Thanks for the explanation - I do see the content within the jboss-aop.xml file, so this should be functional. 'myObject' is a contrived example for illustration - in fact, we are using code based upon the sample PojoCache which uses the Student, Person, Course, etc. Without the remove(), the replication does not occur. It must have a remove then a putObject. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977697#...
