We're trying to run the External MQ Client Example on a single child container of a single ensemble node for our Fabric.

The child container has been configured with the native mq profile applied, and is otherwise untouched.

That profile itself is unmodified.

We've also tried the below with a custom broker group as opposed to default; the results are the same; a zookeeper "NoAuth" error is received (see final section of post).

Customisation of External MQ Client Project

We've slightly customised the External MQ Client Example as follows:

1. Two version properties have been updated to the following, since we run Fuse Fabric 7.1 GA (i.e. the 047 RC):

*          <activemq.version>5.7.0.fuse-71-047</activemq.version>

*          <fabric.version>7.1.0.fuse-047</fabric.version>

2. We provide an explicit username/password at point of creating a Connection:

•               connection = factory.createConnection("admin","admin");

•               // we've also tried "karaf","karaf" in the line above.

3. We've added the dependency fabric-activemq to the project POM to provide the class FabricDiscoveryAgent. The latest version we could find is 1.0:

*          

•                       <version>1.0</version>

*          </dependency>

User configuration in Fabric

We have added these two lines..

•          karaf=karaf,admin

•          admin=admin,admin

..to both of these files:

•          $FABRIC/etc/users.properties

•          $FABRIC/instances/<broker-container-name>/etc/users.properties

Running the project -> Zookeeper "NoAuth"

Here's what mvn -e -Pproducer-default prints out when run on the fabric host:

Any suggestions what might be misconfigured?
