showWSNTopicNamespace command
Use the showWSNTopicNamespace command to show the properties of a WS-Notification topic namespace. A topic namespace is a grouping of topics that allows information to be shared between applications. You use a permanent topic namespace to statically define the association between a WS-Notification topic namespace URI and a service integration bus topic space destination.
To run the command, use the AdminTask object of the wsadmin scripting client.
Command-line help is provided for service integration bus commands:
- For a list of the available WS-Notification commands, plus a brief description of each command, run at the wsadmin prompt:
print AdminTask.help('WSNotificationCommands')
- For overview help on a given command, run at the wsadmin prompt:
print AdminTask.help('command_name')
This command shows the properties of a WS-Notification topic namespace in a human-readable form. There are two patterns for use of this command:
- The required WS-Notification topic namespace is determined by the target WS-Notification topic namespace.
- The required WS-Notification topic namespace is determined by a combination of the target WS-Notification service, and the namespace of the WS-Notification topic namespace provided as a parameter.
Target object
There are two choices for the target type of this command:
- WSNTopicNamespace (explicitly nominates the WS-Notification topic namespace to be shown).
- WSNService (determines the required WS-Notification service; must be used in combination with the namespace parameter).
