Simon, In terms of your question I mean the latter - to invoke the computed policies from a custom BindingInvoker (if the runtime isn't going to set up an interceptor to do it for me). But I was under the impression that the PolicySetAttachPoint.getPolicySets() API related only to the model, and that the result of computation/resolution was stored somewhere else - hence my question. Are you saying that the process of policy computation actually updates the policy sets attached to e.g. a Binding? If so, then there is no problem - my binding invoker can clearly get them at invocation time. But I find that surprising.

If the latter then you should be able to get at the resolved policy information using the binding object in question, for example, the SCA binding is defined as follows public class SCABindingImpl implements SCABinding, Extensible, PolicySetAttachPoint, OptimizableBinding { ... public List<PolicySet> getPolicySets() { return policySets; } ... } Once the model has gone through the composite build phase you can get the computed policysets for a binding directly. If the former then there is currently no API to get at information in the underlying model from the component implementation. > > > For implementation policies, I observe that the runtime sets up a > PolicyHandlingInterceptor in the invoker chain, which invokes relevant > PolicyHandlers (e.g. the JaasAuthenticationPolicyHandler) before and > after.

It's also not clear in my mind what dictates which policies can be applied where. I'm assuming someone is going to jump in here and share that information but I'll dig into it too as I'm interested to know the ins and outs of this. > > > Any pointers would be much appreciated. > > > > Many thanks > > Steve Chamberlain > > > > > > > > > > This message and the information contained herein is proprietary and > confidential and subject to the Amdocs policy statement, > you may review at http://www.amdocs.com/email_disclaimer.asp This message and the information contained herein is proprietary and confidential and subject to the Amdocs policy statement, you may review at http://www.amdocs.com/email_disclaimer.asp --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
