我有一些基于 JSF 和 CDI 的 Web 应用程序，它在 Websphere ND 8.5 中完美运行。然而，它在 Liberty Profile 16 (WebSphere Application Server 16.0.0.3/wlp-1.0.14) 中不起作用。如果我尝试启动已部署 war 的 Liberty Profile，则会导致
com.ibm.ws.container.service.state.StateChangeException: org.jboss.weld.exceptions.IllegalArgumentException: WELD-001301: Annotation @javax.inject.Named(value=oam_FLOW_BUILDER_FACTORY_BEAN_NAME) is not a qualifier
当我尝试从其中之一开始时，错误是相同的
<webApplication id="myWebApp" location="myWebApp.war" name="myWebApp">
<classloader delegation="parentFirst"/>
</webApplication>
或
<webApplication id="myWebApp" location="myWebApp.war" name="myWebApp">
<classloader delegation="parentLast"/>
</webApplication>
我正在使用这些功能:
<featureManager>
<feature>webProfile-7.0</feature>
<feature>localConnector-1.0</feature>
<feature>cdi-1.2</feature>
<feature>servlet-3.1</feature>
</featureManager>
如果我在没有 myWebApp 的情况下启动 Liberty Profile，然后尝试通过 Eclipse 添加 Web 应用程序，则会得到

我听到有人说这是因为反射(CDI 依赖的某些功能)在 Liberty Profile 中不起作用，但在 WAS ND 中起作用。老实说，我认为这不是最终的解释。我倾向于相信这是我所缺少的与类加载器相关的一些技巧。
整个库列表是:
"wsdl4j.jar" "all-themes-1.0.10.jar" "axis.jar" "check-sessionid.jar" "commons-discovery-0.2.jar" "commons-logging.jar" "javax.faces-2.2.8.jar" "javax.servlet_3.0.0.jar" "javax-inject.jar" "jaxrpc.jar" "joda-time-2.9.4.jar" "jsf-api-2.2.8.jar" "jsf-impl-2.2.8.jar" "log4j-1.2.17.jar" "log4j-boot.jar" "lombok.jar" "ojdbc6.jar" "primefaces-5.1.RC1.jar" "primefaces-5.1.RC1-sources.jar" "saaj.jar"
在 WebSphere ND 8.5 中，我使用这些设置成功启动了相同的 Web 应用程序:
1 - 服务器特定的应用程序设置:类加载器策略
2 - 类加载器顺序:首先使用父类加载器加载类
3 - WAR 类加载器策略:应用程序中每个 WAR 文件的类加载器
4 - 共享库:
cells:hohmlweb01-aixCell01:nodes:hohmlweb01-aixNode01:servers:Sistemas_MyCompany_HML
Cell=hohmlweb01-aixCell01, Profile=Dmgr01>Shared Libraries > icefaces4.0.0 Classpath: /home/sisorb/icefaces-ace-4.0.0.jar /home/sisorb/icepush-4.0.0.jar /home/sisorb/icefaces-4.0.0.jar /home/sisorb/jfreechart-1.0.19.jar

如果有人至少可以告诉我如何在 Liberty Profile 中重现此类 WAS ND 配置，我将不胜感激。也许我可以通过复制相同的类加载配置来解决该问题。
P.S.:这个问题最初是在其他论坛中创建的，但由于我根本没有得到答案，所以我也在这里分享我的疑问(https://developer.ibm.com/answers/questions/323283/how-can-i-reproduce-same-was-nd-classloader-setup.html)

最佳答案
如上所述，webProfile-7.0 功能包括 jsf-2.2 功能，它提供与您在应用程序中捆绑的 jsf-* jar 相同的 EE 功能 (JSF 2.2)。您可以通过选择使用一种 JSF 实现来解决此问题。有两种选择:
1) 将 JSF 实现与您的应用程序捆绑在一起:从服务器定义中删除 webProfile-7.0 功能，并仅启用您需要的(非 JSF)功能。
2) 从应用程序中删除 jsf-api 和 jsf-impl jar。这是推荐的路线:WebSphere Liberty 提供了 MyFaces JSF 2.2 实现。 Here is some additional information for configuring the jsf-2.2 feature .
关于jsf - 如何在 Liberty Profile 中重现相同的 WAS ND 类加载器设置，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40870544/
