Info
titleSubscribing to Topics/Queues

Explained above are the list of role-based permissions that are required by users in order to create and manage queues/topics from the Management Console.

Note

Note that the permission to create topics/queues also includes the permissions for publishing messages to that topic/queue and consuming the messages published to that topic/queue.

Once queues and topics are created in the Management Console, other users should be able to publish to these topics/queues and consume the messages that are published. Therefore, the creator of the topic/queue should grant permissions to other user roles at the time of creating the topic/queue as shown below.

  • When adding a topic from the Management Console, all the available user roles will be listed as shown below. The topic creator can then select the relevant check box to grant the relevant permissions. See the detailed instruction on creating topics in WSO2 MB.
  • When adding a queue from the Management Console, all the available user roles will be listed as shown below. The queue creator can then select the relevant check box to grant the relevant permissions. See the detailed instruction on creating queues in WSO2 MB.
