The JBoss AS 7 quickstart tutorial (https://docs.jboss.org/author/display/AS7/Login+quickstart) reads "Switch to the quickstarts/login directory".
However no such folder exists:
find jboss-as-quickstarts-7.1.1.CR2/ | grep login
... outputs nothing.
That was for AS 7.0 and from what I know, it no longer exists. Take a look at the latest docs here https://docs.jboss.org/author/display/AS71/Quickstarts
