Chapter 6. Managing JMS Queues and Messages
Overview
You can create, edit, and delete message queues for JMS brokers from the ActiveMQ page of the Container perspective. You can also search for messages, move, and resend messages directly from the queue.

- Connect to the container and open the ActiveMQ page.
- Select the top-level node in the tree and click the Create button in the toolbar. The details pane shows a text box and a type selector.
- Enter a name for the queue and make sure to select the Queue radio button. The queue appears in the Queue folder under the top-level node in the tree.
Managing queues and messages

- Attributes
