My situation is as follows:

I have a JBoss (EAP 6.1) instance running with a WAR deployment. I want to use Arquillian to do integration testing against this existing deployment, however, the developed classes and tests that I am deploying to this instance (in another separate WAR) have dependencies on classes that are loaded by the existing WAR deployment. How to I configure my new test WAR to correctly reference those classes?

I have tried adding a MANIFEST.MF Class-Path: deployment.<existing-deployment>.war

and also by adding a dependency through jboss-deployment-structure.xml.

However, I keep on getting:

java.lang.Exception: {"JBAS014771: Services with missing/unavailable dependencies" => ["jboss.module.service.\"deployment.<my-test-class>.war\".main is missing [jboss.module.spec.service.\"deployment.<existing-deployment>.war\".main]"]}

at org.jboss.as.controller.client.helpers.standalone.impl.ServerDeploymentPlanResultFuture.getActionResult(ServerDeploymentPlanResultFuture.java:134)

...

Is it at all possible to reference loaded classes on a running JBoss instance?

Any help will be greatly appreciated.
