caching - ResourceHttpRequestHandler が間違った (キャッシュされた?) リソースを返す

Question

jQuery Mobile フロントエンドに静的リソースを提供する Spring (3.2.2) バックエンドがあります。リソースはマップ /webapp/resources/images の下にあります。このマップに既に存在するリソースは正しく返されますが、新しいリソースを追加して (ブラウザを使用して) アクセスしようとすると、404 not found が表示されます。マップから既存のリソースを削除しても、リクエストに応じてまだ見つかります。これはキャッシングの問題だと思いますか？

リソースを更新するたびに、Eclipse Juno SR2 で実行されている apache-tomcat-7.0.32 をリロード (停止/開始) します。また、運が悪くてもEclipseをシャットダウンして再起動しようとしました。

推測させてください...アプリケーションの起動後src/main/resources/にディレクトリの内容を変更していますか? を使用するため、ソースフォルダーの変更は実行中のアプリケーションには表示されません。フォルダーはクラスパスにもありません。ディレクトリで手順を繰り返すことにより、この理論をテストできます。target/classes/src/target/

これが問題の原因でない場合は、ビルドツール (Maven?) とサーブレットコンテナー (Tomcat? Jetty? スタンドアロン? 埋め込み?) に関する情報を追加すると役立ちます。
