Eclipse で新しい Web サービス (ボトムアップ、apache axis 1、tomcat 6) を作成しようとしていますが、試行する前に警告が表示され、その後エラーが発生します。

エラー：

IWAB0398E Error in generating WSDL from Java:  java.lang.ClassCastException: org.apache.axis.encoding.ser.BeanSerializer cannot be cast to org.apache.axis.encoding.Serializer

ここで私は Serializable を使用します:

public class IntegrationUtils extends Utilities implements java.io.Serializable {
    private static final long serialVersionUID = 7515033201857603982L;

警告の概要:多くの警告は、Web サービス クラスで使用されるクラスにデフォルトのコンストラクター がないことに関係しています。

警告は次のとおりです。

同じクラスファイルを含む JAR または JAR ファイルが重複している場合は常に、ClassCastException が発生します。あなたの場合、それは別の Axis バージョンでもある可能性があります。この問題は通常、Tomcat が軸クラスをインスタンス化し、このインスタンスをアプリケーションに送信するときに発生します。反対側のアプリケーションは、独自の jar を使用できます (WAR または EAR にパッケージ化されています)。また、Web または Java EE コンテナーで複数のクラスローダー階層を使用できる可能性があるため、同じサーバーで同時に独自の jar ファイル バージョンを使用してさまざまな Web アプリケーションを実行できます。

しかし、それを解決する方法は？Tomcat と Web アプリケーションのすべての jar でこれらのクラス (StackTrace に表示) を検索し、Axis-Requests/-responses のインスタンス化に使用されているクラスを確認します。最も簡単な解決策は、Web アプリケーションから関連する jar を削除し、ランタイム環境 (Tomcat) の jar に対してコードをコンパイルすることです。tomcat-jar-versions が使用できない場合は、server-jars にパッチを適用してみてください。代替ソリューションは、クラスローダーを制御するための Web アプリケーション/サーバーの別の構成です。
