If you want to be super-tricky with env-entries, and <vendor>if your server
supports automatic hot redeployment (such as jBoss)</vendor>, you can have
some other code write to that deployment descriptor's env-entry elements,
changing the values based upon some other computation (for example, a legacy
C application fired off by some legacy ftp app that rewrites the values in
the decriptor), causing the values read by the ejb to be dynamic instead of
static.
Of course, if your values are changing frequently you should simply use some
datastore, even if that datastore is merely a file, since EJB's have such
clean datastore and resource factory access semantics.
