JSF-带有参数的调用方法(tomcat6) [英] JSF - call method with parameter (tomcat6)

问题描述

我正在尝试在tomcat6上运行我的项目(通常在tomcat7上运行).但是JSF现在无法调用带有参数的方法，例如

I'm trying to run my project (normally working on tomcat7) on tomcat6. But JSF can't call methods with parameters now, e.g.

<h:commandLink action="#{bean.setpage('index')}"/>

它在Tomcat7上正常工作.

It works normally on Tomcat7..

是否可以在tomcat6上调用带有参数的方法?

Is it possible to call method with parameter on tomcat6?

更新:以下两个答案都是正确的，而且我还必须更新 context.xml :

UPDATE: both answers bellow are correct, and i also had to update context.xml:

<context-param>
    <param-name>org.apache.myfaces.EXPRESSION_FACTORY</param-name>
    <param-value>com.sun.el.ExpressionFactoryImpl</param-value>
</context-param>
<context-param>
    <param-name>com.sun.faces.expressionFactory</param-name>
    <param-value>com.sun.el.ExpressionFactoryImpl</param-value>
</context-param>

推荐答案

如果使用的容器完全支持JSF 2.0，则可以直接进行

If you are using a container which supports JSF 2.0 completely, you can directly do

<h:commandLink action="#{bean.setpage('index')}"/>.

否则，您必须使用f:param或f:attribute.我认为Tomcat 7完全支持jsf 2，但是Tomcat 6不支持开箱即用.因此，您必须添加jstl-api-1.2.jar，jstl-impl-1.2.jar和el-impl-2.2.jar库才能使其在Tomcat 6上运行.

Else you have to use f:param or f:attribute. I think Tomcat 7 supports jsf 2 completely but Tomcat 6 does not support out of the box. So you have to add jstl-api-1.2.jar, jstl-impl-1.2.jar and el-impl-2.2.jar libraries to make it work on Tomcat 6.
