尝试访问我的应用程序的登录页面时，它显示以下错误。一些细节：

  1. 应用程序使用 Scala Lift 框架。
  2. JBOSS 6.2.0 EAP。
  3. 部署的上下文根是 /cpt

可能的原因是什么？谢谢。！

TL;DR - 尝试一次重建一个不依赖项的项目 - 特别是 log4j。

答案在于 JBOSS 如何加载库。如果它遇到它已经作为服务器库的项目库，则类加载器会中断。通常是由于 logger log4j lib。因此，请尝试删除此依赖项并使用替代记录器。当然，这也需要您更改代码。

至少，这是我们的情况。

还没有答案。我们在 JBoss EAP 6.2 中遇到了类似的错误（LinkageError、NoClassDefFoundError、ClassNotFoundError），但还没有找到解决方案。我们怀疑“新”模块化类加载器中存在错误。
