私は、私のような問題を抱えている人といくつかの投稿を読んだことがあります。ServiceMix JAX-RS - ResourceConfigインスタンスにルートリソースクラスが含まれていません
まず、私は...
https://vzurczak.wordpress.com/2014/09/30/web-applications-with-osgi-working-with-jersey/
しかし、私はServiceMixのではなく、Karafを使用していますが、このチュートリアルを次しています。でも十分に似ているはずです。
私のpom.xmlはこのようになります...

トリビアル実装はこれです：

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
/**

public class MyRestResource {
@GET
public Response getDataToDisplay() {
return Response.ok().entity("Yes, it works.").build();
}
}
