Fw: [Zope] problem with the shapelib module.. help

[Allen Huang]

shapelib still didn't work for me.. help
 
I've being trying different things for the pass day
 
1. I put the shapefile directly in the Extensions with the external method and it work fine
        import shapelib, dbflib
        def readshp():
            shp = shapelib.ShapeFile('taiwan1.shp')
            return shp.info()

           and in zope
            <dtml-var expr="readshp()>
 
2. but when I save the shapefiles (taiwan1.shp, taiwan1.shx, taiwan1.dbf) into zope and call it using dtml it return the same error message. 
        import shapelib, dbflib
        def readshp(filename):
            shp = shapelib.ShapeFile(filename)
            return shp.info()

        and in zope
        <dtml-var expr="readshp(taiwan1.shp)">
                or
        <dtml-var expr="readshp('http://localhost/pytest/taiwan1.shp')">


The error message are

1. in "Run Zope in Console"
        Exception exceptions.AttributeError:"ShapeFile instance has no attribute 'thisown'" in     ignored
 
2. in web browser
    Site Error
    An error was encountered while publishing this resource. 
    Error Type: IOError
    Error Value: new_ShapeFile failed

 
is there something wrong with how I constructed it? Do I need to do something before hand?

3. in error_log
Traceback (innermost last):

Hmm. I doubt that you have really seen this text. There should be something
in between the "in" and the "ignored". It is *vital* that you
are as precise as possible in your problem reports...


Python emits messages of the kind above in some (rare) situations,
e.g. when exceptions occur in destructors.


The exception above seems to have been raised in such a situation.
The missing thing betwenn "in" and "ignored" should tell us which situation
this was.

It tells you that something tries to access the attribute "thisown"
on a "ShapeFile" instance but this does not have the attribute.

Another tip for the future. When you report problems, you need
to include full error information. Beside the "Error Type" and
"Error Value" above, this also includes the traceback.
You find all this information in the "error_log" object in
Zope's "Root Folder" (Management Interface).
