13:57:02,478 ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) JBAS015010: The deployment scanner found a directory named META-INF that was not inside a directory whose name ends with .ear, .jar, .rar, .sar or .war. This is likely the result of unzipping an archive directly inside the /opt/EAP-6.1.0/jboss-eap-6.1/server2/deployments directory, which is a user error. The META-INF directory will not be scanned for deployments, but it is possible that the scanner mayfind other files from the unzipped archive and attempt to deploy them, leading to errors.
