What is jgroups used for in local cache with no clustering with shared (jdbc cacheloader) database datastore? I know the documentation says its a required library for JBC 3.0 but since we are using JBC 3 with the webapp in older version of Jboss AS (4.x) I want to know what will not work if I not deploy the jgroups with the webapp
You will still need it since JBC is compiled against JGroups and a lot of the internal components use JGroups building blocks. You will end up with class not found errors if you try and run JBC without JGroups.
