SearchService is a service which shares the information about Persons with the PersonService . It lets users search for individual people using simple or complex search expressions . The interaction with this service also verifies that the JAX - RS server is capable of supporting multiple root resource classes

This function uses a proxy which is capable of transforming typed invocations into proper HTTP calls which will be understood by RESTful services . This works for subresources as well . Interfaces and concrete classes can be proxified in the latter case a CGLIB runtime dependency is needed . CXF JAX - RS proxies can be configured the same way as HTTP - centric WebClients and response status and headers can also be checked . HTTP response errors can be converted into typed exceptions .
