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.

The wsadmin scripting client is run from Qshell. For more information, see Configuring Qshell to run WebSphere Application Server scripts using wsadmin scripting .

Command-line help is provided for service integration bus commands:

Purpose

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).

Required parameters

None.

Conditional parameters

-namespace
The namespace of the WS-Notification topic namespace to be displayed. This must be specified if the target type is WSNService, and must not be specified if a WSNTopicNamespace target is supplied.

Optional parameters

None.

Example

Show the properties of the WS-Notification topic namespace newTopicNamespace created in the example from topic "Creating a new permanent WS-Notification topic namespace by using the wsadmin tool" :
  • Using Jython:
    AdminTask.showWSNTopicNamespace(newTopicNamespace)
  • Using Jacl:
    $AdminTask showWSNTopicNamespace $newTopicNamespace
Show the properties of the WS-Notification topic namespace newTopicNamespace created in the example from topic "Creating a new permanent WS-Notification topic namespace by using the wsadmin tool" using the WSNService target pattern:
  • Using Jython:
    AdminTask.showWSNTopicNamespace(newService,
     ["-namespace", "http://example.org/topicNamespace/example1"] )
  • Using Jacl:
    $AdminTask showWSNTopicNamespace $newService 
    {-namespace http://example.org/topicNamespace/example1 }
