You can use UriBuilder.fromresource(), but this only works if the supplied Resource class is a root resource (this is clearly mentioned in the javadocs). I found a way to achieve this even if you are in a sub-resource class:

@POST
@Consumes({MediaType.APPLICATION-XML, MediaType.APPLICATION-JSON})
public Response createUser(final User user, @Context UriInfo uriInfo) {
    // persist the user here
    URI uri = uriInfo.getAbsolutePathBuilder().path(user.getId()).build();
    return Response.created(uri).build();
}
