java - 如何将 EL 2.2 与 Websphere 7.0 和 JSF 2.1 Mojjarra 结合使用

Question

我使用 websphere 7 成功配置了 JSF 2.1 Mojjarra 和 Primefaces 3.2

现在当我尝试在我的 XHTML 页面中使用 EL 时，这个 EL 具有这样的参数

#{bean.getDataList(data)}

它抛出异常

 javax.servlet.ServletException: /bean/beanView.xhtml @52,213 actionListener="#{bean.getDataList(data)}" Error Parsing: #{bean.getDataList(data)}

任何想法，对我来说，我认为它仍然从 websphere 读取 EL 实现，它本身是真的吗？

Answer 1

我解决了这个问题，首先我使用 EL-api.2.2.jar 、 El-impl.2.2.jar 和 juli-6.0.14.jar 作为独立的共享库，并将以下上下文参数添加到我的 web.xml 中，以便这些 jar 中的类。

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

现在我在我的 websphere 7 中运行 EL2.2，默认情况下运行 EL2.1
