Hi,
I'm try to create a new policy. but I get an exception when using
'requires' in the composite file (see 'webservice.composite' - line 8a),
but not when using 'policySets' (line 8b). The node is started with the
command: node = TuscanyRuntime.runComposite(composite, "target/classes");
1) Why is it not finding the policySet defined in the definitions file?
Also, I'm having difficulty in understanding how the various classes
(policy, processor, provider, interceptor, builder, and factories) interact
with each other and with the tuscany runtime.
2) Is there an overview of the policy lifecycle in Tuscany SCA 2.0?
Cheers,
Nick May.
