ShrinkWrap.create(WebArchive.class)
  .addClasses(A.class, B.class)
  .addAsWebInfResource(
      Descriptors.create(BeansDescriptor.class).alternative(A.class));

ShrinkWrap represents a subset of the full application and can link the added resources back to the original file on disk instead of having to write everything to a tmp folder and reference the dir in rebel.xml. Referencing the full original dir e.g. target/classes will deploy a lot more then just the defined subset.
