我正在尝试在 websphere 8.5.1 上从 jsf 1.2 升级到 jsf 2.2.2
我所做的如下：
1- put jsf-api-2.2.2.jar and jsf-impl-2.2.2.jar在我的 lib 文件夹中。
2-将 web.xml 的标头更改为如下：
<web-app
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="YourWebappID"
version="2.5">
3-更改标题面孔配置.xml如下：
<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
4-将 faces servlet 更改为如下：
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
5-将类加载器更改为 websphere 上的最后一个父类加载器，我可以在日志中看到 mojara 已成功初始化。
6-我的xhtml页面是：
<!DOCTYPE html>
<html lang="en"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head>
<title></title>
</h:head>
<h:body>
<h3>JSF 2.0 Hello World</h3>
<h:form>
<h:inputText id="sname" value="test" />
</h:form>
</h:body>
</html>
我收到以下异常：

请告知此错误，我是否必须将 javaee jar 添加到我的 lib 文件夹中？我必须在 web.xml 中添加 jsf 监听器吗？
EDIT:
通过删除 jsf-api-2.2.2.jar 和 jsf-impl-2.2.2.jar 解决了这个问题
并使用 javax.faces-2.0.10.jar 和 jboss-el-2.0.0.GA.jar，但我想让它与
jsf-api-2.2.2.jar 和 jsf-impl-2.2.2.jar，请告知如何使用最新的 mojara jar 解决上述异常。
