使用脚本启动并与 WS-Notification 一起快速运行
使用 Jython 脚本来配置必需的资源以启动并与 WebSphere® Application Server 中的 WS-Notification 一起快速运行。
开始之前
关于此任务
您可以使用示例脚本来配置一组缺省资源,这些资源使您能够连接 WS-Notification 应用程序以便进行开发。此脚本在执行时将完成下列操作:
- 它在配置中搜索现有的服务集成总线,并且将根据需要创建服务集成总线。
- 它搜索现有的总线成员,如果找不到任何总线成员,它会向总线添加(独立)服务器并使用缺省数据源。
- 它搜索现有的服务集成总线主题空间目标,并且将根据需要创建服务集成总线主题空间目标。
- 它创建 V6.1 或 V7.0 WS-Notification 服务。
- 它在本地服务器上为 SOAP over HTTP 绑定创建 V6.1 或 V7.0 WS-Notification 服务点。
- 它创建 WS-Notification 永久主题名称空间以引用步骤 3 中找到的或创建的服务集成总线主题空间。
- 它保存配置,并描述在什么位置查找已公开的新通知代理 Web Service 的 WSDL。
要使用示例脚本,请完成以下步骤:

# WS-Notification QuickStart script #
# #
# This Jython script will quickly create the basic resources required in order to #
# start using WS-Notification in WebSphere Application Server Version 6.1 or later #
# #
# Before executing it you must modify the variables defined below to match your #
# configuration settings. #
# #
# Note: #
# - This script is not intended for production use, and is intended for use on #
# a stand-alone server (not network deployment) only. #
# - The script will search the configuration for an existing bus, and if one is #
# not found then a new bus will be created #
# - It will then look for an existing Bus Member on the chosen bus. If one is not #
# found then one will be created using the default File Store #
# - It will then look for an existing service integration bus topic space. If one #
# is not found then it will create one. #
# #
# Execute the script by typing; #
# wsadmin -f wsnQuickStart.py #
