[Adrian Brock (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBDEPLOY-222?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adrian Brock closed JBDEPLOY-222.
---------------------------------

    Fix Version/s: JBDEPLOY-2.2.x
       Resolution: Done


You can now explicitly configure a subdeployment to have a top level classloader like this:

<classloading xmlns="urn:jboss:classloading:1.0"
                name="mywar.war"
                domain="DefaultDomain"
                top-level-classloader="true"
                export-all="NON_EMPTY"
                import-all="true">
</classloading>

> AbstractClassLoaderDescribeDeployer overrides domain name for this sub-deployment's ClassLoadingMD, as it has no parent domain specified.
> Hence this sub-deployment is always isolated, although it should be part of DefaultDomain.
