I'm really confused by what you're saying here - there is no JBoss AS 4.6. Did you install it onto JBoss AS 6? or JBoss AS 4.2.3?
I'd suggest starting at the Getting Started Guide, which contains detailed installation instructions for installing the ESB into various versions of JBoss As.
sorry, my mistake, it's JBoss AS 6.
Thank u for your suggestion.
