今晩、Tomcat7 サーバーにアップデートをプッシュしましたが、正しく起動しないようです。Web ブラウザでサイトを表示しようとすると、Chrome から「リンクが壊れているようです」と表示されます。
この被害が発生する前に私がしたことは、webapps/ROOT/WEB-INF/classesフォルダー内の Java コードを更新したことだけでした。更新されたクラスはすべて、一連の Java クラスと 2 つのサーブレットでした。
最初は、WEB-INF フォルダーに間違っていると思っていましたが、web.xml確認したところ、正しいものでした (デスクトップのテスト サーバーと同じように構成されています)。
から取得したスタックトレースは次のとおりですcatalina.out。
どんな助けでも大歓迎です。この特定のエラーがどこにも見つからないようです。
