JSF a4j 出错 +战斧 + myfaces：资源框架未初始化，请检查 web.xml 中的过滤器配置

Question

我试图在 JSP 中使用 ，但出现以下我根本不理解的错误：

Exception while calling encodeBegin on component : { Component-Path :
  [Class: org.ajax4jsf.framework.ajax.AjaxViewRoot,ViewId: /pages/clienteAM.jsp]
  [Class: javax.faces.component.html.HtmlForm,Id: clientesForm]
  [Class: javax.faces.component.html.HtmlDataTable,Id: cityList]
  [Class: javax.faces.component.UIColumn,Id: j_id88]
  [Class: javax.faces.component.html.HtmlDataTable,Id: telefonos]
  [Class: javax.faces.component.UIColumn,Id: j_id89]
  [Class: org.ajax4jsf.ajax.html.HtmlAjaxCommandLink,Id: j_id91]
}

Caused by: javax.faces.FacesException: 
Resources framework is not initialised, check web.xml for Filter configuration

我的 web.xml 看起来像这样:

<?xml version="1.0"?>

摘自 RichFaces 文档：

不同的情况下会出现一些问题
web.xml 文件中定义的过滤器
冲突。为了避免这些问题，
RichFaces 过滤器必须是第一个
web.xml 中的其他过滤器
配置文件。

尝试更改您的 web.xml 文件，以便您的 RichFaces 过滤器（又名 Ajax4Jsf）位于您的 extensionsFilter 之前。
