私は次のコードを持っているGoogle App Engineと使用しようとします:Jaxb2Marshaller

@Entity
@XmlRootElement
public class Incident {
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Key incidentId;

@XmlJavaTypeAdapter特定のアダプターで注釈を使用するか@XMLTransiet、単にこのフィールドをスキップしようとしましたが、まだ次のエラー メッセージが表示されます。どうすればこれを解決できますか?

appengine-api-1.0-sdk-1.7.3.jarをjaxbクラスパスに追加することで、なんとか動作させることができました。面白い *.jar が機能しなかったので、完全な .jar を指定する必要がありました

以下をクラスパス引数に追加します

;appengine-api-1.0-sdk-1.7.3.jar

私のコマンド引数は次のとおりです。

wsgen -cp "./war/WEB-INF/classes;PATH_TO_YOUR_JAR/appengine-api-1.0-sdk-1.7.3.jar" -wsdl -keep -r "./war" -d "./war/WEB-INF/classes" -s "./src"  com.example

正しいjar名を指定していることを確認してください。私の場合はappengine-api-1.0-sdk-1.7.3.jar

乾杯ババジデ
