通过编程添加文件

您可以通过管理控制台、wsadmin 工具或编程,将文件添加至现有的应用程序。此示例描述了通过编程添加文件的方法。

开始之前

此任务假设您对 MBean 编程有基本的了解。有关 MBean 编程的信息,请参阅 MBean Java™ 应用程序编程接口 (API) 文档。 在此信息中心中,单击引用 > MBean 接口

您必须首先在 WebSphere® Application Server 上安装了应用程序,才能将文件添加到该应用程序。

关于此任务

执行以下各项任务,从而通过编程将文件添加到应用程序。

过程

  1. 连接到 WebSphere Application Server
  2. 创建应用程序管理代理。
  3. 创建用于侦听事件的通知过滤器。
  4. 添加侦听器。
  5. 将文件添加到应用程序。
  6. 如果超时请等待,以使程序不会结束。
  7. 侦听 Java 管理扩展 (JMX) 通知,以了解操作的完成情况。
  8. 在添加文件后,请移除侦听器,然后退出。

结果

成功运行代码之后,文件就被添加到应用程序。

示例

以下示例显示了根据先前几个步骤将文件添加到应用程序的方法。为了便于打印,某些语句被拆分为几行。
