Philippe,
I was not running this as a Dynamic Web Project. I am now, and my deployment is failing. This is the message:
14:47:01,530 ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 2) {"JBAS014653: Composite operation failed and was rolled back. Steps that failed:" => {"Operation step-2" => {"JBAS014771: Services with missing/unavailable dependencies" => ["jboss.deployment.unit.\"BriefReqPersistSPRING.war\".WeldServicejboss.persistenceunit.\"BriefReqPersistSPRING.war#org.persistence.unit\"Missing[jboss.deployment.unit.\"BriefReqPersistSPRING.war\".WeldServicejboss.persistenceunit.\"BriefReqPersistSPRING.war#org.persistence.unit\"]"]}}}
I'm going start a more detailed discussion in a new thread. Thanks for your help. If you can lend any assistance here, please let me know!
