7.2. Connecting to a Broker

Overview
Copy link

This section describes how to connect a client to a broker. In order to connect to a JBoss MQ broker, you need to know its group name. Every MQ broker is associated with a group when it is created: if none is specified explicitly, it automatically gets associated with the default group.

Client URL

To connect to an MQ broker, the client must specify a discovery URL, in the following format: 
discovery:(fabric:GroupName)

For example, to connect to a broker associated with the default group, the client would use the following URL: 
discovery:(fabric:default)
Copy to Clipboard Toggle word wrap
The connection factory then looks for available brokers in the group and connects the client to one of them.

Example client profiles

You can test broker by deploying the example-mq profile into a container. The example-mq profile instantiates a pair of messaging clients: a producer client, that sends messages continuously to the FABRIC.DEMO queue on the broker; and a consumer client, that consumes messages from the FABRIC.DEMO queue.
Create a new container with the example-mq profile, by entering the following command: 
JBossFuse:karaf@root> fabric:container-create-child --profile example-mq root example

You can check whether the example container is successfully provisioned, using the following console command: 
JBossFuse:karaf@root> watch container-list
Copy to Clipboard Toggle word wrap
After the example container is successfully provisioned, you can connect to it and check its log to verify the flow of messages, using the following console commands: 
JBossFuse:karaf@root> container-connect example
JBossFuse:karaf@example> log:display
