JSF 2.3 - Cannot invoke "javax.faces.context.FacesContext.getAttributes()" because "this.context" is null

 原文  2022-07-06 10:27:59  3   1    java/ jsf-2.2/ spring-tool-suite

Question

The problem is when execute the lines with jsf tags in the jsp file. I execute a normal jsp file and works. Before the error was "Cannot find the Faces Context", but I update the jar of jsf-impl and jsf-api to the last version, and then give me this error. I look for error and the problem should be with the URL pattern matches request URL but matches. This is the error:

6: -->
7: <jsp:root version="2.1" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:webuijsf="http://www.sun.com/webui/webuijsf">
8:     <jsp:directive.page contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"/>
9:     <f:view>
10:         <webuijsf:page id="page1">
11:             <webuijsf:html id="html1">
