当尝试运行JSF 2.3应用程序时，我在浏览器窗口上得到以下消息"发生错误"和以下堆栈跟踪。

我正在使用以下内容：
- JSF 2.3
- Payara服务器5.194
- JDK 8
- Java EE 7
- IDE：运行在Java 14上的Apache Netbeans 11.3
在我的情况下，我遇到了同样的问题，我已经将我的wildfly版本从20.10更改为26.1
我遇到过类似设置的问题，原因是CDI的bean.xml文件不正确。更新后的文件如下-
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_2_0.xsd"
bean-discovery-mode="all" version = "2.0">
</beans>
而较旧的文件如下
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
bean-discovery-mode="annotated" version = "1.0">
</beans>
如果定义版本，则必须将bean-discovery-mode设置为all
这是带解释的链接-CDI行为
还可以阅读下面关于CDI应用程序包的链接，了解有关隐式和显式CDI归档的信息。
