我已将我的应用程序从 faces 2.1 升级到 2.2。当我在浏览器中访问我的应用程序时出现以下错误。在我的使用 javax.faces-2.2.4 jar、primefaces-4.0 jar 和 primefaces-extensions-1.2.0 jar应用

这是我的 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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-app_2_5.xsd">

这是我的 faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xi="http://www.w3.org/2001/XInclude" 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">

我的问题通过不导出 ( Properties->Java Build Path->Order and Export->Uncheck primefaces and extension jar checkbox)得到解决

primefaces-4.0 jar和primefaces-extensions-1.2.0 jar。

这两个 jar 文件存在于应用程序的 WEB-INF/lib 文件夹中。

这个错误是在类映射中的数据包地址通知hibernate.cfg.xml时出现的。如果您没有错误的地址，请记下所有配置文件。
