我有一个EAR，Ynale.ear，其中包含一个YnaleImpl.jar和一个Ynale.war:
I have an EAR, Ynale.ear, which contains a YnaleImpl.jar and a Ynale.war:

public String value() {
return "TextValue";
}
}
Utility.jar有一个beans.xml，在启动时，WELD系统会找到它并记录日志:
The Utility.jar has a beans.xml, and on start up the WELD system finds it and logs:
WELD-000106 Bean: Managed Bean [class org.ynale.utils.TextValue] with qualifiers [@Any @Default]
在Web.war中，我具有login.xhtml，它具有:
In the Web.war I have login.xhtml which has:
#{textValue.value()}
我在日志中没有收到错误(输出到FIN/DEBUG)，但是从不调用textValue.value().我的页面上没有任何输出.
I get no errors in the log (outputting down to FIN/DEBUG) but textValue.value() is never called. I get no output on my page.
有什么想法吗?
在WAR内部定义的托管Bean可以正常工作.
Managed Beans defined inside the WAR itself work fine.
抱歉，我确实有一个，忘了包含在帖子中:
EDIT 2: Sorry, I do have one and forgot to include in the post:

推荐答案
Weld是CDI实现，它不扫描JSF 2特定的注释，而仅扫描CDI特定的注释，例如@Named.而是有一个JSF 2特定的@ManagedBean批注.为此，您需要在JAR中具有与JSF 2兼容的/META-INF/faces-config.xml，以便获取JSF 2 Web应用程序来扫描放置在/WEB-INF/lib中的JAR文件中具有JSF 2特定注释的类.
Weld, which is a CDI implementation, doesn't scan for JSF 2 specific annotations, it only scans for CDI specific annotations like @Named. You have there a JSF 2 specific @ManagedBean annotation instead. For that you need to have a JSF 2 compatible /META-INF/faces-config.xml in the JAR in order to get a JSF 2 web application to scan for classes with JSF 2 specific annotations in the JAR file which is placed in /WEB-INF/lib.
