I have not found a solid solution on stackoverflow nor here yet.
I developed a Server plugin and installed it on neo4j server.
The rest works fine if it returns primitives.
However when it gets to this method:
@GET
@Path("/dum")
@Produces({MediaType.APPLICATION_JSON})
public RestResponse<Pair<String,String>> dumDum() {
return RestResponse.success("Ok", Pair.of("dum", "dum"));
}
throws this error

One solution i found was to use genson. It works BUT it breaks the
functionality of the regular neo4j endpoint db/data/. So the genson
solution ain't gonna fly.
Under a normal web app I would add this in web.xml
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
But here I do NOT have a web.xml to alter.
Please let me know my options
