Also good.

Be careful not to count your chickens before they hatch. This
standard taglib has yet to be written. We all (myself included)
are going to try to make it the best it can be, but the reality
is almost always less ideal than you imagine.

I made clear in the article where a standard tag library would help
out. I also pointed out that such a library has yet to be written.
Not even a little demo one yet that I know of. That makes me suspect
it's a hard task, but more importantly it implies that we're blazing
new ground here and may not yet know enough about this technology area
to define a good standard. We all know it's hard to make an early
implementation the Right implementation. I'm not saying it can't
happen. Just be realistic.

It's interesting you say that right after Tom Reilly wrote:
My main concern is memory consumption. Someone else pointed out
that memory is still fairly cheap, but in general I dislike
an architecture where things can never be unloaded from memory.
Considering that some people view it as a problem, it belongs in an
article titled "The Problems with JSP".

EJB isn't a replacement for servlets/JSPs. Someone has to speak HTTP.
EJBs are a way for complicated sites to design the back end that will
be used by servlets/JSPs to handle the front end.
