I've heard before WebLogic has some sort of OSGI-based kernel so it might be
that assemblies are wrapped into bundles under the hood - not sure though.

IN OSGI environment one needs to explicitly import packages containing
annotations so if OSGI were used then one'd update either a bundle or some
system configuration file with an Import-Package OSGI directive....

give a try please - simply update Catalog constructor - Catalog seem to be
instantiated by Spring just fine, and in that constructor do
getClass().getMethod("getItems").getAnnotation(Path.class); or may be in a
static initializer.
As the last resort/workaround, while you're investigating and just to keep
you going, you might want to try this feature :
http://cxf.apache.org/docs/jax-rs.html#JAX-RS-RESTfulserviceswithoutannotations
You can describe how Catalog should be treated by the JAX-RS runtime without
applying annotations and then register that description from spring
