The J2EE DD API is based on a bunch of interfaces based on the deployment descriptor xml structure. The names of interfaces correspond to the names of deployment descriptor elements in the J2EE DD files like ejb-jar.xml, web.xml or applicaiton.xml. The DD API interfaces are organized in a hierarchic tree structure and are accassible through the root (Application), (WebApp) or (EjbJar) interfaces. The implementation of DD API interfaces is hidden for clients. It is based on schema2beans infrastructure and is the DD version - specific. (there is always requirement to support at least two successive versions of DD specification). The implementation is located in non-public packages of j2ee/ddapi module. It is expected that interfaces will not be implemented by the client.
The root of the deployment descriptor is accessible through the DDProvider class.
