> Roughly speaking, this is how we would fill in the gaps of the TODO mark you added in your getLibraries method:
OK, refactored things a bit, I now have this:

                  // create an ArchiveInfo with the ClassLoader
                  ArchiveInfo archiveInfo = new ArchiveInfo(cl);
                  // finally create the Archive
                  Archive archive = ArchiveFactory.createArchive(archiveInfo, new ArrayList<EjbDescriptor<?>>());   
                  // ... and the corresponding BDA
                  ServiceRegistry serviceRegistry = new SimpleServiceRegistry();
                  // TODO: fill in serviceRegistry? With which services?
                  // the env
                  WeldDiscoveryEnvironment environment = archiveInfo.getEnvironment();
                  // fill in the Weld classes
                  // the WBDiscoveryVisitor from ArchiveDiscoveryDeployer... 
                  ResourceVisitor visitor = environment.visitor();   
                  Module module = entry.getKey();
                  for (VirtualFile child : files)
                     URL beansXmlURL = child.getChild(provider.getResourceName()).toURL();   
                     module.visit(visitor, ClassFilter.INSTANCE, null, child.toURL());   

It all compiles. :-)

> The other piece of code that we are missing is the part that invokes this, right? At some point we need to fill in the DefaultDomain Classpath (take a look at ClasspathFactory for more details) with the lib BDAs created by your getLibraries method. As we agreed before, this should be done ideally at the first weld deployment. So, I would simply add a piece of code to ClasspathFactory that calls getLibraries, unless you prefer this call to be performed somewhere else.
OK, I still need to think about this one a bit.

> I think that the best way to check everything is working ok is adding a Weld jar to jboss lib prior to start up and make sure that a BDA is being created for it. Other than that, I don't have any use cases :-).
Yup, I'll create a simple test for this -- probably (until we do have a *real* CDI lib present) I'll have to create a new server config for it.
