[jboss-as7-dev] JBoss modules definition for Envers

[Dimitris Andreadis]

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
