I want to be sure I have this right: You restart the servers, and access your test.jsp. You see replication. How do you know replication happens? Thereafter if you do anything else, no replication happens. Again, how do you know it doesn't happen. With SET_AND_NON_PRIMITIVE_GET, the setAttribute() call will trigger a replication. The getAttribute() call won't, as String counts as "primitive". View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964162#...
