如何摆脱 org.restlet.ext.jaxrs.internal.util.ExceptionHandler MessageBodyWriter？

Question

我可以打电话http://localhost/products and get the desired XML output. If I call http://localhost/facets我得到

Mar 24, 2015 3:10:50 PM org.restlet.ext.jaxrs.internal.util.ExceptionHandler noMessageBodyWriter
WARNING: No message body writer found for class com.galexis.search.productsearch.bean.facet.FacetsDTO(generic type is class com.galexis.search.productsearch.bean.facet.FacetsDTO); response media type should be: application/xml; accepted media types are: [[text/html, application/xhtml+xml], [application/xml], [*/*]]

这是我的资源：

public class MyResource {

    @Path("products")
    @GET
    @Produces("application/xml")
    public ProductsDTO getProductsByFieldNamesAndSearchStrings(somme parameters) {

        return getProducts();
    }

    @Path("facets")
    @GET
    @Produces("application/xml")
    public FacetsDTO getProductsFacetByFieldNamesAndSearchStrings(somme parameters) {
        return getFacets();
    }

}

产品DTO

@XmlRootElement(name = "products")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType
public class ProductsDTO {
   ...
}

FacetsDTO

@XmlType
@XmlAccessorType(XmlAccessType.FIELD)
public class FacetsDTO {
   ...
}

知道缺少什么吗？

经过艰难的探索和调试 restelt jax-rs 扩展后，我发现它会检查 @XmlRootElement 元素。如果它不存在，它拒绝服务器 application/xml 答案。
