2 questions: 1 - As per section 10.4, by default the aop bindings are global to whole VM. What happens if aop is deployed after the deployments of ear? Would all aspectized ear be instrumented? If not, can it be enfoced to do so! 2 - Should section 10.4 (below) include 'deploy-hasingleton' folder beside 'deploy' folder? anonymous wrote : 10.4. Scoping aop to the classloader | By default all deployments in JBoss are global to the whole application server. That means that any ear, sar, jar etc. that is put in the deploy directory can see the classes from any other deployed archive. Similarly, aop bindings are global to the whole virtual machine. This "global" visibility can be turned off per top-level deployment. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077111#...
