I think JacksonFeature is actually
registering org.codehaus.jackson.jaxrs.JacksonJaxbJsonProvider.
As for ClientConfig vs Client - You can store the config somewhere and
reuse it later, it depends on how often do You create the client or hoe
often Your configuration changes etc., so as long as it works for You -
then I guess it's fine :)
@Tony
It's located in javax.annotation:javax.annotation-api
below is a short fragment of my project dependencies which specify this JAR
+--- org.glassfish.jersey.core:jersey-common:2.0+ -> 2.0-rc1
| +--- javax.ws.rs:javax.ws.rs-api:2.0-rc3
| | \--- javax.annotation:javax.annotation-api:1.2-b02
It is indirectly required by Jersey, So I guess, You might be using wrong
Jersey version ?
Annotation itself is specified in JSR 250: Common Annotations for the
JavaTM Platform, Maintenance Release 2 (
http://jcp.org/aboutJava/communityprocess/maintenance/jsr250/jsr250changelog_2.html)
which is still a draft
