如何使用JSF 2.1 Mojjarra

Question

使用EL 2.2和WebSphere 7.0我成功配置JSF 2.1 Mojjarra和Primefaces 3.2和WebSphere 7

現在，當我嘗試在我的XHTML頁面中使用EL這EL有這樣

參數

#{bean.getDataList(data)} 

拋出異常

什麼想法，對我來說我認爲還是讀取從WebSphere它自我EL實現是真的嗎？

Answer 1

我解決了它，首先我使用EL-api.2.2.jar，El-impl.2.2.jar和juli-6.0.14.jar作爲獨立的共享庫，並將下面的上下文參數添加到我的web.xml中爲了在這些罐子裏上課。

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

現在亞姆運行EL2.2在我的WebSphere 7在默認情況下運行EL2.1
