Um, here I have to apologize for BEA's product naming, in which the name
is slapped on everything. I was specifically talking about "Weblogic

from Adam Bosworth's
Crossgain startup when it was acquired by BEA. Adam Bosworth is the
person I have
been referring to as "my boss" in previous email; his title (get this)
is now "Chief Architect
and Senior Vice President for Advanced Development". I'm in the little

But with WLW you can do quite a lot without having to understand much
about these things.
You don't need to know anything about EJB to speak of. You have to know
about configuring JMS, but you never use the JMS API directly because
it's all hidden inside
a "control". The JTA stuff is entirely hidden from you.

Yes, that would all be great, and people have been talking about it as
long as I've been
around. There was a group at MIT called the "Automatic Programming"
was well-established when I showed up in 1976 or so. It appears to be
turning out to
be an extremely hard problem to make such a system that is ready for

That sure would be great. If you had it you could probably make real
money selling it.
Well, if you wanted to make your own thing that does what SAP does,
be a fairly large undertaking.

What, the argument that the principles you are talking about might,
someday, lead to such
a wonderful product? Or the argument that you actually have such a
product that Merrill
Lynch can buy tomorrow? The stuff you're talking about sounds like an
direction, for sure. But I'm just pointing out that (a) it has been an
exciting research direction
for around thirty years already, and (b) it is still not something that
one can go out and buy.
That said, sure, it sounds great.

Absolutely. When I first looked at Eclipse last summer I was susprised
that there was no
Gnu Emacs plugin. Is there STILL no Gnu Emacs plugin? That's so weird
that it makes
me wonder whether there isn't some deeper reason, e.g. maybe the Eclipse
isn't quite as rosy as they'd have you believe? But I don't really know
anything much about it...

Of course you have to remember that back when Symbolics was started,
there was really
no such thing as cross-vendor code. No code that ran on a Data General
machine also ran
on a Digital machine, and the same for Interdata and Wang and Prime.
Nothing. I know that's
hard to believe these days, but that's how it was. The whole concept of
"the Unix code base,
which runs on all the Unix machines from many different vendors" didn't
really start happening
for real until about 1985, at which time Symbolics, as a corporate
entity, failed to grasp its significance

Hey, as soon as my team completed Statice, I told Symbolics management
in no uncertain
terms that what had to be done was to make it portable. They were not
and I quit to co-found Object Design.
CLIM really did run on Common Lisp, hence the name, no?

In retrospect, of course, yes, that's how it should have been done.
Symbolics and Lucid,
for example, really should have merged. But it all looked so different
back then, inside
our little reality-distortion-field.
