Hi This is a good news... Here's some more information on how to apply this feature. I'll need to document it better - have added a task item...For, given the Catalog class mentioned in this thread the following model can be created :
<model> <resource name=" com.att.ecom.catalog.Catalog" path="/catalog"> <operation name="getItems" verb="GET" path="/items"/> </resource> </model> The schema for 'model' is here : http://svn.apache.org/repos/asf/cxf/trunk/rt/frontend/jaxrs/src/main/resources/schemas/jaxrs.xsd it is limiting a bit, specifically, parameter types should be capitalized at the moment and there's no a proper enum definition for parameter types. For ex, 'PATH', 'QUERY', 'MATRIX', 'HEADER' is what should be used when describing parameters that would otherwise be annotated with @PathParam, @QueryParam, @MatrixParam, @HeaderParam. There's no need to describe input parameters which are mapped to request bodies. Response parameters are not described too. 'resource' represents a resource class. It can describe either a root resource or a subresource one. For ex, if you have @Path("catalog") public class Catalog { @GET @Path("items") public List<Item> getItems() {...} @Path("items/{id}") public Item getItemName(@PathParam("id") Long id) {...} } where getItemName is a subresource locator and Item class has a method like public class Item { @GET public String getName() {...} } then, if we remove annotations, the same can be described like this : <model> <resource name=" com.att.ecom.catalog.Catalog" path="/catalog"> <operation name="getItems" verb="GET" path="/items"/> <operation name="getItemName" path="/item/{id}"> </operation> </operation> </resource> <resource name="com.att.ecom.catalog.Item"> <operation name="getName" verb="GET"/> </operation> </resource> </model> The resource with name "com.att.ecom.catalog.Item" is recognized as a subresource because when it introspects com.att.ecom.catalog.Catalog#getItemName it finds that its return type's name matches '"com.att.ecom.catalog.Item". So it's a flat structure but perhaps I'll support embedding resources too, similar to the way it's done in WADL. At the moment the only place where this feature is demoed is in a 'greeter_rest' demo in a DOSGi distribution[1] where IMHO this feature can be very handy indeed but I do want to allocate more time on it and document and enhance it properly.
