Hi Galder, I looked at the preliminary writeup for the New Fine Grained Replication API Design at http://community.jboss.org/wiki/newfinegrainedreplicationapidesign When compared to the POJOCache does this design mandate an explicit "commit" (seems true because of the JPA style) to change the object instance stored in the cache/ replicated? If yes this design would NOT provide an exact replacement for the POJOCache style APIs and the included flexibility. Could you clarify - did I miss something while reading the text. Thanks, Kapil
