Mmh,
looks like that the documentation you found is out of date.
The official site I use is http://community.jboss.org/wiki/JBossApplicationServerOfficialDocumentationPage but here I found your link :(
and the Admin Guide is a dead link.
=> Jaikiran, a question for you, how do report this kind of documentation errors? broken link and outdated chapters?
For HornetMQ you should use the related links, but because there is no database there is nothing to change.
