I'd like to use a MongoDB database from GeoServer. There seems to be a GeoTools plug-in available (http://repo.opengeo.org/org/geotools/gt-mongodb/), and I've dropped the latest version (8.2) into the webapps\geoserver\WEB-INF\lib folder and restarted, but it doesn't show up in the new data source list within Geoserver.
Any ideas?
I'm using GeoServer 2.2 on Windows 7 64-bit.
