java - Primefaces 4.0 へのアップグレード時に Tomcat 7.0.41 にアプリケーションをデプロイできない

Question

Web アプリケーションを実行すると、このメッセージが表示されます。正常にビルドされますが、展開中に、次のエラーで毎回失敗します:

SEVERE: The web application registered the JDBC driver[oracle.jdbc.OracleDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

どんな助けでも感謝します。

参考までに: 私の pom.xml は次のとおりです。

      <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-api</artifactId>
        <version>2.1.26</version>
