如何在带有JSF 2.1 Mojjarra的Websphere 7.0中使用EL 2.2

Question

我已使用Websphere 7成功配置了JSF 2.1 Mojjarra和Primefaces 3.2

现在，当我尝试在XHTML页面中使用EL且该EL具有这样的参数时

#{bean.getDataList(data)}

它引发异常

任何想法，对我来说，我仍然认为它是从we​​bsphere读取EL实现的，这是真的吗？

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作为隔离的共享库，并将以下上下文参数添加到我的web.xml中，以便将那些罐子。

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

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