我使用Java 8，glassfish 5 build 25，Eclipse。我正在尝试从Java EE 7升级到Java EE 8.所以我从这个简单的例子开始。

CDI Bean：
@Named
@ViewScoped
public class CommentFront implements Serializable {
private static final long serialVersionUID = 1L;
public void addComment() {
System.out.println("I don’t work: ");
}
}
简单的JSF页面comment.xhtml
<!DOCTYPE html >
<html lang="en"
xmlns="http://www.w3.org/1999/xhtml"

<h:body>
<h:form id="form">
<h:commandButton id="OneBtn" value="1 Comment" action="#{commentFront.addComment()}" >
</h:commandButton>
</h:form>
</h:body>
</h:head>
</html>
错误：
javax.el.PropertyNotFoundException: /comment.xhtml @17,89 action="#{commentFront.addComment()}": Target Unreachable, identifier 'commentFront' resolved to null
当我第一次开始glassfish它打印：

为什么像这样简单的东西不适用于glassfish 5 ????
解决方案1：
import javax.enterprise.context.ApplicationScoped;
import javax.faces.annotation.FacesConfig;
@ApplicationScoped
@FacesConfig(version = FacesConfig.Version.JSF_2_3)
public class JSFActivator {
}
现在一切正常。
解决方案2：
切换到Payara 5.183，它开箱即用。无需解决方案1
意见：为什么地狱玻璃鱼这个坏了。令人遗憾的是，Java EE 8的参考实现应用程序服务器在如此简单的工作中失败了。我希望这个chane现在已经从Oracle转向Eclipse。
我想我会切换到Payara，直到glassfish被修复。
