I was just about to send a "Thank you!" to jkw privately when I saw your =
response Evan.
I agree completely with jkw's assessment of the state of affairs and the =
possible problems that go along with that. What is distressing is not =
really that it is the way it is (after all, this is largely "virgin =
land", even though some people likes to say "we've been doing this for =
decades"), but that noone (/not that many) have raised these flags =
before. The effects of what jkw outline are both subtle and can affect =
the system during extended production use.
EJB 2.0 CMP makes things better (although at the same time being a heck =
of a lot more complex *and* simpler for the developer...but that's =
another topic..), but only really gives better hooks for containers do =
"do it right". Then there's the issue of actually "doing it right"....
No solution to provide, just wanted to say "yes, jkw is on target" and =
"yes, this needs to be discussed".
