According to:
http://docs.jboss.org/jbossas/whatsnew40/html_single/
We read:
From JBoss AS 4.0.1, the server configuration names switch back to the JBoss 3.2 convention. The default configuration uses the JBoss optimized class loader and the standard configuration goes away. The J2EE 1.4 certified configuration of JBoss (i.e., the default configuration in JBoss AS 4.0.0) is distributed in a separate package from JBoss AS 4.0.1.
Where can I obtain this package? Please help.
This page is incorrect. There is no seperate distribution. The only difference is the default call by value beahvior and class loader isolation. Read the readme.html enclosed in the release on how to configure this behavior.
