Answer 1

エラーは、アプリケーションサーバのTomcatはJSPをコンパイルすることができないと述べています。 JSPはURLでリクエストするとコンパイルされます。

ディスパッチャの結果が実行されると、StrutsはJSPページに間接的に転送します。

通常、このエラー500（内部サーバーエラー）は、JSPコードにエラーがある場合に発生します。しかし、メッセージ

方法getJspApplicationContext(ServletContext)は タイプJspFactoryのために定義されていません。

には、クラスパスに互換性のないバージョンのJspFactoryがあると記載されています。

解決方法は、正しいバージョンのライブラリでクラスパスを修正することです。アプリとともにTomcatにサーブレットライブラリをデプロイすると、しばしば起こります。 Tomcatは既にweb.xmlで定義されているWebアプリケーションのバージョンを満たすためにdeployでロードされるサーブレットの実装をすでに持っているので、これは起こりません。

Answer 2

これは、jarファイルを適切な場所に配置する際に発生する可能性のあるエラーです。
