GAE で Spring MVC を使用してアプリケーションを作成しようとしています。XMLに応答する必要があり、JAXBを使用してそれを行います。応答オブジェクトは複雑 (インターフェースを含む) ですが、ローカルではすべて正常に動作します。問題は、App Engine にデプロイするときです。私の要求の応答は、この例外をスローします (複雑なオブジェクト、単純なオブジェクトが正常に動作する場合):

編集: 応答の構造を追加します...戦略パターンを実行しようとしています。

MyRequestController.java

@Controller
@RequestMapping("/.myrequestX")
public class MyRequestController 
{

    @Autowired
    private GenericResponse response;

    @Autowired
    private X_ResponseBehaviorImpl valorDTO;

    @RequestMapping(method = RequestMethod.GET)
    @ResponseBody
    public Object getRespuesta(ModelMap model, HttpServletRequest req)
    {  
      // Other parts of code...


      response.getResponseBehavior().setResponse(valorDTO);
      return response;
    }

}

GenericResponse.java

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso({ X_ResponseBehaviorImpl.class, Y_ResponseBehaviorImpl.class})
public class GenericResponse
{

    @XmlElement
    private String id;

    @XmlElement
    private ResponseBehavior responseBehavior;

    public String getId() {
    return id;
    }

    public void setId(String id) {
    this.id = id;
    }

    public ResponseBehavior getResponseBehavior() {
    return responseBehavior;
    }

    public void setResponseBehavior (ResponseBehavior responseBehavior) {
    this.responseBehavior = responseBehavior;
    }
}

ResponseBehavior.java

import com.sun.xml.internal.bind.AnyTypeAdapter;

@XmlRootElement
@XmlJavaTypeAdapter(AnyTypeAdapter.class)
public interface ResponseBehavior 
{
    void setResponse(Object value); 
}

X_ResponseBehaviorImpl.java

public class X_ResponseBehaviorImpl implements ResponseBehavior
{

 @XmlElement
 String comb10;

 @XmlElement
 String reint4;

 private void setResponse(Object value)
 {
   X_ValueDTO x_value = (X_ValueDTO) value;

   this.comb10 = x_value.getCombinacion();
   this.reint4 = x_value.getReintegro();
 }


   public void setComb10(String comb10) {
   this.comb10 = comb10;
 }


    public void setReint4(String reint4) {
    this.reint4 = reint4;
 }


}

Java6にはJAXBが含まれています..いくつかのバージョン（JDK6_u04、JDK6_u14 ...）で試してみましたが、問題は解決しません...

前もって感謝します！！！

Java 6 には JAXB が含まれている可能性がありますが、GAE の JVM 環境で利用できるかどうかはわかりません。アプリと一緒に JAXB jar をパッケージ化することをお勧めします。Rhino jar (スクリプト サポート用) が GAE 運用環境で利用できないという同様の問題がありました。

それが役立つことを願っています。
