In the 2.2 release, J2EE agents provide a composite advice feature. This feature allows the policy and authentication services of Access Manager to decouple the advice handling mechanism of the agents. This allows you to introduce and manage custom advices by solely writing Access Manager side plug-ins. Starting with this release, you are not required to make changes on the agent side. Such advices are honored automatically by the composite advice handling mechanism.
Benefit - Composite Advice: A benefit of composite advice is that you can incorporate a custom advice type without having to make changes to an agent deployment.
