With Application Server, you can omit application.xml, ejb-jar.xml, and web.xml. However, depending on the combination of the module and DD versions, you might not be able to omit application.xml, ejb-jar.xml, or web.xml.

This section describes the combination of the omitted DD values in the applications running on Application Server and the operations when the DD is omitted.

The following table describes the organization of this section.
