問題

JSFアプリケーションは、次の開発環境を使用して、ローカルGAE環境にデプロイできます。

JSF 2.1.7
Google App Engine SDK 1.6.3

しかし、GAEプロダクション環境に配備されている間にエラーメッセージが表示されます。

以下は、GAEから記録されたエラーメッセージです。

com.sun.faces.config.ConfigureListener installExpressionFactory: Unable to instantiate ExpressionFactory 'com.sun.el.ExpressionFactoryImpl'
E 2012-04-24 03:37:37.989
com.sun.faces.config.ConfigureListener contextInitialized: Critical error during deployment:
com.sun.faces.config.ConfigurationException:
    It appears the JSP version of the container is older than 2.1 and unable to locate the EL RI expression factory,
    com.sun.el.ExpressionFactoryImpl.  If not using JSP or the EL RI, make sure the context initialization parameter,
    com.sun.faces.expressionFactory, is properly set.
