Re: Ada and Java (kudos included)

Take this a step further.  Currently, a drawback to Java is in the
actual runtime performance.  Now the current "hot topic" in Java is the
"Just in Time" compiler, which takes jcode to native code. It will be
interesting to see if performance concerns go away then.

I remeber seeing Tucker's work back at Tri-Ada, and was impressed then.
While I don't personally think Java will rule the (language) world, I
think Intermetrics has both  anticipated the direction most commercial
concerns are heading, and further demonstrated that Ada has a role in
that future.

Good work, folks.... now we just need hype the heck out of it

(BTW, at the netscape developer conference, it was asked how many people
used Ada95, before the speaker pointed out that the first solid jcode
system was based on an Ada95 product.  Not sure who did that talk, but
apparently it made someone notice, as several attendees mentioned it to
me at our exhibit)

As this technology becomes available it will in some cases be built
into Net browsers.  When you download an applet and execute it it will
be just-in-time-compiled by your browser.

If so Ada will be able to piggy-back on this new technology too.
Applets will be written in Java or Ada 95 or maybe even some other
language, compiled to bytecodes by their developers, put on the net,
and then the browser will do the native code generation.  Ada 
should fit in perfectly.
