I am trying to add GriB reading capability to my Geoserver distribution (version 2.7.1.1, build date Jun 26, 2015). I am trying to use the plugin archive found at http://ares.boundlessgeo.com/geoserver/2.7.x/community-latest/
However, once I include all of the JAR files into .../geoserver/WEB-INF/lib/ and reboot the Geoserver instance, the Web Admin page returns a 503 error.
I have also tried copying all JARs save jettison-1.0.1 (to avoid overwriting the one in the main Geoserver distribution).
Would anyone have any insight why the GriB extension will not install properly, or which version of the extension I should be trying to install for GS 2.7.1.1?
