无法使用 JBoss EAP 6.2 定位 EL RI 表达式工厂

Question

我正在使用Jboss EAP 6.1、Eclipse Kepler、Maven（嵌入在 Eclipse 中的版本）。 然后应用程序启动，我有这个错误：

            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.

这是 pom.xml：

我还包含了 Jboss EAP 的运行时库，但它不起作用。

你能帮帮我吗？谢谢

我已经解决了这个问题，我从 web.xml 中删除了以下contex-param：

<context-param>
    <param-name>com.sun.faces.expressionFactory</param-name>
    <param-value>com.sun.el.ExpressionFactoryImpl</param-value>
</context-param>
