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"

答案
我在删除扩展jar之后从我的eclipse中清理了部署。我也在WEB-INF / lib文件夹中没有验证它，
如果WebLogic Server 10.3.6.0不支持javax.faces-2.2.4 jar然后在部署期间我可能会有错误。我的控制台中的以下示例行显示它已加载2.2.4 jars。这些日志是在添加primefaces extension jar之后。

另一答案
我的问题通过不出口解决（Properties->Java Build Path->Order and Export->Uncheck primefaces and extension jar checkbox）
primefaces-4.0 jar和primefaces-extensions-1.2.0 jar。
这两个jar存在于应用程序的WEB-INF / lib文件夹中。
另一答案
在类映射中的数据包地址中通知hibernate.cfg.xml时出现此错误。如果您没有错误的地址，请记下所有配置文件。
