Hi again,
just tried to deploy the latest OGCServer. took it from github and
adjusted the ogcserver.conf and map_factory.py files, but now I am
getting the following error in the apache log:
[info] mod_wsgi (pid=13502, process='kofserver3', application=''):
Loading WSGI script '/srv/www/wsgi/wms_osm.wsgi'.
[error] mod_wsgi (pid=13502): Target WSGI script
'/srv/www/wsgi/wms_osm.wsgi' cannot be loaded as Python module.
[error] mod_wsgi (pid=13502): Exception occurred processing WSGI script
'/srv/www/wsgi/wms_osm.wsgi'.
[error] Traceback (most recent call last):
[error] File "/srv/www/wsgi/wms_osm.wsgi", line 6, in <module>
[error] application = WSGIApp('/opt/OGCServer/conf/ogcserver.conf')

in __init__
[error] self.mapfactory = getattr(mapfactorymodule,
'WMSFactory')(configpath)
[error] TypeError: __init__() takes exactly 1 argument (2 given)
ogcserver setup shows no error and I can import it to python, but have
there been any changes to wsgi support?
unfortunately I cant make out what exactly causes this error and I'll go
back to the old version of OGCServer (from ~March 2011).
BTW, just in case someone has an idea... I use these settings:
****
map_factory.py:
****
#!/usr/bin python
from ogcserver.WMS import BaseWMSFactory
class WMSFactory(BaseWMSFactory):
def __init__(self):
BaseWMSFactory.__init__(self)
self.loadXML('/opt/mapnik/osm_map.xml')
self.finalize()
****
wsgi server script:
****
#!/usr/bin python
import sys
from ogcserver.wsgi import WSGIApp
sys.path.append('/opt/OGCServer/conf/')
application = WSGIApp('/opt/OGCServer/conf/ogcserver.conf')
****
Apache config:
****
WSGIDaemonProcess server3 processes=10 threads=1 display-name=%{GLOBAL}
WSGIApplicationGroup %{GLOBAL}
WSGIProcessGroup server3
WSGIScriptAlias /osm /srv/www/wsgi/wms_osm.wsgi
LogLevel debug

Thanks Manel & Jukka,
Had no time to try the latest OGCServer version and I am a bit reluctant
to change my running system again...
The GWC that comes with GeoServer has a different structure. I am
actually not sure about the following <bean> from
WEB-INF/geowebcache-core-context.xml:
<bean id="gwcWMSConfig"
class="org.geowebcache.config.GetCapabilitiesConfiguration">
<constructor-arg ref="gwcGridSetBroker"/>
<constructor-arg
value="http://localhost/osm?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities"/>
<constructor-arg value="image/png,image/png8,image/jpeg"/>
<constructor-arg value="3x3"/>
<constructor-arg value=""/>
<constructor-arg value="false"/>
</bean>
Any vendor specific parameters should go into the 5. empty
constructor-arg and it seems to me that something is needed there to let
mapniks GetCap show up. I already tried many combinations without success.
Anyway, the changes made to OGCServer look like they may solve this.
I'll report back.
thanks
Daniel

Hi,
I am running GeoWebCache which comes with GeoServer and the config
file "geowebcache.xml" has this kind of entry
<wmsLayer>
<name>GWC_service</name> <!-- this is what is published to the outside
world -->
<wmsUrl><string>http://server.fi/cgi-bin/mapserv.exe</string></wmsUrl>
<!-- the url of your wms map -->
<wmsLayers>WMS_layer1</wmsLayers> <!-- layer names as known by your
wms -->
I am not sure if GWC is reading the GetCapabilities ever, it just
starts to send GetMaps when seeding the cache. However, the standalone
service may behave differently.

Hi Daniel,
You may try a newer OGCServer version[1]. Perhaps GWC doesn't
like the GetCapabilities OGCServer is sending, and the newer
version has a lot of improvements in this area.
Also, if it does not work with the new version, please open a
bug on github and post any debug info from GWC.
Manel.

Asunto: [Mapnik-users] howto config GeoWebCache in front of
mapnik/ogcserver?
Hi!
is there someone out there using GWC with Mapnik?
I saw some older posts, but none including details on GWC
configuration.
My question is:
whats the trick when adding the GetCapabilities to the
'gwcWMSConfig'-bean in GWCs geowebcache-core-context.xml?
I supposed this would work, but it didnt:
<constructor-arg
value="http://localhost/osm?service=WMS&version=1.1.1&
request=GetCapabilities"/>
(without the line break of course)
I have mapnik 0.7.1, GWC 1.2.6 standalone (not the GS plugin) and a
valid GetCap from OGCServer, but none of the settings I tried
gave me a
demo-layer after reloading the tomcat app.
I also tried setting the empty arg to
<constructor-arg value="module=map_factory"/>
and the likes, but nothing.
I keep on digging, but maybe someone just knows whats missing.
thanks in advance...
