我正在努力将我的应用程序从Jboss 5.1.0 GA迁移到WildFly 8.2.0。作为此迁移的一部分，我使用新版本迁移了一些技术
我在WildFly 8.2.0上成功部署了我的应用程序，并能够加载登录页面。
当我尝试登录我的应用程序时，我收到以下异常。

我怀疑在渲染JSF页面时存在问题，但它在Jboss 5.1.0 GA上使用JSF 1.2正常工作
答案 0 :(得分：2)
Seam 2.3.1与JSF 2.2不兼容。它基本上由DeltaSpike继承。
如果您无法迁移到DeltaSpike，那么最好的办法是使用此答案中详述的说明将WildFly中的Mojarra 2.2.x降级到最新的2.1.x版本：Upgrade JSF / Mojarra in JBoss AS / EAP / WildFly。只需替换＆＃34;升级＆＃34;与＆＃34;降级＆＃34;在所有地方：）
