Being an author on EJB myself I was faced with the same issue. I have
chosen not
discuss the syntax of deployment descriptors in neither the old or the
new XML
form. Important are the concepts and implications of things defined in
the
delpoyment descriptor not their syntactical representation. In fact I
expect any
decent EJB development tool to provide Wizard-like support for
deployment
descriptors - remember EJB is supposed to make your job easier not
harder.
Generally I think there are many topics in the EJB specification
irrelevant for
the bean provider aka application programmer. Many pages are solely
focused on
container/server provider. At the URL below you find a chapter on the
EJB spec
from a application programmer's point of view, see for yourself.
Cheers,
Andreas
