json - Jersey 2 InjectLink is ignored -

i'm creating new jersey 2.21, jackson 2.6.1 rest server (i tried jersey 2.19 , jackson 2.5.3 well) , want use @injectlink provide hateoas links (like 'self') callers. basic app (taken jersey doc , jersey sample apps) isn't working, , can't figure out why.

i started taking basic widgets class from jersey doc, json or xml returned empty structure.

xml:

<widgets/> 

json:

{} 

widgets.java

package org.glassfish.jersey.examples.linking;  import java.net.uri; import java.util.list;  import javax.ws.rs.core.link; import javax.xml.bind.annotation.xmlrootelement;  import org.glassfish.jersey.linking.injectlink; import org.glassfish.jersey.linking.injectlinks;  @xmlrootelement() public class widgets {     @injectlink(resource=widgetsresource.class)     uri u;      @injectlinks({@injectlink(resource=widgetsresource.class, rel = "self")})     list<link> links;      public widgets() {} } 

i put breakpoint in resource code , examined object being returned. it.links , it.u both null. there's nothing injected.

widgetsresource.java

@path("widgets") public class widgetsresource {     @get     public widgets get() {         widgets = new widgets();         return it;     } }

web.xml:

the application object:

package org.glassfish.jersey.examples.linking;  import org.glassfish.jersey.linking.declarativelinkingfeature; import org.glassfish.jersey.server.resourceconfig;  public class server extends resourceconfig {     public server() {         packages("org.glassfish.jersey.examples.linking",             "com.fasterxml.jackson.jaxrs")         .register(declarativelinkingfeature.class);     } } 

it appears @injectlink(s) annotations being ignored. there must magic setting i'm missing, i've done jersey doc says do.

i tried both servlet 2.x (shown) , servlet 3.x (using @applicationpath) , made no difference.

some of notice package names tried more advanced, no more successful, jersey declarative linking example (https://github.com/jersey/jersey/tree/master/examples/declarative-linking). of basic fields returned, of injected links missing or null.

.../server/rest/v1/items/1 produced:

{   "id": "1",   "nextid": "2",   "previd": "0",   "prev": true,   "next": true } 

fyi - i'm running java 1.8.0_60, eclipse mars, , tomcat 8.0.26. there no errors, no warnings , no runtime messages. i'm stumped. have pointers???

i have added following servlet config:

`<init-param>         <param-name>jersey.config.server.provider.classnames</param-name>         <param-value>             org.glassfish.jersey.linking.declarativelinkingfeature         </param-value>     </init-param>' 

and links rendered in json response.
