You can omit the following DDs with Application Server:

• application.xml for Java EE 5 and Java EE 6
• ejb-jar.xml for EJB 3.0 and EJB 3.1
• web.xml for Servlet 2.5 and Servlet 3.0

The following table describes the combinations of the DD version in application.xml and the omission of the DD, and the DD (ejb-jar.xml, web.xml, and ra.xml) version for each module and the omission of the DD.

Table 11-6 DD combinations

DD types		application.xml
		1.4 or earlier #1	Java EE 5	Java EE 6	No DD
ejb-jar.xml	2.0 or earlier #1	Y	Y	Y	Y
	2.1	Y	Y	Y	Y
	3.0	N	Y	Y	Y
	3.1	N	N	Y	Y

N: Not supported

#1 When the version is upgraded or when the server management commands are executed after the version is upgraded, the version is changed as described below.

#2 Even if the J2EE applications that are already imported with Application Server version 08-70 or earlier are upgraded to version 09-00 or later, the ejb-jar.xml version operates as 3.0 and the web.xml version operates as 2.5.

Table 11-7 Upgrading the DD versions
