"A domain is a management policy that applies to one or more servers/nodes, which may or may not be part of a homogenous group". When you think about it, a server-group, and a cluster are really the same thing, the only difference is that the cluster has an additional set of services that a basic group does not. This was what I meant by the cluster-service tag, a way to specify how a group would cluster a particular service (maybe not all services should be clustered). Although it was just something I through out there as an example. A better way likely exists -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536347#536347] Start a new discussion in Management Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
