I have built a plugin for rudimentary parsing of WMS service descriptors.
The content type for that is:
application/vnd.ogc.wms_xml
I have the plgin built by ant, tested by ant and all. Now I add the
plugin to my registered extension points and hadoo.log shows the plugin
is being loaded:

However, nutch seems to ignore the plugin.
2008-11-27 17:23:01,350 WARN parse.ParseUtil - No suitable parser found
when trying to parse content
http://isk.geobasis-bb.de/ows/dnm025.php?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.2.0
of type application/vnd.ogc.wms_xml
I added the plugin to the parse-plugins.xml file:
<!-- types for wms stuff -->
<mimeType name="application/vnd.ogc.wms_xml">
<plugin id="parse-wms" />
</mimeType>
[...]
<alias name="parse-wms" extension="info.geometa.parse.wms.WMSParser" />
What gives??
