我正在尝试将应用程序从wensphere 8.5.5.x迁移到Websphere 9。我的应用程序是在Java 7上开发的。我将JRE更改为1.8，并在JDK 1.8上创建了Maven构建，因为WAS 9支持Java8。将应用程序EAR部署到WAS 9并尝试启动应用程序后，我开始为com获取ClassNotFoundException。 .sun.faces.taglib.jsf_core软件包。
我看到一些需要在项目中添加此依赖项的建议。我在pom.xml中添加了依赖项。添加此依赖项后，当我启动应用程序时，它挂起并试图启动，在40-45分钟后，我遇到异常。
我添加的依赖关系以添加com.sun.faces.taglib.jsf_core软件包。
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.2.20</version>
</dependency>

JSF SunRI引擎已在WebSphere传统V9.0中删除。您可以使用WebSphere传统V9.0中包含的MyFaces实现，也可以将自己的JSF引擎与应用程序打包在一起。这是一个文档页面，该页面讨论WebSphere传统V9.0（包括JSF SunRI）中已删除的功能以及如何解决这些功能：https://www.ibm.com/support/knowledgecenter/SSAW57_9.0.5/com.ibm.websphere.nd.multiplatform.doc/ae/rmig_remfeat.html
如评论中所述，建议对您的应用程序运行“应用程序二进制文件迁移工具包（https://developer.ibm.com/wasdev/downloads/#asset/tools-Migration_Toolkit_for_Application_Binaries）”。它将帮助您发现此类问题并告诉您如何解决。它包含有关JSF SunRI删除的信息。
