私は Apple で働いており、データ サービス機能を備えた WSO2 ESB を使用してプロトタイプに取り組んでいます。DSS機能を備えたWSO2 ESB 4.0.3を使用しています。データ サービスをデプロイし、ESB のプロキシ サービスからデータ サービスを呼び出しました。MAC OS X 10.7.4を使用しており、Java バージョンの詳細は以下のとおりです。
Java バージョン "1.6.0_31" Java(TM) SE ランタイム環境 (ビルド 1.6.0_31-b04-415-11M3635) Java HotSpot(TM) 64 ビット サーバー VM (ビルド 20.6-b01-415、混合モード)
私の DS サービスは、パラメーター A などの特定のパラメーターを予期していますが、入力 XML でこのパラメーターを渡しません。WSO2 ESB コンソールで次のエラーが表示されます。

SOAP 障害を見ると、エラー メッセージをクライアントに返さなければなりませんが、正しいエラー メッセージは "Parameter Missing" でなければならないと考えていました。SOAP 障害の理由テキストは " javax.xml.stream.XMLStreamException"です。
私がやっていることは間違っていますか、それとも DSS のバグですか?
