Apache MyFaces Trinidad 1.2 throws NullPointerException with Tomcat 8.5

528 views Asked by At

I created a JSF 1.2 project in eclipse and deployed on Tomcat 8.5 but it throws NullPointerException when I open the jsp page in a browser.

The application works fine in Tomcat 6. I am using JSF 1.2 and Apache MyFaces Trinidad 1.2

The following is jsp page

        <?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>

The following is the exception in console of eclipse

SEVERE: Servlet.service() for servlet [jsp] threw exception

I had the same problem at about 2 years ago. The productive Webserver has been changed from Tomcat7 to Tomcat8 and Trinidad was no longer working. I moved the whole Project to jsf 2.2 and trinidad 2.1.1, of which a user solved the Tomcat 8 Problem. It is two years ago, but as far as I know the trinidad community is dead somehow...
