現在作業中の小さなプロジェクトでエラーが発生しました。私は、Wildflyアプリケーションサーバー上で実行されているEJBプロジェクトを取得しました。このサーバーはOracle Databaseに接続されています。これはEclipseで実装したTest-Clientを介してうまく動作します。しかし、私はWebサービス経由でアプリケーションを利用できるようにしたかったのです。だから私はWebProjectを実装し、私は次のエラーを取得する別のクライアントを経由してWebProjectことを呼び出すに：

私は、javaのwsimportツールキットを介してWebApplicationClientの追加クラスを生成しました。私は問題が何であるか把握していないようです。私はすでにこの投稿をチェックしました： Can not set field to com.sun.proxy.$Proxy しかし私の場合、FacilityManagerRemoteはクラスではなくインターフェースです。私はこの事柄をさらにどのように解決するかについては考えていません。誰も助けることができますか？
