Subject CXF WS-Policy refactoring
Date Tue, 29 Jan 2008 13:23:45 GMT

CXF WS-Policy framework needs a bit of refactoring. While it's already quite sophisticated
in what it can do, and some of its features are really cool, like the ability to add JAXB
derived assertions, the ability to attach policy expressions externally and inline from Spring
using WSPolicyFeature, etc, etc, there're few things which need to be fixed a bit :
* how various policy subjects contribute to corrresponding effective policies
* how policy alternatives are selected on the server and on the client (generally a server
has to support all the alternatives while the client can select only a single one)
* automatic policy publication on the server side
* policy engine needs to be enabled by default, etc...

As such some breaking changes to interfaces like EndpointPolicy (which itself may go in the
end, with Policies just keyed by the type of policy subject), PolicyEngine, may need to be
applied. CXF does not allow for alternative PolicyEngine or EndpointPolicy implementations
be injected anyway. This should not have any adverse affect on any applications out there,
if any, which do rely on WSPolicy expressions, perhaps those dealing with WS-Addressing or
WS-RM or MTOM...
