プロジェクトがコンプ用ではなく構成されている可能性があります。 .classpathおよび.projectを削除して、既存のソースからプロジェクトを再作成してください。また、ドットで始まる.settingsなど、SVNに誤ってコミットされている場合は、Eclipse内部ディレクトリを削除します。

ノードを追加する

<fixed facet="jst.web"/>

問題が解決する場合があります。プロジェクトを閉じてから再度開くか、プロジェクトをEclipseから（コンテンツを削除せずに）削除してから、File/OpenProjectFromFilesystemをリロードする必要があります。
