私の Web アプリケーションは、Facelets と RF3.3 なしで JSF(2.0) を実行しています。Trinidad を既存の Web アプリケーション プロジェクトに統合する必要があります。
trinidad jar をダウンロードし、WEB-INF/lib フォルダー内に配置しました。しかし、トリニダードの構成ガイドを調べたところ、web.xml に複数のエントリを追加する必要があることがわかりました。trinidad-config.xml ファイルも作成する必要があります。
web.xml、特にサーブレットで変更を行うと、アプリケーションが応答しなくなるのではないかと心配しているため、完全に迷っています。
FaceletsなしでTrinidad + RF3.3をJSF(2.0)に統合する方法を教えてください。
WEB-INF/lib に jar を追加し、web.xml と faces-config.xml にエントリを作成してアプリケーションを起動すると、次のエラーが発生しました。
