From what I can see, if it works just like a library in WEB-INF/lib, it means that we will need to provide a BDA for a lib jar only when Weld requests for one through loadBeanDeploymentArchive, right? Or, if I'm wrong, do you mean that a BDA for every lib jar with a META-INF/beans.xml should be provided as direct or indirect result of BeanDeploymentArchive.getBeanDeploymentArchives() for every BDA in a Deployment? Explaining better, given commos/lib/mylib.jar with the following structure: mylib.jar   |_       META-INF/beans.xml   |_      whatever classes in here Say we create a BDA upfront, let's call it MY_LIB_BDA, and add this BDA to DefalutDomain Classpath. No deployment is created upfront. Now, say my-ejb.jar with a META-INF/beans.xml file is deployed to deploy dir. We create a Deployment for it, of course, and we create a BDA for it as well. This BDA, called MY_EJB_BDA, belongs to Default Domain Classpath. So, when Weld invokes MY_EJB_BDA.getBDAs(), it should , directly on indirectly (i.e., by walking on the BDA graph structure), reach MY_LIB_BDA? This is different from the lazy approach because, with this second approach, you are not required to call loadBeanDeploymentArchive in order to obtain MY_LIB_BDA.  A simple BeanDeploymentArchive.getBeanDeploymentArchives will get you there. Is that what Weld requires us to do?

Because the Java EE/CDI specs require it. BTW, I've read the spec sometime ago. Of course I don't remember all the details so, if you think rereading some specific part of it might be useful, let me know.
