我正在尝试编写一些Java代码，它们将通过线程读取视图。我使用Callable而不是Runnable，如果我将它作为远程应用程序运行，它可以正常工作，即使用NCSO.jar以Java CORBA / DIIOP方式连接到Domino。 现在，当我尝试将相同的代码移动到我的数据库时，我遇到了多个错误。最新的是 HTTP JVM：java.util.concurrent.ExecutionException：java.lang.IllegalStateException：未为线程初始化NotesContext 。这是我的代码。 AccessRequests（后面的类）是主AccessRequestsViewNav类的worker。我正在读取1000个条目的块视图，所以我动态创建ThreadPool和线程。当我从eclipse运行它作为外部应用程序时，这是工作代码，但是当我在NSF文件中实现相同的代码时。 这是NSF中的代码 的 AccessRequestsViewNav.java
