我刚刚下载了 JBoss Portal Server 2.7.2（准确地说是 JBoss Portal + JBoss AS 4.2.3 捆绑包）并尝试像示例中提供的 SimpleHelloWorld 一样部署 portlet。portlet 部署得很好，但是当我把它放在一个页面上时，我得到了以下异常。我也尝试添加其他 Portlet（例如 Spring WebFlow dist 提供的预订 MVC portelt），但同样的问题发生了。
当我创建新实例时会出现问题，例如当我创建 CMS Portlet 的新实例时，我会收到相同的错误。如果我使用现有实例，它可以工作。如果我部署一个使用“portle-instances.xml”创建实例的 portlet，那么它可以正常工作，但是由于以下错误，使用 Admin 创建其他实例并在页面上部署它们会失败。
我究竟做错了什么？有人可以帮忙吗？
