We're doing it manually because the original idea was that the admin 
service could manage multiple organizations  (a SaaS), so you'd have to 
set up the cookie path's correctly.

For your app, it sounds like @RolesAllowed will work.  You just have to 
set up the appropriate web.xml security constraints for your REST urls 
in web.xml.  Just set up the REST apis to require authentication and let 
@RolesAllowed do the rest.  The keycloak jboss/wildfly adapter can 
handle BEARER token auth at the same time as regular browser oauth.  If 
the server is initiating the login, then you can just follow the current 
keycloak examples.  If not, then the Javascript lib Stian wrote is an 
option (and something we'll have to document).
