I Installed JBoss4.0.3RC1 and, accepting all the defaults, used "default" as the name of my server. I then create a new EJB3.0 project using the Eclipse IDE and create a server configuration within the wizard. When I look at Properties | Java Build Path | Libraries and look at the JBoss EJB3 libraries, they refer to the 'all' instance instead of 'defualt'. They are not editable. Also, the ejb3-persisitence.jar was not included.
