I'm migrating my project to JBoss AS 7, and I've read a little about its modules. My problem is simple (I think), I have no idea how to include this modules during development phase. For example, I use hibernate, and inside Eclipse, with JBoss Tools and JBoss AS 6, I just need to say that the project will use JBoss 7 and all their "jars" are available. But using JBoss 7, hibernate-core isn't available to me. I know I have an option to add the hibernate-core as "provided" on my pom, but there is another way?
Take a look at these links:
APIs: http://mvnrepository.com/artifact/org.jboss.as/jboss-as-spec-api/7.1.1.Final
Artifacts provided by the server: http://mvnrepository.com/artifact/org.jboss.as/jboss-as-api/7.1.0.CR1
All other artifacts (I'm not sure which will be the most suitable for you): http://mvnrepository.com/artifact/org.jboss.as
I would say adding the hibernate-core as "provided" on your pom and adding
Dependency: org.hibernate
to your META-INF/MANIFEST.MF or
<dependencies>
<module name="org.hibernate" />
</dependencies>
to jboss-deployment-structure.xml is the way to go. This way you get runtime access to Hibernate bundled with JBoss without including them in your deployment. Just make sure you use the same version of Hibernate that comes with JBoss (Hibernate 4.0.1 for JBoss AS 7.1.1). Also check out the Developer Guide.
