Hello Peter, Thank you for your response. I just got a copy of your book and I am looking forward to learn from it!! Ok, yes I should have numbered them. Next time :) I am going to comment on your numbered responses. 1) and 2) : What if the HTTPServletRequest isn't available? i.e I am in an MBean and need to get the current server session info that contains that information provided by HTTPServletRequest and Session. Is there an JBoss component (MBean) I can access to get that? 3) Thank you. Can you point me to an example on how to access an MBean such as jboss.system:type=Server? 4) I think the how to use LDAP for authentication is done with the Login-config.xml file. How about accessing the information and making calls to the LDAP to find out which users are in a group? Thank you again for your help.
