wms server

[Luca Delucchi]

Hi i'm trying to configure the wms server, i read the manual in the
wiki, i did the map_factory [1], ocgserver.conf[2] e wms.py[3] but
when i try python wms.py i have this error

luca@LucaCasa:~/prova_mapnik_tile/mapnik$ python wms.py
Traceback (most recent call last):
  File "wms.py", line 24, in <module>
    from mapnik.ogcserver.cgiserver import Handler

line 29, in <module>
    from wms111 import ExceptionHandler as ExceptionHandler111

    from mapnik import Map, Color, Envelope, render, rawdata, Image,

what's wrong?

thanks

Is that not obvious?

'home/luca/..'  -->  '/home/luca/...' ?

What is likely happening there is that you have a Style name attached  
to a layer in your XML that does not exist or is misspelled:

(The behavior of the OGCServer is more strict that the standard  
mapnik.load_map() in this regard)

In the <Layer> definitions, look for instances of:

<StyleName>stylename</StyleName>

and make sure they have corresponding:

<Style name="stylename">...</Style>

Feel free to file a trac ticket requesting this error be more verbose.  
For example, it could output the actual name of the invalid style  
encountered, to make finding it more easy.
