我在 NB 中制作了项目“Java EE Web 应用程序”。
新项目 -> Java With Ant -> Java Web -> Web 应用程序。
部署后，我访问它包含的这个简单的网页 #{mainBB.number}，然后是异常原因。如果我输入像 {mBB.number} 这样的 bean 名称，则网页显示时没有数字。
这是 GF 日志消息。和 web "+ stack trace" msg 在 Firefox 上几乎是这样的。
错误信息
JSF1073: RENDER_RESPONSE 6 の処理中に java.lang.RuntimeException をキャッチしました: UIComponent の ClientId =、メッセージ =|#]
java.lang.RuntimeException:
at beans.MainBB.<init>(MainBB.java:1)
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
我认为在启动 bean 控制器或初始化此类时，el.parser 会导致一些库不匹配。
信息
库
JSF 2.3：javax.faces.jar
Java EE 7 API 库
环境
win10
(a) NG: GlassFish5.1(JavaEE8) , NB 12.0(JDK 1.8, JavaEE8)
以后想用JakartaEE9做
我试过了。
... 没变化。
・ jsf 检查（检查 import javax.enterprise.* ，检查 bean 的错字）
・ 检查源代码（@Named，@～～Scoped，setter/getter，构造函数）
・ 检查库
・ 再次阅读 jsf 2.3 网页
jsf - 识别和解决javax.el.PropertyNotFoundException：目标无法到达 - 堆栈溢出
jsf - 将 faces-config.xml 从 2.2 更改为 2.3 会导致 javax.el.PropertyNotFoundException：目标无法到达，标识符“bean”解析为 null - 代码日志
・ 追加和配置 beans.xml、faces.config-xml、web.xml
在 JSF 2.3 中激活 CDI
@FacesConfig 注释类以在 JSF 2.3 中激活 CDI
WEB-INF/beans.xml
版本="1.1" bean-discovery-mode="all"
在 WEB-INF/faces-config.xml
设置版本 2.3
web.xml
设置 javax.faces.ENABLE_CDI_RESOLVER_CHAIN 为真
在源
集@FacesConfig 2.3
・ 添加 jsf 库、cdi(1.2, 2.0) 库、java el 库
・ 其他版本
NG: (a) + GF6.0m1, (a) + wildfly 20.0.1 final, (a) + Payara ml 5.2020.4
OK: (b) GlassFish4.1(JavaEE8) , NB 8.2(JDK 1.7, JavaEE7)

package beans;
