Hi Martin,

Could you or someone else explain what is the difference between getResource(String name) and getResources(String name) in ResourceLoader? And, could anyone explain how Weld detects what archives it must scan? For examlpe, if from getResource I return `jar:file:///home/user/../jar/my-archive-0.1.0-SNAPSHOT.jar!/META-INF/beans.xml` , does it mean that Weld will scan my-archive-0.1.0-SNAPSHOT.jar as it will get the path to archive from this URL?

Best regards, Alex
