Newbie: can not configure JBoss security for JLCP

Hi!

I'm embarrassed, but have to ask. I built and installed JLCP into JBoss 
(created a DB, created an EAR, deployed), but as I try to access jlcp, 
it blows up since neither "user.properties" nor "roles.properties" file 
is present. I guess, the security has to be configured using database, 
but how exactly?

JLCP is 0.5.0, I believe.
JBoss is 3.0.7.

Thanks!
Denis.
