将org.jboss.seam.pdf.DocumentStorePhaseListener.beforePhase中的java.lang.NullPointerException异常处理将我的应用程序从Jboss 5.1.0 GA迁移到WildFly 8.2.0。作为此次迁移工作的一部分，我迁移一些技术与新版本将Seam 2.3.1项目从JSF 1.2迁移到JSF 2.x
- JSF 1.2％〜2.0
- RichFaces的3.3.3
- 的Hibernate 4.0.1
- JBoss Seam的2.3.1
我在WildFly 8.2.0上成功部署了我的应用程序，并且能够加载登录页面。
当我试图登录到我的应用程序，我得到下面的异常。

我怀疑有问题，而渲染JSF页面，但它工作在JBoss 5.1.0如预期GA与JSF 1.2
您是否验证过Seam 2.3.1是否与JSF 2.2兼容？ – BalusC
等一下，你的堆栈跟踪提到了JSF API 2.2.8和JSF impl 2.1.29，这显然是版本冲突。你试图瞄准什么版本？你究竟试图将WildFly的内置Mojarra 2.2.8降级到Mojarra 2.1.29？这部分也不好看。 – BalusC
我已经验证了小PoC，煤层2.3.1正在处理包含JSF 2.2的wildfly 8.2.0 –
