无法实例化Seam组件: org.jboss.seam.core.ConversationIdGenerator

Question

以下异常的原因可能是什么？我有我的persistence.xml和components.xml看起来正常。环境: JBoss EAP6.3，Seam2框架。我已经成功地启动了服务器，当我尝试访问我的应用程序的url时，我收到了以下错误消息。

有谁能帮我解决这个问题吗？

Answer 1

我已经通过将javassist文件从版本3.18.1更新到3.6.0修复了这个问题。

Jboss eap 6.3服务器使用javassist-3.18.1-GA-redhat-1.jar，但我的应用程序支持javassist-3.6.0.GA.jar

由于jar未匹配，我收到了classFormatError "javassist-3.6.0.GA.jar“。
