我在eclipse中创建了一个JSF1.2项目，并部署在Tomcat8.5上，但是当我在浏览器中打开jsp页面时，它抛出了NullPointerException。

这个应用程序在Tomcat6中运行得很好。我使用的是JSF1.2和ApacheJSF12.2和ApacheMDARDI1.2，我使用的是MyFaces

以下是jsp页面

代码语言：javascript
复制
        <?xml version="1.0" encoding="UTF-8" ?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:trh="http://myfaces.apache.org/trinidad/html"
    xmlns:tr="http://myfaces.apache.org/trinidad"
     version="1.2">
    <jsp:directive.page language="java"
        contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" />
    <jsp:text>
        <![CDATA[ <?xml version="1.0" encoding="UTF-8" ?> ]]>
    </jsp:text>
    <jsp:text>
        <![CDATA[ <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> ]]>
    </jsp:text>
    <html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Test</title>
</head>
<body>
    <f:view>
    <tr:outputText value="test jsf"></tr:outputText>        
    </f:view>
</body>
    </html>
</jsp:root>

以下是eclipse控制台中的例外情况

大约两年前，我也遇到过同样的问题。生产was服务器已从Tomcat7更改为Tomcat8，而且千里达不再工作。我将整个项目迁移到了jsf 2.2和千里达2.1.1，其中一个用户解决了Tomcat8问题。那是两年前的事了，但据我所知，千里达社区不知何故已经死亡了。
