I am looking at the org.hibernate modules definition in AS7: - <module xmlns="urn:jboss:module:1.0" name="org.hibernate"> ... - <dependencies> ... <module name="org.hibernate.envers" services="import" optional="true" /> </dependencies> </module> Then at envers: - <module xmlns="urn:jboss:module:1.0" name="org.hibernate.envers"> ... - <dependencies> <module name="org.hibernate" /> ... </dependencies> </module> Are cyclical dependencies allowed?

Also, what's the service="import" clause really about? What's a service in this context?

I might miss some detail, but I hope this will help you for now.

Yes, as long as there are no exports in those involved modules.

Imo, Envers wants for Hibernate to see this Skywalker:main alesj$ unzip -c hibernate-envers-4.0.0.CR2.jar META-INF/services/org.hibernate.integrator.spi.Integrator Archive: hibernate-envers-4.0.0.CR2.jar inflating: META-INF/services/org.hibernate.integrator.spi.Integrator org.hibernate.envers.event.EnversIntegrator _______________________________________________ jboss-as7-dev mailing list jboss-as7-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-as7-dev

Hi there, I am looking at the org.hibernate modules definition in AS7: -<module xmlns="urn:jboss:module:1.0" name="org.hibernate"> ... -<dependencies> ... <module name="org.hibernate.envers" services="import" optional="true" /> </dependencies> </module> Then at envers: -<module xmlns="urn:jboss:module:1.0" name="org.hibernate.envers"> ... -<dependencies> <module name="org.hibernate" /> ... </dependencies> </module> Are cyclical dependencies allowed? Also, what's the service="import" clause really about? What's a service in this context? From the doc: https://docs.jboss.org/author/display/MODULES/Module+descriptors: Specify whether this dependency's services* are imported and/or exported. Possible values are "none", "import", or "export"; defaults to "none". Thanks in advance /D _______________________________________________ jboss-as7-dev mailing list jboss-as7-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-as7-dev

You could break the cyclic dep if hibernate supported using a separate classloader to load an extension.
