Apache Group\\Apache2', 'C:\\Program
Files\\Apache Group\\Apache2\\bin', 'C:\\Python22']
=======
Ok, well I had to tweak the httpd.conf to get this far
look like
<Directory "C:\\Program Files\\Apache
Group\\Apache2\\htdocs\\jtoolkit">
SetHandler python-program
PythonHandler jToolkit.web
#PythonOption jToolkit.module
jtoolkit.demo.helloworld
PythonOption jToolkit.module demo.helloworld
PythonOption jToolkit.instance HelloWorldConfig
PythonDebug On
</Directory>
So, I went interactive on this and here is what I got:
>>> from demo import helloworld
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
File
"C:\PYTHON22\LIB\SITE-PACKAGES\JTOOLKIT\demo\helloworld.py",
line 24, in ?
class HelloWorldServer(server.AppServer):
File
"C:\PYTHON22\LIB\SITE-PACKAGES\JTOOLKIT\demo\helloworld.py",
line 26, in HelloWorldServer
serverclass = HelloWorldServer
NameError: name 'HelloWorldServer' is not defined
>>> import demo
>>> dir(demo)
['__all__', '__builtins__', '__doc__', '__file__',
'__name__', '__path__', 'helloworld']
>>> from demo import helloworld
>>> dir(helloworld)
['__builtins__', '__doc__', '__file__', '__name__',
'server', 'widgets']
>>>
So I think I must have something configured
incorrectly in either my httpd.conf or PYTHONPATH.
Could it be my python version?
Perhaps I should just start over. Let me know if you
have any ideas. I hate to waste your time.
I have access to an openBSD server that I may try
installing this on. My problem there is that I
usually have to set the python path in the
application. (or I just dont know how to set it on
openBSD yet. )
