Web アプリケーションを myfaces 1.1 から 1.2 にアップグレードしようとしています。最新の 2.x バージョンに直接移行するよりも簡単だと思いました。ただし、アプリケーションを起動しようとすると、次のようなエラーが発生します。

SEVERE: StandardWrapper.Throwable
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

<web-app> タグが "2.4" から version="2.5" に更新されました。委任されたサーブレット (EvoFacesServlet) を元の javax.faces.webapp.FacesServlet に置き換えようとしましたが、成功しませんでした。

サーブレット コンテナーは Tomcat 6 です。

それを機能させるには、他に何をすべきですか？

コンテナー関連のjarをデプロイメントから削除すると、servlet-api.jar、el-api.jar、jsp-api.jarが役立ちました。それらのどれが問題の原因であったかわからない。
