Thanks, buddy.
I only did 'copy & paste' here... So, no chance to have a typo. Even because I copied the security-domain from jboss-web.xml to jboss.xml.
Is @SecurityDomain("exemplo1") mandatory? Or only if I do not provide jboss.xml config?
Even providing @SecurityDomain("exemplo1") and jboss.xml, it does not work. Same error occurs.
my bad... please remove this post.
