In this case, for what I understood from Pete's explanations, lib3 is going to be scanned for CDI stuff. But this shouldn't happen, so we would also need a way of differentiating lib3 from lib2. I'll stop my explanation here, as I think Pete can fill in the blanks and explain this much better :-)

They are BDAs if they have a META-INF/beans.xml

>    if there are two separate ejb-jars deployed, A and B, and I invoke loadBeanDeploymentArchive at the deployment that represents ejb-jar A, using a class that is in ejb-jar B as parameter, should the deployment be able to find it?

All archives visible. In your example it should be able to do it.

> - what do I do if loadBeanDeploymentArchive fails to find any archive containing the class, should it return null? I'm assuming yes, but I would like to have an ok here, as the javadoc is not explicit about this
 Throw an exception, as this shouldn't happen. (IAE I think). Can you file a WELDINT issue so we update tha javadoc.
