[infinispan-dev] ISPN-185: Injecting a running JGroups channel into Infinispan

Regarding ISPN-185 [1] (Need to provide a mechanism in which a JGroups channel can be passed in), I'd like to discuss a few solutions. I believe this directly affects the way JBoss AS will use Infinispan, so it would be good to hear from JBoss AS folk on this subject. :) Transport [2] is an interface that wraps up the JGroups Channel (among other things), and the default (only?) implementation so far is the JGroupsTransport [3]. Now one thing we can do to support channel injection is to actually support Transport injection. This way a Transport can be constructed (simple constructor), the JGroups channel set, and the transport passed in to a GlobalConfiguration instance (setter TBD), which is then in turn passed to a DefaultCacheManager constructor [4]. The problem with this approach though, is that it will only work for programmatic configurations. To support declarative configurations as well, we'd need to override the relevant DefaultCacheManager constructors [5] [6] [7] [8] to accept a Transport as well. But this pollutes the CacheManager API, in my opinion. So, how important is it that a running channel is used to override something defined in XML?
