WildFly 10 JMS client with WildFly 9 broker

[hwellmann.de]

I have two WildFly 9 instances, let's call them Client and Broker, where Broker acts as a stand-alone message broker, and Client runs a web app sending messages to a queue on Broker via an HTTP connector with an outgoing socket binding.

Now I'm trying to upgrade the Client to WildFly 10 while leaving the Broker untouched. I've migrated the messaging subsystem of my client configuration. When starting Client, I see the following in the log:

2016-02-12 11:27:54,800 DEBUG [org.apache.activemq.artemis.core.client] (MSC service thread 1-1) Sending HTTP request DefaultHttpRequest(decodeResult: success, version: HTTP/1.1)

GET  HTTP/1.1

Host: ****

Upgrade: activemq-remoting

Connection: Upgrade

httpPpgradeEndpoint: http-acceptor

Sec-ActiveMQRemoting-Key: i2lLCniGoH7Nx5TuY0XkdA==

2016-02-12 11:27:54,849 DEBUG [org.apache.activemq.artemis.core.client] (MSC service thread 1-1) Connector towards NettyConnector [host=****, port=80, httpEnabled=false, httpUpgradeEnabled=true, useServlet=false, servletPath=/messaging/ActiveMQServlet, sslEnabled=false, useNio=true] failed

So it looks like the WIldFly 10 client is trying to persuade the WildFly 9 broker to do an activemq-remoting upgrade, but all the broker is able to do is an hornetq-remoting upgrade.

Is this scenario supposed to work at all? Is there a configuration option to make the WildFly 10 client talk HornetQ to the old broker?

Harald

You can try using a Netty connector rather than an HTTP connector from your client.  However, I'm not terribly hopeful that it will work.  ActiveMQ Artemis (i.e. the JMS implementation in Wildfly 10) supports older HornetQ clients, but the reverse is not necessarily true.

Yes, Justin is right. You'll need to create netty acceptor on broker and then create legacy-connection-factory on client machine which will have configured connector to broker's netty acceptor. This is the only way how to make this work afaik. This requires to let another port open on broker machine.
