If the Archive is not reachable in the graph, it means that we need to throw IllegalArgumentException. Ales suggested to replace the findArchive call by a lookup in a ClassLoader -> Archive map. That way, all I would need to do is looking up for the archive that corresponds to the beanClass CL. This is faster than walking through the Archive graph, but I wouldn't be able to know whether the Archive is reachable from the current Deployment or not, so I wouldn't be able to throw the IllegalArgumentException to point that beanClass is not visible to the current Deployment. Which way should I go? Should I forego the "is beanClass visible to this Deployment" check and follow Ales's suggestion, or should I keep things the way they are? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554183#554183] Start a new discussion in JBoss Microcontainer Development POJO Server at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Flavia Rainone [http://community.jboss.org/people/flavia.rainone%40jboss.com] replied to the discussion "Implementing a non-flat deployment for Weld Integration" To view the discussion, visit: http://community.jboss.org/message/554152#554152 -------------------------------------------------------------- This is about the TODO comment that Ales added to DeploymentImpl: public BeanDeploymentArchive loadBeanDeploymentArchive(Class<?> beanClass) { // collection to mark the archives we have already searched Collection<Archive> searchedArchives = new HashSet<Archive>(); // collection to mark the classpaths we have already searched Collection<Classpath> searchedClasspaths = new HashSet<Classpath>(); // TODO -- why the search? beanClass' ClassLoader should be mapped to Archive? // need to throw an IllegalArgumentException if the Archive is not reachable from // the archives contained in the archives of this deployment Archive archive = findArchive(beanClass, archives, searchedArchives, searchedClasspaths); if (archive == null) I put a temporary answer right below the TODO as you can see. It is undeniable that Ales' suggested approach is much simpler and faster than searching for the Archive in the graph. The problem is that we need to throw the IllegalArgumentException whenever the Archive is not reachable. I'm wondering if that exception is really necessary, as IMHO the gains of following Ales suggestion outweight the fact that we are not checking for Archive visibility. So, in order for this exception to happen, we would need to assume that Weld is asking for a bean loaded by a ClassLoader that is not visible to the ClassLoader that loaded the current deployment. Would this scenario ever happen? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554152#554152] Start a new discussion in JBoss Microcontainer Development POJO Server at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

The product uses some services from the compendium which are implemented by a number of util bundles. Voila - that's the test case structure. I understand and agree, but I think for this Ales wants a bare-bones comparison between exact classloading and the full visibility model, in this case it will probably be clearer with just one level of classes. I'm working on this now, and should hopefully have something in time for today's meeting. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554118#554118] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
