Hi! The expression "within" can only be used with "call" pointcuts... it is a way of specifying the caller. Unfortunately, dynamic AOP is not working wth call expressions (but it should work with the other types of pointcut expressions): http://jira.jboss.com/jira/browse/JBAOP-433 The good news is that JBoss AOP team is already working on this issue, so expect it to be fixed in the next release. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4115951#...
