Yes.
Isn't this what "deploying" is all about.
IMHO, there is a mis-perception as to what "deploying" means.
I think many see this as a way of "fixing bugs" or doing "upgrades" or
something.
"hot deploy" is a paradigm.
Configuration should be thought of as a "part" of the bean. Executable
content if you will.
When you want the bean to behave differently ... whether it be code or
configuration ... "deploy" a new instance.
Simple and crispy clean.
What is so hard about that ?
Why is using a property file easier ?

""The use of EnvEntry's in the descriptor is the
recommended way.""
This is silly. It means I have REDEPLOY my bean in
order to tweak a configuration ???
All I am saying is that the spec prohibits the use of
**java.io** to read a properties file.
My recommendation is to use an app server startup
class to read in an XML file and set configuration
values in JNDI where they can subsequently be looked
up safely by EJBs inb the setSession method.
