Bean defining annotations and @Named

A bean class may have a bean defining annotation, allowing it to be placed anywhere in an application, as defined in Bean archives. A bean class with a bean defining annotation is said to be an implicit bean.

The set of bean defining annotations contains:
  • @ApplicationScoped, @SessionScoped, @ConversationScoped and @RequestScoped annotations,
  • all other normal scope types,
  • @Interceptor and @Decorator annotations,
  • all stereotype annotations (i.e. annotations annotated with @Stereotype),
  • and the @Dependent scope annotation.
@Named is not a bean defining annotation. @Named has only one usage : expose your bean to the UI. Other usages are for bad practice or compatibility with legacy framework.

How to fix: mv: failed to preserve ownership

mv  is the wrong tool for this job; you want  cp  and then  rm . Since you're moving the file to another filesystem this is exactly what  mv  is doing behind the scenes anyway, except that  mv  is also trying to preserve file permission bits and owner/group information. This is because  mv  would preserve that information if it were moving a file within the same filesystem and  mv  tries to behave the same way in both situations. Since you don't care about the preservation of file permission bits and owner/group information, don't use that tool. Use  cp --no-preserve=mode  and  rm  instead. But if you don't care about the warning, mv actually does move the files before complaining  ownership problem.
