Hi,
thanks Alexandre, my server is running now. But we had some troubles to get
him running in conjunction with my special XML-style. There are some
restrictions, which are not comfortable for us. Here a short summary:
1. The WMSFactory from the tracticket didn't worked. We had to change it to
this:
from mapnik.ogcserver.WMS import BaseWMSFactory
from mapnik import *
class WMSFactory (BaseWMSFactory):
def __init__ (self):
BaseWMSFactory.__init__(self)
self.loadXML ( "/mapnik/style.xml")
self.finalize ()
2. Added default styles so that they do not have to be specified each time
in the WMS request.
You have two possibilities:
* if style names = layer names, just do a WMS request as usual.
* if not, you have to specify your styles in the WMS request.
Detail: in /usr/lib/python2.4/site-packages/mapnik/ogcserver/cgiserver.py
def process(self, req):
reqparams = lowerparams(req.params)
if len( reqparams[ "styles" ] ) < 1:
reqparams[ "styles" ] = reqparams[ "layers" ]
.....
3. In the implementation, it was mandatory to have the styles named exactly
like the corresponding layers, which was making the WMS "STYLES" parameter
useless.
Removed the constraint by commenting out 2 lines in
/usr/lib/python2.4/site-packages/mapnik/ogcserver/common.py :
#if reqstyle and reqstyle not in layer.wmsextrastyles:
# raise OGCException('Invalid style "%s" requested for layer
"%s".' % (reqstyle, layername), 'StyleNotDefined')
cheers,
Jürgen
