So you decided to use a custom module in JBoss EAP6/AS 7 and your setup is domain mode where your host and domain are on separate machines, and you add a module in your domain controller ... and still getting errors in logs that JBoss is unable to find required module?

Make sure to add the module to your host instance as well since domain mode only pushes deployable contents onto hosts, and module is not a deployable content.

Keep Jbossing....
