External client connecting to Wildfly14 artemisMQ Queue.

[ninjasftw]

Hi,

I'm looking to port an app that talks to a standalone ArtemisMQ to a Queue within an Wildfly 14 instance.  The test code works fine against a standalone ArtemisMQ instance.

I'm using the golang library @ GitHub - vcabbage/amqp: AMQP 1.0 client library for Go.

and have setup the wildlfy instance

<jms-queue name="testqueue" entries="java:jboss/exported/testqueue testqueue" durable="true"/>

...

<remote-acceptor name="messaging-amqp" socket-binding="messaging-amqp"/>

...

<socket-binding name="messaging-amqp" interface="public" port="5672"/>

The startup logs show that the acceptor initilizes ok

2018-11-05 12:06:04,290 INFO  [org.apache.activemq.artemis.core.server] (ServerService Thread Pool -- 78) AMQ221020: Started EPOLL Acceptor at XX.XX.XX.XX:5672 for protoco
ls [CORE,AMQP,HORNETQ,STOMP]

When I then try and connect I get the following exception thrown.

There isn't a SaslListener class in the jar file at /apps/wildfly14.0/modules/system/layers/base/org/apache/qpid/proton/main

Should there be?

Looks like that proton-j-0.27.3.jar is missing. Could you try to add it to org.apache.activemq.artemis.protocol.amqp module. Copy it to wildfly-14.0.0.Final/modules/system/layers/base/org/apache/activemq/artemis/protocol/amqp/main directory and update module.xml so it's loaded. I think that the reason why it's not working is that it requires SASL from proton-j.

Hi mnovak,

Yes that's it exactly.  Added it and its all working fine now.

Thank you

Thanks for finding this issue. I've created jira [WFLY-11289] Artemis AMQP protocol requires proton-j...jar if SASL is used so developers can consider to add this missing dependency. It's not convenient to add it manually. Of course I've mentioned you on the jira, credit goes to you ;-)
