JavaEE 6 contains Servlet 3.0 and is supported by JBossAS 6.0.0.M2.

However, the web.xml editor cannot show the tree view when WEB-INF/web.xml contains:
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">

There are two changes regarding the Servlet 2.5 spec:

• web-app_3_0.xsd and
• version="3.0"
