我正在尝试在WildFly8.2上运行我的应用程序，它是使用Jboss 5.1构建的。我迁移了我的整个应用程序并能够看到登录页面。但是在导航到JSF页面时，它会抛出以下异常。
我的旧应用程序基于JSF 1.2构建

我怀疑这个问题是因为我的jsf或富有面孔的罐子，但是我正在研究这个问题。
如果有人知道解决方案，请告诉我。

这是由Seam 2.3.x和JSF 2.2组合引起的。您需要{J}兼容migrate Seam到DeltaSpike，或者WildFly中的downgrade Mojarra 2.2.x到2.1.x.
技术问题是，Seam使用的an Application implementation没有从javax.faces.application.ApplicationWrapper及it had to manually implement/delegate all Application methods to the wrapped application正确延伸。对于Seam 2.3.x，所有这些方法都基于JSF 2.1。在JSF 2.2中，Application添加了一个新方法getFlowHandler()，该方法未被Seam正确委派，因此返回null，导致依赖链中的所有麻烦它不是null。如果Seam人员从ApplicationWrapper正确扩展而不是硬编码特定JSF版本的所有委托方法，那么它将完美地适用于JSF版本。

我已经确定了根本原因，问题是因为jar版本，将jar版本降级为2.1.29-jbossorg-1，它对我有用。
为此，将jar添加到$ {JBOSS_HOME} / modules / system / layers / base / com / sun / jsf-impl / main / 并更新module.xml（在同一路径中可用） “resource-root”标记指向新文件名。
