我有一个使用“IceFaces”构建的用户界面。它部署在使用“LifeRay”构建的门户上。UI 应用程序有时会从门户中自动取消部署。日志显示以下错误消息：

UI 只有.xhtml页面，没有 jsp 页面，所以我不知道它为什么要渲染.jsp主页。此外，在再次部署后，它会在异常重新出现之前正常工作一段时间。

如果您能提供任何指向根本原因或如何解决此问题的指针，将不胜感激。

提前致谢

您的 web.xml 中有以下内容吗？

   <context-param>
      <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
      <param-value>.xhtml</param-value>
   </context-param>
