Hi,
Hmmm.
application.xml is standard dd for EAR
web.xml is the standard dd for WEBAPP
ejb-jar.xml is the standard dd for
EJB Other than this, each appserver is free to use additional xml for it's server specific setting.
For example, additional ejb setting in weblogic is defined in
weblogic-ejb-jar.xml
To my knowledge, jboss.xml is defining things like the DataSource resource reference etc.
So, you can say that though J2EE is a standard, the deployment is pretty much server specific.
Have I answer your question?
Cheers.
