How to manually deploy an application in domain mode in EAP 6?

Issue

• How to manually deploy .war or .ear file into domain jboss eap 6 ?
• I have added deployment scanner option into domain.xml file to

 <subsystem xmlns="urn:jboss:domain:deployment-scanner:1.1">
            <deployment-scanner path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000"/>
        </subsystem>

Trying to start the server, server fails to start. Following is the error :

ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) JBAS014612: Operation ("parallel-extension-add") failed - address: ([]): java.lang.RuntimeException: JBAS014670: Failed initializing module org.jboss.as.deployment-scanner
