Darrell, Infinispan is tightly integrated with AS7 and yes, as you can imagine, Infinispan relies on the clustering infrastructure provided by AS7 which is also based on JGroups.
So, you can forget about handling the clustering details in your own code.
Assuming that your only Infinispan usage is limited to 2LC, all you need to do when hooking Hibernate with Infinispan 2LC is explained in https://docs.jboss.org/author/x/LoJ7 (see section on Infinispan second level cache).
If you have other Infinispan use cases, such as deploying your own Infinispan instances in AS7, https://docs.jboss.org/author/x/JwBo should help.
Thanks, great news. I'm really impressed with the entire AS7 stack, and the tight integration of Infinispan with it is really going to simplify our lives.
I'm still a little confused. I need to use infinispan in replicated mode among multiple instances of JBoss AS.
In order to do it, do I need to set up a jboss cluster using domain mode? Or should I just start infinispan in every JBoss instance and it is infinispan that automatically sets up a cluster?
