我在特立尼达使用MyFaces。以下SEVERE消息一直在启动：
SEVERE: Both MyFaces and the RI are on your classpath.
Please make sure to use only one of the two JSF-implementations.
我的glassfish-web.xml中有以下内容：
<glassfish-web-app error-url="">
<class-loader delegate="false"/>
<property name="useMyFaces" value="true"/>
</glassfish-web-app>
以下类路径中的JAR：
