警告：このページでは、プレフィックス[HTML要素名]で宣言されたXML名前空間が必要ですが、その名前空間のタグライブラリは存在しません

1つのJSFページに問題があります。これはソースコードです：

この名前空間宣言を試してください

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://Java.Sun.com/jsf/html">

これを追加するだけです

xmlns = "http://www.w3.org/1999/xhtml

w3CだけでなくW3でも、非常にうまく機能します。
