Hi Jeff,
would something similar to the following help?
I am not sure how exactly you handle the matrix parameters, but
as i understand it is not the main issue for you, right?
Cheers,
~Jakub
@Path("/")
public class RootResource {
@Path("containers/{container_id}")
public ContainerResource getContainer(@UriParam("container_id") String containerId) {
return new ContainerResource(containerId);
}
@Path("items")
public ItemsResource getItems() {
return new ItemsResource(null);
}
}
public class ContainerResource {
String id;
public ContainerResource(String id) {
this.id = id;
}
@GET
@ProduceMime("text/plain")
public String getMe() {
return "Container(id=\"" + this.id + "\")";
}
@Path("items")
public ItemsResource getItems() {
return new ItemsResource(this);
}
}
public class ItemsResource {
ContainerResource container;
public ItemsResource(ContainerResource container) {
this.container = container;
}
@GET
@ProduceMime("text/plain")
public String getMe(@MatrixParam("ids") String ids) {
return "container: " + this.container + "items:" + ids;
}
}

One is a list of item references using a list of ids, the other by a what parent container (referenced by container_id) they are in. They both produce ItemReferencs fed into an ItemsConverter which produces the representation which is a collection/list of Item-References in XML. (Can you tell I am using CustomerDB as my basis?)

What I was trying to do is when the container resource matched the "/container/{container_id)/items" resource is forward that to the items resources with the container_id and produce a list of item references. I was and am trying to be DRY. I know I can use the same method, as one takes a list of ids and the other nothing, but I can not come up with an @UriTemplate in the items resource that works. Instead it calls the first example with an empty list.

Maybe that is not RESTful?
