[Geoserver-users] Error setting up GeoFence 2.2 with GeoServer 2.7.3-1

I'm trying to get GeoFence 2.2 working with GeoServer 2.7 and I've followed the instructions referenced on this page:

https://github.com/geoserver/geofence/wiki/First-steps

When I try to test the connection from GeoFence to GeoServer, it connects with no problems. However, when I try to perform a "Test Connection" from GeoServer to GeoFence, I get the following "500 Internal Server Error":

org.springframework.remoting.RemoteAccessException: Could not access HTTP invoker remote service at [http://localhost:8081/geofence/remoting/RuleReader\]; nested exception is java.io.IOException: Did not receive successful HTTP response: status code = 500, status message = [Internal Server Error]

Any ideas as to what might cause this?

TIA,

Paul
