如何在自由配置文件中复制相同的ND classloader设置

Question

我有一些基于JSF和CDI的web操作，它在Websphere ND8.5中工作得很好。然而，它在Liberty Profile16(WebSphere Application Server 16.0.0.3/WLP-1.0.14)中不起作用。如果我试图用已经部署的战争来启动自由配置文件，它会导致

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

<webApplication id="myWebApp" location="myWebApp.war" name="myWebApp">
 <classloader delegation="parentFirst"/>
</webApplication>

<webApplication id="myWebApp" location="myWebApp.war" name="myWebApp">
 <classloader delegation="parentLast"/>
</webApplication>

我听到有人说，这是因为反射（CDI依赖的某些特性）在Liberty Profile中不起作用，但在WAS ND中却起作用。老实说，我不认为这是一个最终的解释。我倾向于相信这是一些与classloader相关的技巧，我忽略了这些技巧。

整个库列表如下：

"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，I successfuly使用以下设置启动相同的web应用：

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：

如果有人能至少告诉我如何在自由配置文件中复制这样的WAS ND配置，将非常感谢。也许我可以通过复制相同的类加载配置来修复这个问题。

Answer 1

从第二个堆栈跟踪来看，应用程序中的一个JAR似乎正在注册CDI扩展。当这个扩展被调用时，它试图加载CDI11Util服务，但没有获得预期类型的对象。

我怀疑可能是jsf-impl.jar在做这件事。在使用WebProfile-7.0特性（包括JSF）时，不应该在应用程序中提供自己的JSF实现。你能试着把这个罐子移开吗？

顺便说一句，您不应该需要servlet、faces、inject或jsf API JAR，因为服务器将为您的应用程序提供这些类。

另一个附带说明是，Liberty中默认的classloader设置正如您在问题中所描述的那样（classloader首先是父级，每个WAR都有自己的classloader）。
