この問題はSeamに関連しています。私はSeamをしませんが、Tomcat 6ではうまくいきません。いくつかの[Googleの結果]（http://www.google.com/search?q=java.lang.NullPointerException+at + org.jboss.seam.jsf.SeamViewHandler.calculateLocale）これを確認します。これはSeamに関係しないので少なくとも私の記事に関連していません。 – BalusC

シームフレームワークの1つの小さなjarファイルがプロジェクトから削除されずに残っていることが判明し、このエラーが発生しました。そしてbtw。あなたのチュートリアルは素晴らしいBalusCです：> –

シームプロジェクトの手紙に@BalusCのチュートリアルに従わないことに注意してください。チュートリアルは悪いと言っているわけではありませんが、それは縫い目を過度に網羅しています。代わりにシームの文書を使用してください。 –

これは、ロケール設定を探しているように見える - あなたはあなたの設定ファイルで設定1を持っているか、そしてそのためのロケールは、あなたの中に存在しない場合アプリ？

私はこの同じエラーを持って、問題は私がSeamリスナーを活性化するためのweb.xmlに数行を忘れてしまったことを、実際にあったが見つかりました：

<listener> 
    <listener-class>org.jboss.seam.servlet.SeamListener</listener-class> 
</listener>

これはので、多分、この答えは簡単にでき、再現誤差のようなにおい解決策を探している不幸な人々のための解決策になります。 （OTOH、NullPointerExceptionのように、それは起こる他の多くの理由があるかもしれません、私が見る限りスタックトレースでは説明されていません）。
