However, there are only all, default, and minimal directories are there. Is this an error in the document or the contents of the JBoss AS 4.2.2 archive?
Looks like an error in the documentation. The JBoss distribution comes with "all", "default" and "minimal".
That document is actually for the JBoss EAP distribution, which is available only with a support subscription. EAP comes with two base directories - jbossas and seam. The jbossas that comes with EAP contains the three standard configurations (all, default, minimal) and and additional production configuration.
