Hi Tang.
In order to have the @Named(ServerEnvironment.DEFAULT_INSTANCE_NAME)
work, you need to use the
com.sun.enterprise.configapi.tests.ConfigApiTest in the
nucleus/admin/config-api module. This class has a decorate method that
creates the necessary index entries. Or, copy the decorate method into
your ATest class.
