Here is what I am looking for, excerpt from AOP_Middleware_JBoss ppt: "Aspects can resolve metadata dynamically The AOP Invocation object (ThisJoinPoint) gives hooks for this. Metadata can be attached to a invocation and propagated Aspects can pass information to one another locally or remotely Metadata can be overridden on a per Thread basis Change behavior per Thread Provide simple mechanism to clear all Thread metadata (Thread Pooling) Default values can be defined/managed per VM or per Cluster" Can somebody tell me how to implement it, or a link toward that? Thx. Mike View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074450#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
