Check https://developer.jboss.org/thread/176211 ;) In theory it should be: <?xml version="1.0" encoding="UTF-8"?> <jboss-deployment-structure> <deployment> <dependencies> <module name="deployment.app2.ear.modules.war" export="true"/> </dependencies> </deployment> </jboss-deployment-structure> Use export=true to ensure the dependency will be available to subdeployments of the EAR. Otherwise, you can assign dependencies to individual subdeployments too: For example, if you have myweb.war subdeployment in app1.ear: <?xml version="1.0" encoding="UTF-8"?> <jboss-deployment-structure> <sub-deployment name="myweb.war"> <dependencies> <module name="deployment.app2.ear.modules.war"/> </dependencies> </sub-deployment> </jboss-deployment-structure> On Tue, Jun 5, 2018 at 12:26 PM, wildflyuser <elayaraja.s(a)gmail.com&gt; wrote:
