3.6.3. Disable Subdeployment Class Loader Isolation Within a EAR

This task shows you how to disable Subdeployment class loader isolation in an EAR deployment by using a special deployment descriptor in the EAR. This does not require any changes to be made to the application server and does not affect any other deployments.

Important

Even when subdeployment class loader isolation is disabled it is not possible to add a WAR deployment as a dependency.
  1. Add the deployment descriptor file

    Add the jboss-deployment-structure.xml deployment descriptor file to the META-INF directory of the EAR if it doesn't already exist and add the following content:
    <jboss-deployment-structure>
    
    </jboss-deployment-structure>
    
  2. Add the <ear-subdeployments-isolated> element

    Add the <ear-subdeployments-isolated> element to the jboss-deployment-structure.xml file if it doesn't already exist with the content of false.
    <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
    
Result:

Subdeployment class loader isolation will now be disabled for this EAR deployment. This means that the subdeployments of the EAR will have automatic dependencies on each of the non-WAR subdeployments.
