RAD 7.5.5/WebSphere 6.1 を使用していますが、開発環境を Eclipse Juno/WAS 8.5 にアップグレードしています。RAD/WAS 6.1 ではすべてが機能しますが、Eclipse/WAS 8.5 で Web サイトをローカルで実行するのに問題があります。
作成プロセスのスクリーンキャストを撮りました。以下のリンクを参照してください。nullPointerExceptionスタック トレースも含まれます

ここに私のプロジェクト設定のいくつかの画像があります。CBSWebApp は Java/JSP アプリケーションであり、eCB はエンタープライズ アプリケーション プロジェクトです。 http://imgur.com/Ol0pDbt,mC4cT1b,WXMYvbQ#0

EclipseでnullPointerExceptionコンテキストルートを設定しようとすると、以下も表示されます。CBSWebApp動作中の RAD 環境で自分の設定を確認すると、このフィールドが「CBSWebApp」として正常に入力されていることに気付きましたが、Eclipse では空白のデフォルトのままであり、以下のエラーを生成せずに変更することはできません。
